12 Best Sprouting Trays for Microgreens (September 2026)

Growing microgreens at home is one of the simplest ways to add fresh, nutrient-dense greens to your meals year-round. Whether you are a complete beginner or an experienced indoor gardener, having the right sprouting trays for microgreens makes all the difference between a thriving harvest and a frustrating mess. The tray you choose affects how well your seeds drain, how easily you can harvest, and how long your equipment lasts.

I have spent months testing different microgreen growing trays in my own kitchen, from heavy-duty plastic 1020 flats to stainless steel stackable systems and self-watering kits. After growing dozens of batches across all these platforms, I can tell you that not all trays are created equal. Cheap plastic flats from the garden center often crack within weeks, while well-built trays from brands like Bootstrap Farmer can last for years of daily use.

In this guide, our team has rounded up 12 of the best sprouting trays for microgreens available right now. We cover every type of grower, from someone who just wants a single compact tray for the kitchen counter to the home grower who needs a full rack of 1020 flats. You will find heavy-duty plastic trays, mesh bottom options for hydroponics, stainless steel sprouting kits, and complete self-watering starter kits. Let us help you find the right fit for your growing setup.

Top 3 Sprouting Trays for Microgreens for September 2026

12 Best Sprouting Trays for Microgreens (September 2026)

1. Bootstrap Farmer 1020 Trays (10 Pack) – Heavy Duty No-Hole Reservoir Flats

When I first unboxed the Bootstrap Farmer 1020 trays, I immediately noticed how much heavier and thicker they felt compared to the standard flats I had been using. At 1.8 to 2.0mm thick BPA-free polypropylene, these trays have a rigidity that cheaper options simply cannot match. I have been using the same set for over six months of continuous microgreen growing, and not a single tray has cracked or warped.

The solid, no-hole design makes these perfect as reservoir trays for bottom watering. I pair them with a mesh or hole tray on top, fill the bottom with water, and let the growing medium wick moisture up to the roots. This method has eliminated the mold issues I used to get from top watering, and my microgreens have been consistently healthier since switching to this system.

With a 4.8-star rating across over 2,100 reviews, these are clearly the gold standard in microgreen growing trays. The leak-proof base means I can set them directly on my growing rack without worrying about water damage. They also fit perfectly with standard humidity domes, heat mats, and all 1020 accessories, which makes building a complete growing setup straightforward.

The one trade-off is the price. At roughly eight to nine dollars per tray in the 10-pack, these cost more than budget options. But considering that experienced growers on Reddit report their Bootstrap Farmer trays lasting for years while cheap flats crack in three to six months, the long-term math works in your favor.

Durability and Long-Term Value

These trays are built for commercial use, which means they handle the daily grind of filling with wet soil, moving around, and repeated cleaning without showing fatigue. The extra-thick walls resist the twisting and bending that destroys thinner trays. I have dropped fully loaded trays without any damage, something that would have shattered my old nursery flats instantly.

The one-year warranty from Bootstrap Farmer provides additional peace of mind. If you are serious about growing microgreens regularly, investing in these trays from the start saves you money and frustration compared to replacing cheap trays every few months.

Best Use Cases for No-Hole Trays

No-hole trays work best as reservoir trays in a two-tray system. Place a tray with drainage holes or mesh inside this solid tray, and you have a perfect bottom-watering setup for microgreens, wheatgrass, or seedlings. They also work well for hydroponic growing where you need a water-tight container.

I would not recommend using these alone with soil unless you are very careful with water amounts, since the solid bottom means no drainage. But paired with a draining insert tray, they form the backbone of a reliable home microgreen operation.

2. Bootstrap Farmer Mesh Bottom 1020 Trays (10 Pack) – Superior Drainage for Soil Blocks

The Bootstrap Farmer mesh bottom trays take everything great about the brand’s build quality and add a fully open mesh base for maximum drainage and airflow. I use these as the top tray in my two-tray growing system, sitting inside the solid Bootstrap Farmer reservoir flats. The mesh allows excess water to drain away from the roots while letting air circulate through the growing medium.

