Speedlings are our best selling transplant containers. Reusable polystyrene tray with individualized pyramid shaped cells which virtually eliminate transplant shock. Advantages: undamaged roots (plants and all the soil pop out cleanly); no tearing or entangled roots, no spreading of root pests or diseases; a better root system (when the bottom of the tray is exposed to air, the taproot is air pruned promoting the growth of feeder roots that are directed downward instead of spiraling around the cell, enabling the plant to begin growing immediately after transplanting); reduced damping off (due to excellent drainage). In addition, 95% (minimum) of Speedling transplants survive in the field. Trays are reusable for many years. For more about growing with Speedlings, see the Product Use Information, below. Note: all trays are 26-5-8 x 13-5-8 overall with slight variance on the height. This tray has 72 cells which are 2 square x 3 deep.
10+ years and going strong. Going on over 10 years, I use the 72-cell version every spring either under florescent lights or in the greenhouse. So easy to pop them out and plant them up, or put them straight into the ground.Review by springtime (on 5/6/14)
I have had a 72 cell tray for about 20 years - just ordered 3 more in smaller sizes. I use a good commercial seed starting mix; sometimes the root ball sticks to the Styrofoam but I slide a thin paring knife along one edge and pop it up.Review by Carol in the garden (on 4/11/14)
