Description Grid sold separately. Image shows how the grid sits in the pot. G-Pots have multiple formats of use, provide exceptional value and offer design features that no other drain tray has. G-Pot’s unique tapered design allows maximum air exposure to the entire air pruning pot. G-Pots include a flat, dedicated panel that can be drilled to accommodate 13mm, 19mm & 25mm poly fittings. G-Pots come in two sizes, 480mm (up to 38L/10Gal) and 550mm (up to 76L/20Gal). Both sizes are 150mm/6" high and provide ample volume for drainage and controlled medium flushing. G-Pots can be used by themselves or with a Pot Grid insert for increased drainage and air exposure. G-Pots lock together to form a stable pot stand and drain tray system. G-Pots provide the complete potting solution with the addition of the interlocking trellis (SCROG) kit. With G-Pots the choice is yours.
