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 : Delta 10 Large 4"
- Sizes in inches : 4x4x4
- Hole size: Big
