ABSTRACT:
The present invention entails a plant growing tray system which includes a tray with a plurality of individual plant cells having an open top and bottom and a detachable screen or perforated bottom. Each tray cell is designed to contain and hold a plant growing medium such as peat cake or peat-soil mix. A detachable bottom secured to the bottom part of the plant tray provides air-pruning of plant roots and can be conveniently removed from the plant tray for easy removal of the individual plants or seedlings from the tray bottom. Air-pruning of plant roots eliminates root binding or tangling and accelerates root branching resulting in enhanced plant growth in the cell or after transplanting.
The plant tray has a surrounding edge to hold a water level above the top of the tray cell or micro-feeding holes of each cell for self watering and to maintain uniform root zone temperature throughout the tray. The detachable screen or perforated bottom can be press fitted to the tray bottom to hold the peat mix and to provide effective air-pruning of the plant roots.
