    Grodan's RW103702W Pargro Quick Drain blocks are the perfect size for you to place a 1.5-inch round starter plug, macro-plug, or mini-block. When seedling roots have grown one inch long from the bottom of your starter plug, simply transplant the plug into this 4 x 4 x 4 inch block. It can then be placed on top of a grow slab to provide for a larger growing volume if desired. This is the most affordable horticultural rockwool on the market with its compressed fibers and improved grooved base to promote superior drainage. Quick Drain blocks are sold in strips of six, 12 strips per case and labeled with instructions.
