Grodan A-OK Starter Plugs 1.5 in

Grodan A-OK Starter Plugs are square stone wool propagation plugs joined at the top into a sheet that drops straight into a standard 10 x 20 tray. Each plug is 1.4 x 1.4 in square (36 x 36 mm) and is offered in 1.6 in and 1.9 in depths. Consistent density, firmness and fibrous structure give every plug the same water and air balance, so germination and rooting stay uniform across the whole sheet.

Built for commercial propagation rooms running manual or automated seeding lines. The firm structure holds up to mechanical handling and the tapered bottom lifts cleanly at transplant into Grodan Gro-Blocks, Max Blocks or Mini-Blocks. Choose a pre-cut hole for cuttings or no hole for direct seeding, in loose plug, unwrapped sheet or shrinkwrapped sheet format.
