The 7x14 On The Grow Microgreen Tray Kit is a complete home growing system with everything you need except seeds — a mesh tray, water reservoir, humidity dome, two reusable silicone grow mediums, and a scraper tool. Compact enough for a countertop, the mesh tray sits above the reservoir for simple passive bottom-watering. Grow soil-free with the included 1.2mm silicone medium, or use soil or coco coir instead.
Why this kit works
Beginner-friendly: No guesswork. Grow soil-free with the included reusable silicone medium, or switch to soil/coco coir if you prefer. Step-by-step YouTube tutorials and our complete blog guide walk you through seed to harvest.
Right-sized for home growing: Each tray produces enough microgreens to last a small family a few days. Rotate multiple trays for a steady supply. The 14.4" x 7.25" footprint fits windowsills and shelves where a 10x20 tray won't.
Thoughtful design: The mesh tray nests securely in the reservoir for easy watering, the humidity dome flips over to serve as a temporary tray rest during maintenance, and water levels are visible at a glance — check every few days instead of daily.
Built to last: Food-safe PP (polypropylene) trays are thick and sturdy, holding up to regular washing and repeated use.

Care & maintenance
Trays: hand-wash or dishwasher safe (top rack, no heat). Store out of direct sunlight.
Silicone grow medium: remove roots with the included scraper, wash with warm water and a free-and-clear (silicone-safe, food-safe) soap, sanitize with boiling water for 1–2 minutes, then air dry fully before storage.
FAQ
What comes in the kit? A mesh tray, a reservoir base tray, a clear humidity dome, two 7" x 14" reusable silicone grow mediums (1.2mm holes), and a scraper/cleaning tool.
What do I still need to buy? Seeds, and optionally grow lights and liquid fertilizer. Soil or coco coir only if you choose not to use the included silicone medium.
How much does one tray yield? Enough microgreens to last a small family a few days. Rotate multiple trays for a steady supply.
Can I use soil instead of the silicone medium? Yes. The kit works soil-free with the silicone medium, or with soil or coco coir if you prefer.
How does watering work? The mesh tray nests in the reservoir for passive bottom-watering. Water levels are visible at a glance, so you check every few days instead of daily.
Do I need fertilizer? The silicone medium is inert and adds no nutrients, so feed with a liquid fertilizer the same way you would on coco coir.
How many times can I reuse the silicone sheets? 20 to 30+ grow cycles per sheet with proper cleaning and flat storage.
Are the trays dishwasher safe? Yes — top rack, no heat. They're also fine to hand-wash.
Will it fit my windowsill? The external size with the dome on is 14.4" L x 7.25" W x 4.2" H — small enough for most windowsills and shelves where a 10x20 tray won't fit.
Is the silicone food-safe? Yes — it's food-grade, platinum-cured silicone, 3rd-party tested for FDA compliance and LFGB compliant.
Is there a warranty? The silicone reusable grow mediums carry a 1-year warranty.
Do you ship internationally? We currently ship within the U.S. and Canada only. Free U.S. shipping over $65.
