While Speedling Trays are designed to be used with air circulation space beneath to air prune plant roots, a drain tray is required to capture water when trays are set-up indoors. Youve asked for one for years, and we have finally found one. You can also fill the tray with about 1" of water and float the Speedling Tray on it for continuous watering. Dark green plastic, 31" x 16" x 2" deep.
This came with a giant sticker that suggested it was a boot tray. It was not made for speedling trays and is too large for them. The ridges help drainage, so that's a plus. On the other hand, you can't bottom water. I would not get them again.Review by Picci (on 5/24/13)
