Product Description
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.
Gro-Blocks are similar to a ‘plant container’. Need a 3” pot? Then choose a 3” Gro-Block. Small plants can be fully grown in our larger Gro-Blocks. Holes are perfect size for any 1.5” starter plug.
