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.

Quick Drain Biggie is large enough to grow out most vegetables and some fruits for the entire lifespan of the plant. It features the driest rockwool on the market and a 1.5-inch hole to place a starter plug perfectly.

When your starter plug has outgrown its home, showing three leaves, or roots reaching one inch below the cube, the Biggie block is happy to receive the transplant. Quick Drain Biggie is sold by the case with instructions on the wrapping. Hand water or use with drippers or in Ebb and Flow (Flood) systems.
