A-OK Starter Plugs


Size Price
1.5″ $14.00
2″ $14.00


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).


Delta Starter Blocks

Size in inches
Blocks/Package Usage Example Price
Delta 6.5-Small 4″ 4x4x2½ 6 Tomato/Cucumber $7.50
Delta 10-Large 4″ 4x4x4 6 Plants in large flood trays $16.00



Whether starting your seeds and cuttings in A-OK Starters, Macroplugs, or Mini-Blocks it is a good idea to transplant into a 3” or 4” block. You know it’s time to transplant to the Gro-Block when roots coming out of the starter are about 1” long. Just place your Mini-Block on top of the 3” or 4” with the hole and watch your plant flourish.


Pargo Quick Drain 1.5 Block $12.00

Pargro Quick Drain™ (QD) blocks are up to 14% drier than Cultilene® Comfort blocks. The Jumbo is a particularly good choice when you want to use a big block in an ebb and flow system, as it is 2″ shorter than the Biggie.
