Description

Grodan 4″x4″x4″ cube large hole box of 144 blocks

This is the most popular size rockwool cube. 4 x 4 x 4 inch Growing Blocks with holes for smaller cubes. Used as a second stage from smaller cubes. The 1-1/2 inch hole will accept the small cubes that come in a sheet or the wrapped cubes that come in a strip. Growing blocks are great for ebb and flow hydroponic systems or for use as mid stage for plants eventually going on to Rockwool slabs. The blocks are individually wrapped in plastic on four sides to hold moisture and stop alga growth. The base of each block is grooved for drainage. Blocks are supplied in 24 inch long tear away strips. Case of 144.

Growblocks are used for direct sowing or “blocking on” of Multiblock and Miniblock raised plants. Just root or sprout in the smaller blocks and transplant into larger blocks once the roots begin to become exposed and the plants will root right into the larger blocks. The blocks are individually wrapped in UV resistant white plastic on four sides and supplied in convenient tear away strips. The base of the Growblocks are grooved to promote uniform and complete drainage preventing the occurrence of root rot. If the plant begins to become root bound in one of these Growblocks you can either place the block right on top of a slab and let the plant root into the slab, or you can stack the cubes on top of each other. These come in a wide variety of sizes ranging from 3″ side to 4″ wide and up to 4″ tall. These Growblocks work excellent in all ebb and flow or drip hydroponic systems. All Growblocks are sold in packages containing strips of blocks which vary in the amount of blocks according to the size of the Growblock.