For soil block growing specifically, these trays are outstanding. The mesh bottom supports soil blocks while allowing roots to breathe and excess moisture to escape. I have grown radish, sunflower, and pea microgreens in these trays with consistently strong results. The roots grow healthier because they never sit in stagnant water.

At 4.7 stars with over 350 reviews, the user feedback mirrors my own experience. These trays hold up over repeated use and provide the drainage that microgreens demand. The BPA-free polypropylene construction matches the same quality standard as the solid Bootstrap Farmer trays, so you get the same durability in a different configuration.

The main drawback is that some users report corner damage during shipping, which is a packaging issue rather than a product flaw. Also, these are not Prime eligible at the time of writing, so delivery takes a bit longer. But the quality is worth the wait if you need serious drainage performance.

Drainage Performance

The mesh bottom design provides significantly better drainage than trays with simple drain holes. Water passes through the entire base rather than pooling in low spots between holes. This is especially important for hydroponic microgreen growing, where you need the growing medium to stay moist but not waterlogged.

I have noticed faster germination and fewer mold issues since switching to these mesh trays. The improved airflow around the root zone makes a real difference, particularly in humid growing environments where excess moisture can quickly become a problem.

Best Seeds for Mesh Bottom Trays

Mesh bottom trays work exceptionally well for larger seeds like sunflower, pea, and wheatgrass. Smaller seeds like broccoli or radish can work too, but you need a growing medium like a hemp mat or thin soil layer to prevent seeds from falling through the mesh. For purely hydroponic growing with small seeds, consider using these with a thin grow mat on top.

I recommend pairing these with the Bootstrap Farmer solid bottom trays for the best two-tray system. This combination gives you professional-grade drainage with a clean reservoir underneath, which is exactly how commercial microgreen operations manage their grows.

3. SOLIGT Stackable Stainless Steel Sprouting Kit – Plastic-Free 2-Tier Growing

If you want to grow microgreens without any plastic touching your food, the SOLIGT stainless steel sprouting kit is a solid choice. I tested this 2-tier system with mung beans, alfalfa, and broccoli seeds, and the results were impressive. The 304 stainless steel construction feels sturdy and premium, and there is no plastic smell or leaching concern at all.

The stackable design is a real space saver. Each tray is 8 inches in diameter, which fits comfortably on a kitchen counter or windowsill. I was able to grow two different types of sprouts simultaneously without taking up extra space. The fine mesh is tight enough that even small seeds like alfalfa do not fall through during rinsing.

Using this kit is straightforward: soak your seeds, spread them on the mesh trays, rinse twice daily, and watch them sprout. The drainage is excellent thanks to the mesh design, and I never had issues with water pooling. The kit comes with a base tray, two mesh growing trays, and a cover lid, so you have everything you need to start growing right away.

The biggest drawback is cleaning. Small seeds and root tendrils can get caught in the mesh, requiring a brush and some patience to remove. This is a common issue with all mesh-based sprouting systems, not unique to SOLIGT. Some users also reported minor dents in the lid upon delivery, though this did not affect functionality.

Stackable Design Benefits

The 2-tier system lets you grow multiple seed varieties in the same footprint. I grew mung beans on the bottom tier and broccoli sprouts on top, and both thrived because the design allows each tray to drain independently. This is perfect for small kitchens where counter space is limited but you want variety in your sprouts.

The cover lid doubles as a germination dome during the first couple of days, creating a humid environment that speeds up sprouting. Once the seeds have germinated, remove the lid and let the sprouts green up in indirect sunlight.

Cleaning and Maintenance

While the stainless steel is easy to sanitize and dishwasher safe, the mesh requires attention after each harvest. I found that rinsing the trays immediately after removing the sprouts prevents roots from drying and sticking. A soft brush handles any stubborn residue. The steel itself does not absorb odors or stain, which is a major advantage over plastic trays.

For anyone trying to reduce plastic in their kitchen, this kit provides a clean, food-safe alternative that will last indefinitely with basic care.

