Do RootMaker® Propagation Trays require a special location? In order for complete air flow through all openings, it is recommended to place propagation trays 10”- 12” off the ground if growing outdoors; 16’ – 24” if growing indoors. The amount of air movement at your location is the determining factor. If you see roots extending even just a short distance out of the air-root-pruning openings, then you do not have sufficient air circulation thus you should position the trays higher off the ground.How long should seedlings remain in the propagation cells? The answer is specific to each growing location. As a rule, it is always better to remove seedlings early, even if small amounts of soil mix fall away, versus leaving the plants too long. A rule of thumb is to transplant seedlings just as the root ball can be easily removed. While times vary, typically plants remain in trays 2 to 4 months.
