Our 32 Cell Seed Trays are exclusively designed and sold by Bootstrap Farmer. 

These seedling trays are built to fit 2x2 Rockwool cubes found with many grow tower kits.  These are meant to be reused over and over, season after season. They are perfect for vegetables, herbs, flowers, and germination of seedlings in soil or hydroponics for hobby or commercial growers.

These will fit into any standard 1020 flats, including our super durable propagation trays, sold exclusively by Bootstrap Farmer.  Cells are a bit wider on the top and slightly tapers to the bottom, with drainage holes. The drainage holes allow for roots to continue to grow through the bottom of the cell tray if desired.  They are large enough for roots to find their way, but also small enough to hold moistened vermiculite in place.