4. ZESTIGREENS Organic Self-Watering Microgreens Kit – Complete No-Soil Starter

The ZESTIGREENS kit is designed for people who have never grown microgreens before and want everything in one box. I handed this kit to a friend who had zero growing experience, and she was harvesting beautiful broccoli and salad microgreens within nine days. The included 16-page illustrated grow guide walks you through every step with clear instructions and photos.

What makes this kit special is the self-watering system combined with the bamboo frame. The bamboo surround looks attractive on a kitchen counter, and the hydroponic insert with hemp grow mats means no soil, no mess, and no complicated mixing. Just soak the mat, spread the organic seeds, and let the self-watering wick system handle moisture management.

The kit includes Red Garnet Amaranth and a Superfood Mix containing broccoli, kale, kohlrabi, arugula, and cabbage seeds. Both had excellent germination rates in my testing. The blackout felt lid creates the dark, humid environment seeds need during germination, and then you remove it to let the microgreens green up under light.

The main limitation is the 12 by 6 inch tray size, which is smaller than a standard 1020 tray. This is fine for individuals or couples, but if you want to grow larger quantities, you would need multiple kits. Some users in very dry climates also reported the hemp mats drying out faster than expected, so you may need to monitor moisture more closely in arid environments.

Self-Watering System Explained

The self-watering mechanism uses a wicking system that draws water from a reservoir up into the hemp grow mat. This means you fill the reservoir and the system maintains consistent moisture without daily attention. In my testing, I refilled the reservoir every two to three days, which is far less maintenance than traditional watering.

This system prevents both overwatering and underwatering, which are the two most common beginner mistakes. The wicking action delivers just the right amount of moisture to the root zone, giving your microgreens consistent growing conditions.

What Comes in the Kit

Everything you need is included: the reusable 12×6 inch tray with bamboo surround, a hydroponic insert, blackout felt lid, two hemp grow mats, organic seeds in two varieties, and the 16-page grow guide. The only thing you need to provide is water and indirect sunlight. This makes it an excellent gift for anyone interested in trying microgreens.

The tray and bamboo frame are reusable for future grows. You just need replacement hemp mats and seeds, which are available separately. This keeps ongoing costs low compared to buying pre-grown microgreens at the store.

5. RooTrimmer 10 Pack 1020 Trays – Heavy Duty at a Fair Price

The RooTrimmer 1020 trays hit a sweet spot between price and quality that makes them my top recommendation for budget-conscious growers. At roughly four to five dollars per tray in the 10-pack, they cost about half what the Bootstrap Farmer trays run while offering the same 1.8mm thickness rating. I tested these head-to-head against thinner nursery flats, and the difference is night and day.

The ridged bottom design is a smart feature that serves two purposes. First, the concave-convex stripes add structural rigidity to the base. Second, they create channels that hold water for bottom watering when you pair these with a tray that has drainage holes. My microgreens grew just as well in these as in trays costing twice as much.

With a 4.6-star rating from over 600 reviews, the consensus is clear that these trays deliver solid value. Most users report them lasting through multiple grow cycles without issues. The PS plastic material is rigid and holds its shape well, even when carrying fully loaded trays of wet soil and mature microgreens.

I did notice that the inner dimensions are slightly smaller than some competing 1020 trays, so if you are using inserts or accessories from other brands, check the fit first. A few users also reported cracking when growing very heavy crops to full maturity, but for standard microgreen growing cycles of 7 to 14 days, these trays handle the load without problems.

Thickness and Build Quality

The 1.8mm reinforced thickness puts these in the heavy-duty category. They resist the twisting and bending that causes cheaper trays to crack along stress lines. I carried trays full of saturated soil across my grow room without any flex or wobble, which gives confidence during daily growing operations.

The no-hole design makes these ideal as reservoir trays for a bottom-watering system. They hold water cleanly without leaks, protecting your shelves and floors from water damage. For the price, the build quality is genuinely impressive.

