10x20 Heavy Duty Microgreen Trays - Shallow - Bootstrap Farmer

Looking for trays that can handle years of serious growing? Bootstrap Farmer's 10x20 Heavy Duty Shallow Trays are made for growers who need professional-grade equipment that won't crack, warp, or fail after a few uses. Made in the USA from extra-thick, food-safe plastic, these trays are designed for microgreens, sprouting, seed starting, and fodder systems.

Why These Trays Stand Out

Extra-thick construction: At 1.8-2.0mm thick, these aren't your typical flimsy trays. The bottom is 2mm thick with 1.8mm sidewalls—thick enough to support up to 50 pounds without bending or warping. We've grown countless microgreen varieties on these trays both indoors under grow lights and outdoors with excellent results season after season.

Shallow profile, big benefits: The 1¼" shallow depth is made for microgreen production. This allows you to cut your microgreens as low as possible to maximize harvest weight while minimizing the amount of growing medium and water needed. Less waste, more efficiency.

Smart drainage design: Each  mesh tray features strategically placed drainage holes—small enough to hold growing media in place, but large enough to drain excess water efficiently. This design helps prevent mold issues before they start while enabling effective bottom-watering when nested inside a solid tray.

Made to last: Food-safe #5 PP (Polypropylene) plastic that's BPA-free, dishwasher-safe (top rack), and built from recycled post-consumer plastic. With proper care and storage out of direct sunlight, these trays will serve you for years. Backed by Bootstrap Farmer's 2-year warranty against cracks and degradation (you will need to reach out to them directly)

Compatible Growing System

These trays work perfectly with our 10x20 Silicone Reusable Grow Medium for a complete soil-free setup. The inner dimensions are designed to fit our 19.65" x 9.5" grow mediums precisely.

Modular tray configurations: Need more flexibility? Two of our Bootstrap Farmer 10x10 Trays fit side-by-side perfectly inside a 10x20 tray, letting you grow different varieties in the same footprint. For testing small batches or variety trials, eight of our Bootstrap Farmer 5x5 Trays fit inside a single 10x20, giving you ultimate flexibility.

Easy labeling and separation: Our Microgreen Tray Clip Labelers are specifically designed to clip over the finger slots on these Bootstrap Farmer trays. They make labeling varieties and harvest dates effortless while also simplifying tray separation during watering and crop inspection.

Bottom-watering setup: Nest a tray with drainage holes inside a solid tray (no holes) for efficient bottom-watering. The side cutouts make lifting the top tray easy for checking water levels.

Care & Longevity

Cleaning: Dishwasher-safe (top rack recommended - no heat). Can also be hand-washed with warm, soapy water.

Storage: Keep trays out of direct sunlight when not in use. UV exposure will degrade any plastic over time, but proper storage ensures these trays last for years.

Durability: The extra-thick construction resists cracking, warping, and wear from repeated use. These trays won't buckle when you're moving full trays of microgreens.
