TERRAFIBRE HEMP FIBRE GROW BLOCK 4in. (6 CUBES)

TERRAFIBRE HEMP FIBRE GROW BLOCK 4in. (6 CUBES): Transplant your 1.5” Terrafibre Grow Cubes into this block to give the roots the extra space they need. For shorter rotation crops this may be a large enough media to fulfill your growing needs; or transplant onto our Terrafibre Grow Slab for the remainder of the growth cycle. Blocks have a 1.5” diameter hole on the top and channels along the bottom to increase air flow.
