A-Ok Starter Plugs™ are for starting seeds and rooting cuttings prior to plugging into larger GRO-BLOCKS™.
A-Ok plugs come labeled with instructions in a shrink-wrapped sheet that fits a standard 10 x 20 tray (flat).
The 1.5” size fits holes in all our GRO-BLOCKS™ and work perfectly in the GRO-SMART™ tray.
Using our A-Ok Starter Plugs™ with the GRO-SMART™ tray (sold separately) provides many advantages as it elevates the plugs above the waterline and ensures good airflow around the plugs.
