A-Ok Starter Plugs™ are for starting seeds and rooting cuttings prior to plugging into larger Gro-Blocks™.
The 1.5” size fits perfectly in the Gro-Smart tray as well as all our pre-drilled Gro-Blocks.
One advantage of using the Gro-Smart tray is that 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 package that fits a standard 10 x 20 tray (flat).
