Grodan A-OK Plugs 36/40

Grodan A-OK 36/40 1.5 in x 1.5 in Plugs (98/Sheet)

A-OK Starter Plugs for starting seeds and rooting of cuttings prior to plugging into the larger Gro-Blocks. A sheet of A-OK plugs fits a standard 10 x 20 propagation tray (flat).

The 1.5" size work perfectly in the Gro-Smart tray. The advantage of the Gro-Smart tray is it elevates the plugs above the waterline and ensures good airflow around the plugs. A-OK plugs come labeled with instructions in a shrink-wrapped sheet that fits a standard 10 x 20 tray (flat). The 1.5" A-OK fits the opening in all our Grodan Gro-blocks perfectly.

Grodan A-OK plugs are designed for seed and cutting propagation prior to "blocking on" into larger growing blocks. The V-shape design of the plug discourages tangling of roots between the plugs in the A'OK plug sheet.
