$GBLX Each GrowBLOX™ offers optimal space to support vertical and horizontal growth. Unlike grow tents, grow closets, and other such products on the market, the GrowBLOX’s™ superior height and width produce plants the size of a large bush or a small tree and encourage extensive branching and budding sites to form throughout each plant. This enables each plant to produce from 1 to 1½ pounds of marijuana every eight to twelve weeks. No other product on the market is capable of achieving such an abundant yield per plant indoors.