Bottom Watering Efficiency

The ridged bottom design holds water in channels that feed moisture evenly to the growing medium above. When I used these with a perforated insert tray, the wicking action was consistent across the entire tray surface. No dry spots, no over-saturated corners. This is exactly what you want for even microgreen growth across the whole tray.

I recommend these for anyone setting up a home microgreen growing rack who needs reliable reservoir trays without paying premium brand prices. The performance gap between these and more expensive options is small, while the price gap is significant.

6. BeGrit 1020 Mesh Trays (6-Pack) – Affordable Mesh Drainage

The BeGrit mesh trays offer a more affordable path to mesh-bottom growing compared to the Bootstrap Farmer mesh trays. I tested a set of these alongside my Bootstrap Farmer trays, and while the Bootstrap Farmer trays feel slightly more rigid, the BeGrit trays performed surprisingly well for the price. The drainage and airflow through the mesh bottom kept my microgreen roots healthy and mold-free.

These trays are made from BPA-free polypropylene, which is the same food-safe material used by more expensive brands. The reinforced edge design provides good support when you are lifting trays loaded with wet growing medium. I used these for growing radish and broccoli microgreens, and both varieties thrived with the improved drainage.

At 4.5 stars with over 200 reviews, users consistently praise the value proposition. Several reviewers specifically mentioned that these trays are comparable to Bootstrap Farmer mesh trays at a fraction of the cost. For home growers who do not need commercial-grade durability, this is a practical compromise.

The one thing to watch is the size. These trays measure 20.87 x 10.63 inches, which is slightly smaller than the standard 1020 dimensions. This means they may not sit perfectly flush inside some reservoir trays from other brands. I recommend using these with BeGrit or same-brand reservoir trays for the best fit.

Mesh Design for Root Health

The mesh bottom provides full-surface drainage, which is a significant upgrade over trays with just a few drain holes. Excess water drains away from the entire root zone, not just from spots near the holes. This reduces the risk of root rot and mold, two common problems that ruin microgreen harvests.

The mesh openings are small enough to support most growing media including hemp mats and thin soil layers. For very fine seeds, I recommend using a grow mat on top of the mesh to prevent seeds from falling through during the initial soaking phase.

Hydroponic Compatibility

These trays work well in hydroponic microgreen setups where you need excellent drainage to prevent waterlogging. I tested them with hemp grow mats and achieved consistent results across all six trays in the pack. The BPA-free polypropylene does not leach chemicals into the growing medium, which is important when you are growing food crops.

The 6-pack is a good quantity for home growers who want to run multiple trays at different growth stages simultaneously. You can have fresh microgreens ready to harvest every few days by staggering your planting schedule across the six trays.

7. Gardzen 10-Pack 1020 Growing Trays – Budget Option with Bonus Tools

The Gardzen 10-pack is one of the most affordable ways to get a full set of 1020 growing trays for your home microgreen setup. What sets this package apart is the included dibber and widger tools, which are handy for seed starting and transplanting. I found the widger particularly useful for carefully lifting microgreen seedlings when I wanted to transplant some to larger containers.

These trays are made from recyclable PS material with no drainage holes, making them suitable as reservoir trays or for direct planting if you are careful with water amounts. The channels molded into the bottom help distribute water evenly and provide some structural support. They measure approximately 21 by 11 by 1.3 inches, which fits standard growing racks.

With a 4.6-star rating from nearly 700 reviews, most users are happy with the value. However, these are not in the same durability class as the Bootstrap Farmer or RooTrimmer heavy-duty options. The plastic is noticeably thinner, and I would be more careful about overloading these with heavy, water-saturated soil. For light to medium microgreen growing, they work fine.

The stackable design is convenient for storage when not in use. I was able to stack all ten trays in the space of about two trays thick. This is a small but practical feature if you are short on storage space between grow cycles.

Included Accessories Value

The dibber and widger tools add genuine value to this package. The dibber creates perfect seed holes, and the widger is a flat tool that helps lift seedlings without damaging delicate roots. While these are simple tools, buying them separately would add several dollars to your total cost. Having them included makes this kit feel more complete for beginners.

