Rockwool 4" Block Case of 216

Regular price Price: $174.95 CAD Sale

When starting your seeds and cuttings in Plugs, 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 bigger block when roots coming out of the starter are about 1” long. Just place your plug into the 3” or 4” block with the hole and watch your plant flourish.
