The Bootstrap Farmer 10x10 Heavy Duty Microgreen Trays are extra-thick, USA-made shallow trays in a versatile half-size format — the same professional-grade build as the 10x20 trays, sized so two fit side-by-side inside a standard 10x20. At 1.8–2.0mm thick, they resist cracking and warping crop after crop. Made for microgreens, sprouting, seed starting, wheatgrass, and fodder.
Why these trays stand out
Extra-thick construction: A heavy-duty 1.8–2.0mm build that supports substantial loads without bending or warping — they hold their shape through countless growing cycles where thin trays buckle.
Shallow profile, real benefit: The 1¼" depth lets you cut microgreens as low as possible to maximize harvest weight while using less growing medium and water. Less waste, more yield per tray.
Smart drainage design: The slotted tray's drainage holes are small enough to hold growing media in place but large enough to drain excess water, which helps prevent mold before it starts and enables efficient bottom-watering when nested inside a solid tray.
Modular growing advantage: Two 10x10 trays fit perfectly side-by-side inside a standard 10x20 tray, so you can grow different varieties in the same footprint, test new crops, or stagger harvests using the same infrastructure.
Made to last: Food-safe #5 PP (polypropylene), BPA-free, dishwasher-safe (top rack), and made from recycled post-consumer plastic. Stored out of direct sunlight, they last for years. Backed by Bootstrap Farmer's 2-year warranty against cracks and degradation (warranty claims go directly through Bootstrap Farmer).

Best for
- Microgreens (all varieties)
- Sprouting seeds and wheatgrass
- Seed starting for transplants
- Fodder systems
- Both hydroponic and soil-based growing
- Growing multiple varieties in one 10x20 footprint
- Testing new crops or smaller production batches
- Home growers with limited space
The shallow depth plus proper drainage makes these ideal for dense seeding and quick-turn crops like microgreens, where maximum airflow helps manage humidity and prevent mold.
Holes vs. solid: which do you need?
This is the slotted tray, with drainage holes. For bottom-watering, nest this holed tray inside a solid 10x10 tray with no holes — the holed tray holds your crop and media, the solid tray holds the water. Most growers need both: one holed and one solid per growing slot.
Build a complete setup
Pair with a reusable medium: These trays work with our 10x10 Reusable Grow Mediums (silicone and stainless steel) for a clean, soil-free setup.
Modular flexibility: Two 10x10 trays fit side-by-side inside a 10x20 tray, so you can grow different varieties in one footprint, or use one tray for watering while growing in the other.
Important sizing note: Because Bootstrap Farmer trays are extra-thick, four 5x5 trays will not fit properly inside a single 10x10. For small-batch testing with 5x5 trays, run them in a 10x20 instead — eight 5x5s fit in one 10x20.
Label and separate: Our Microgreen Tray Clip Labelers are designed for Bootstrap Farmer trays — they make labeling varieties and harvest dates effortless and simplify separating trays during watering and inspection.
Care & longevity
Cleaning: dishwasher-safe (top rack, no heat) or hand-wash with warm, soapy water.
Storage: keep trays out of direct sunlight when not in use — UV exposure degrades any plastic over time, and proper storage keeps these lasting for years.
Durability: the extra-thick construction resists cracking, warping, and wear, holding its shape and strength through countless growing cycles.
