7x14 On The Grow Microgreen Tray Kit

⚠️ PRODUCT UPDATE (2/9/26): We are expecting to have this product back in stock in roughly 2 weeks

Compact • Reusable • Designed for Home Growing

Our most popular microgreen tray kit. The 7x14 On The Grow Microgreen Tray Kit makes growing microgreens at home simple and reliable—whether you're brand new or already growing regularly. With a compact footprint perfect for countertops, shelves, or windowsills, this all-in-one system provides everything except seeds, letting you choose exactly what varieties you want to grow.

Why This Kit Works

Beginner-Friendly Design: No guesswork required. Grow soil-free using the included reusable silicone grow medium, or use soil/coco coir if you prefer. Step-by-step YouTube tutorials and our comprehensive blog guide show exactly how to use this kit from seed to harvest.

Right-Sized for Home Growing: Produces enough microgreens to last a small family a few days per tray. Rotate multiple trays for a steady supply without overwhelming your kitchen. The smaller footprint fits where larger 10x20 trays won't.

Thoughtful Features:

  • Mesh tray nests securely in reservoir for easy watering
  • Humidity dome flips to serve as temporary tray rest during maintenance
  • Tray handles double as support points for mesh tray
  • Water levels visible at a glance—check every few days instead of daily

Built to Last: Food-safe PP (Polypropylene) plastic construction. Thick, sturdy trays that hold up to regular washing and repeated use. Customers consistently mention how solid these feel compared to cheaper options.
