Gro-Blocks™ are similar to a ‘plant container’.
Need a 3” pot? Then choose a 3” Gro-Block.
Plants can be fully grown in our Gro-Blocks, for larger plants try Hugo or Big Mama our two giant sizes.
Gro-Block holes are the perfect size for any 1.5” starter plug or Macroplug.
The bases of the Gro-Blocks are grooved to promote drainage and to avoid “wet feet”.
Gro-Blocks™ comes in strips labeled with instructions.
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.