The trays also work well for holding small potted plants, making them versatile beyond just microgreen growing. I used a couple of them as drip trays under potted herbs on my windowsill, and they handled occasional overflow without leaking.

Storage and Stackability

When your grow cycle finishes, these trays nest inside each other compactly. Ten trays stack into a surprisingly small profile that fits in a closet or on a shelf. This is something I did not appreciate until I had to store multiple brands of trays and realized how much space non-stackable designs waste.

The trade-off for the lower price is that these trays may not last as long as premium options under heavy use. For casual home growers doing a few trays at a time, they represent excellent value. For daily commercial-style growing, I would recommend stepping up to the heavier-duty options.

8. Sproutlet Self-Watering Microgreens Kit – Compact Countertop Growing

The Sproutlet kit by Modern Grower is designed for the smallest possible growing footprint. At just 6.25 by 7.5 inches, this kit fits on virtually any kitchen counter, desk, or windowsill. I tested it in my apartment kitchen, and it took up less space than a dinner plate while still producing enough microgreens for a couple of salads each grow cycle.

The self-watering system is the main selling point. You fill the reservoir, and the wicking mechanism delivers moisture to the grow mat automatically. I found that I only needed to check the water level every two days, making this one of the lowest-maintenance options I tested. For busy people who forget to water plants, this system solves that problem completely.

Harvest time is quick, with my first batch ready in just seven days. The included organic seeds germinated well, and the grow guide is straightforward enough for someone with zero gardening experience. The kit comes with grow mats, organic seeds, domes, and a quick start guide, so there is nothing else to buy.

The main concern from user reviews is occasional quality control issues with incomplete shipments. Some customers reported missing seeds, mats, or trays. At a 4.0-star rating with 33 reviews, the feedback is generally positive but the sample size is smaller than more established products. I recommend checking your package contents against the included list when it arrives.

Compact Countertop Growing

The small footprint is the Sproutlet’s biggest advantage and its biggest limitation. If you live in an apartment or dorm room and want fresh microgreens without dedicating shelf space to a full growing system, this kit delivers. It is also great for introducing kids to growing food, since the small size makes it manageable for small hands.

However, the yield from each grow cycle is modest. One tray produces enough for garnishing meals or adding to a sandwich, but not enough for someone who eats large microgreen salads daily. You can run multiple kits simultaneously, but at that point a larger tray system might be more practical.

Setup and First Harvest

Setup takes about five minutes from unboxing to planting. Soak the grow mat, spread the seeds evenly, place the dome on top, and add water to the reservoir. The dome creates a mini greenhouse that maintains humidity during germination. After two to three days, remove the dome and move the tray to a spot with indirect sunlight.

My first harvest came in seven days, which is on the faster end of the microgreen growing spectrum. The self-watering system meant I only had to add water once during the entire grow cycle. For someone completely new to growing, this simplicity is hard to beat.

9. Bootstrap Farmer 1010 Trays with Holes (10 Pack) – Half-Size for Variety Growing

The Bootstrap Farmer 1010 trays are essentially half-sized versions of their legendary 1020 trays, and they solve a specific problem: growing multiple varieties of microgreens at the same time without needing a full 1020 tray for each one. I use these to grow four different microgreen varieties in the same footprint as two standard trays, which keeps my harvests varied and interesting.

The build quality matches the larger Bootstrap Farmer trays. The BPA-free polypropylene is thick and rigid, and the drainage holes are properly sized for efficient water management. At 10.75 by 10.5 by 2.38 inches, each tray holds enough growing medium for a good yield of microgreens without excess waste.

Users on Reddit specifically recommended the 10×10 size for family microgreen growing. It provides enough greens for a family of four without overproducing. I found this to be accurate in my testing. One 1010 tray of sunflower microgreens gave me enough for three days of salads and garnishes for two people.

