Grodan 6x6x6 Hugo Rockwool Grow Block w/hole

Grodan Hugo rockwool Gro-Block, 6"x6"x5.8", with hole 40/40

Grodan Stonewool (rockwool) is made from molten rock spun into cotton candy-like fibers and then compressed into cubes, blocks, or slabs

-Grodan Delta blocks are the most uniform blocks available on the market

These growing blocks are used for direct sowing or "blocking on" of Macro and Multiblock raised plants

Hugo is the largest of the growing blocks. It provides enough growing volume to support a larger plant, so it does not need to be placed on top of a slab
