Grodan Grow Blocks and Cubes

Macroplugs have a slit that allows for easy insertion of a cutting or bare-root plant.These round plugs fit perfectly into the Gro-Blocks™.
 
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 package that fits a standard 10 x 20 tray (flat).
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” block without the hole, or your Macroplug/A-OK into the 3” or 4” block with the hole and watch your plant flourish.