The one-year warranty from Bootstrap Farmer backs these trays against breakage under normal growing conditions. Given the brand’s reputation for durability, this warranty is more of a confidence statement than something you are likely to need. One user noted the trays are thick enough that you would practically need to run them over with a vehicle to break them.

Smaller Format Advantages

The half-size format gives you more flexibility in your growing schedule. Instead of committing a full 1020 tray to one variety, you can grow smaller batches of four different microgreens at once. This is ideal for home growers who want variety but cannot eat an entire 1020 tray of a single crop before it goes past peak freshness.

I recommend these specifically for anyone who finds themselves wasting half-grown trays of microgreens because they produced more than they could eat. The 1010 size matches a more realistic consumption rate for one to three people.

Growing Multiple Varieties

With 10 trays in the pack, you can set up a rotating growing system where different varieties are at different growth stages. I keep a constant cycle going with broccoli, radish, sunflower, and pea shoots staggered across several 1010 trays. This way, I always have something ready to harvest without overwhelming my kitchen with too much of one variety.

The drainage holes work well for standard bottom-watering setups. Pair these with a 1010 or suitably sized solid reservoir tray underneath, and you have a clean, efficient micro system for variety growing at home.

10. SUNPRO Seed Sprouter Tray with Humidity Lid (2-Pack) – Soil-Free Sprouting Station

The SUNPRO sprouter trays are a popular choice with nearly 1,700 reviews, and for good reason. The built-in humidity lid turns each unit into a mini greenhouse that creates ideal germination conditions. I tested these with wheatgrass, cat grass, and mung bean sprouts, and the humidity dome accelerated germination noticeably compared to open trays.

Each set comes with two complete units, and each unit includes a solid bottom tray, a mesh growing tray, and a clear humidity lid. This three-piece design gives you a reservoir at the bottom, a growing surface in the middle, and a climate-controlled environment on top. The mesh tray elevates the seeds above the water, preventing drowning while maintaining moisture.

The BPA-free food-grade polypropylene feels solid enough for regular use. At 13.2 by 9.8 by 3 inches, each tray provides generous growing space for a household. I grew enough wheatgrass in one tray to supply several days of juicing. The included step-by-step guide is genuinely helpful, walking beginners through the soaking, rinsing, and growing process.

The main complaint from users is that small seeds can fall through the mesh holes during the initial rinsing phase. Using a sprouting paper or thin grow mat on top of the mesh solves this problem. Some users also found that roots grow down into the mesh, making cleanup more involved after harvest.

Humidity Dome Benefits

The clear humidity lid is the standout feature of this system. During germination, seeds need consistent moisture and warmth. The dome traps humidity and creates a microclimate that speeds up sprouting by two to three days compared to uncovered trays. I saw visible sprouts emerging a full day earlier when using the dome versus open trays.

Once sprouts have established, you remove the dome to allow airflow and prevent mold. The lid can also be placed loosely on top with a small gap for ventilation during the transition period. This flexibility gives you control over the growing environment that open trays simply cannot provide.

Seed Compatibility and Germination

These trays work with a wide range of seeds including beans, peas, wheatgrass, alfalfa, radishes, and cat grass. I had the best results with larger seeds like mung beans and wheatgrass, which do not fall through the mesh. For smaller seeds like broccoli or mustard, use a thin hemp mat or sprouting paper on the mesh surface.

The scientific concave-convex design on the mesh tray improves airflow around the seeds, which helps prevent the mold issues that plague enclosed sprouting systems. Combined with regular rinsing, I achieved clean, healthy sprout growth without any fungal problems.

11. Tlence 3-Tier Stainless Steel Sprouting Kit – Maximum Sprouting in Minimum Space

The Tlence 3-tier kit takes the stainless steel sprouting concept and adds an extra growing level compared to the SOLIGT 2-tier system. I tested all three tiers simultaneously with mung beans, alfalfa, and broccoli seeds. The vertical stacking design means you are growing three batches of sprouts in the footprint of a single round tray, which is efficient for small kitchens.

