5 x 5 Small Growing Tray Inserts (with Drain Holes)

They are very thin. Did not fit the 10x 20 trays. Had to trim the top edges away to get them to fit the 10 x 20 trays.

easy to use, washable to reuse

Good for a small batch of microgreens.

These work well for small batches of microgreens. I use these for my older seed packs just to try and use them up.
