Description

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