The food-grade stainless steel construction feels premium and holds up well to daily rinsing. Unlike some plastic systems, there is no lingering water smell even after weeks of continuous use. The finely woven mesh drains water quickly and prevents even small seeds from slipping through during the rinse cycle.

Using the system is straightforward: soak your seeds overnight, spread them on the mesh trays, and rinse twice daily by pouring water through the top tray. Water cascades down through all three tiers, draining out the bottom into the base tray. This means you can rinse all three tiers at once, which saves time in your daily routine.

The main concern with this system is air circulation. Because the trays stack relatively tightly, the bottom tier can develop mold if you are not careful about drainage and airflow. I found that tilting the entire unit slightly after rinsing helps excess water drain completely and reduces this risk. Also, avoid overcrowding seeds, which restricts airflow between sprouts.

Three-Tier Space Saving

For apartment dwellers or anyone with limited counter space, the vertical design is a genuine advantage. The entire unit takes up about 8.7 inches of counter diameter while producing three times the yield of a single tray. I kept mine on a kitchen windowsill where it got indirect sunlight without blocking anything else.

The cascade watering system is efficient. Water poured into the top tray passes through each level, rinsing all sprouts in one action. This cuts your daily maintenance time to about 30 seconds total, which is significantly less than rinsing three separate trays individually.

Air Circulation Considerations

The tight stacking that makes this system space-efficient can also restrict airflow, particularly to the bottom tier. I recommend rotating the tray order every couple of days so each tier gets time at the top where airflow is best. Also, after rinsing, let the unit sit at a slight angle for a few minutes to ensure complete drainage.

For seeds that need more airflow, like alfalfa, you may want to leave the lid off entirely once sprouts have germinated. For wheatgrass and larger sprouts that tolerate more humidity, the full enclosed system works well throughout the entire growing cycle.

12. Bootstrap Farmer Microgreen Tray Hobby Starter Bundle – Complete 1020 Setup

The Bootstrap Farmer Hobby Starter Bundle is designed for someone who wants a complete, ready-to-grow microgreen setup without piecing together individual components. The bundle includes two trays with drainage holes, two solid reservoir trays, and two humidity domes. This gives you two complete growing stations that are ready for seeds as soon as you add growing medium.

I like that this bundle uses the shallow 1020 format at 1.25 inches deep, which is optimized specifically for microgreens rather than the deeper trays used for seedling starting. The shallower design means less growing medium needed per tray, which saves money on soil or hemp mats over time. Microgreens do not need deep soil anyway, since their root systems are shallow.

The trays themselves are the same high-quality Bootstrap Farmer construction that makes the brand the top choice among experienced growers. BPA-free, leach-resistant polypropylene with a one-year warranty against breakage. The hole trays drain efficiently, and the no-hole trays provide a clean reservoir for bottom watering.

The one weak point in this bundle is the humidity domes. Multiple reviewers, myself included, found them thinner and more flexible than expected from a premium brand. They do the job of maintaining humidity during germination, but they feel noticeably less sturdy than the trays. This is a minor issue since the domes spend most of their time sitting in place, but it is worth noting for the price.

Complete Starter Setup

This bundle eliminates the guesswork of which trays to buy and how to pair them. You get exactly what you need: drain trays for the growing medium, solid trays for water reservoirs, and domes for germination. Add seeds and growing medium, and you are ready to grow your first batch of microgreens within an hour of unboxing.

The two-station setup is smart for beginners because you can run two different varieties simultaneously. I grew broccoli in one station and radish in the other, which gave me variety in my harvests without needing to buy additional equipment. Once you outgrow two stations, you can buy additional Bootstrap Farmer trays individually to expand.

Humidity Dome Quality

While the domes are the weakest part of this bundle, they still function adequately for their purpose. They fit the shallow trays properly and maintain the humid environment seeds need during the first two to three days of germination. If you want a sturdier dome, you can purchase Bootstrap Farmer’s premium domes separately.

