G2G 1.5″ Rockwool Plugs

The G2G Rockwool 1.5” Propagation Plugs are for starting seeds and root cuttings prior to transplanting into the G2G Rockwool 6” Cube. The rockwool plugs fit perfectly into the 1.5” diameter hole included in the 6” cube. Each plug has a uniform density, firmness and fibrous structure resulting in a uniform distribution of water, nutrients and pH levels.