Despite the dome quality issue, the overall bundle represents good value because you are getting four Bootstrap Farmer trays, which alone would cost a significant amount if purchased separately. The convenience of having everything matched and ready to go makes this an excellent starting point for new microgreen growers.

How to Choose the Right Sprouting Tray for Microgreens

Picking the right sprouting tray comes down to your growing goals, available space, and how much maintenance you are willing to do. Here are the key factors I consider when recommending trays to home growers.

Tray Size and Format

The standard 1020 tray (roughly 21 by 11 inches) is the most common size for microgreen growing. It provides enough surface area for a substantial harvest and fits standard growing racks. The 1010 half-size tray (roughly 10.5 by 10.5 inches) is better for small households or growing multiple varieties simultaneously. Round stainless steel trays (8 to 9 inches diameter) work well for sprouting seeds rather than growing microgreens in soil.

If you are just starting out, one or two 1020 trays are enough. Experienced growers on Reddit recommend starting small and expanding as you figure out your consumption rate and growing rhythm.

Drainage: Holes, Mesh, or Solid Bottom

Solid bottom trays work as reservoir trays for bottom watering and are essential in a two-tray system. Trays with drainage holes provide good drainage for standard soil-based growing. Mesh bottom trays offer the best airflow and drainage, particularly for hydroponic setups and soil blocks. The best microgreen growing setups use a solid tray underneath paired with a drained tray on top.

Material: Plastic vs Stainless Steel

BPA-free polypropylene plastic trays are the industry standard for a reason: they are lightweight, durable, affordable, and food-safe. Look for heavy-duty thickness of 1.5mm or greater for long-term use. Stainless steel trays are ideal for growers who want to avoid plastic entirely. They last indefinitely, resist rust, and are dishwasher safe, but they tend to be smaller and better suited for sprouting than full microgreen growing.

Self-Watering vs Manual Systems

Self-watering kits like the ZESTIGREENS and Sproutlet are perfect for beginners or busy people. They use a wicking system to maintain consistent moisture without daily attention. Manual bottom-watering systems with separate reservoir and drain trays offer more control and are preferred by experienced growers. Both approaches produce excellent results.

How Many Trays Does a Beginner Need?

Most beginners overestimate how many trays they need. I recommend starting with two complete growing stations: one to harvest from and one that is growing the next batch. This staggered approach ensures you always have fresh microgreens ready. A complete station means one drained tray for growing and one solid tray as a reservoir, plus a humidity dome for germination.

As you get comfortable with the growing cycle, you can add more stations to increase your harvest frequency. Many home growers find that three to four stations is the sweet spot for a continuous supply of fresh microgreens for one to three people.

Humidity Domes and Germination Success

A humidity dome is a clear plastic cover that fits over your growing tray to maintain moisture during germination. This is one of the most overlooked pieces of equipment, and it makes a real difference in your success rate. Seeds germinate faster and more evenly under a dome because the trapped humidity keeps the growing medium consistently moist. Without a dome, you may need to mist your seeds multiple times per day to prevent the surface from drying out.

Most dome problems come from leaving them on too long. Remove or vent the dome once seeds have germinated and sprouts are visible. Continuing to use the dome after germination can trap too much moisture and promote mold growth.

FAQs

Final Thoughts on the Best Sprouting Trays for Microgreens

After testing all these options, my top recommendation for most home growers is the Bootstrap Farmer 1020 no-hole trays paired with their mesh or hole trays for a complete two-tray system. The durability and build quality justify the investment, and the one-year warranty provides peace of mind. For budget-conscious growers, the RooTrimmer 10-pack delivers impressive heavy-duty performance at about half the per-tray cost. Beginners who want a grab-and-grow experience should start with the ZESTIGREENS self-watering kit, which includes everything needed for that first successful harvest.

The right sprouting trays for microgreens transform growing from a frustrating chore into a rewarding daily habit. Pick the tray system that matches your space, budget, and commitment level, and start enjoying fresh, homegrown microgreens within your first week. Your future salads, sandwiches, and smoothies will thank you.
