Terrafibre Hemp 4 inch Block 6 Pack

Transplant your 1.5" cubes to this block to give the roots the extra space they need. For shorter rotation crops this may be a large enough media or transplant onto the slab or into our loose fill for the remainder of the growth cycle. Blocks have a 1.5" diameter hole in the top and channels along the bottom to increase air flow. Like all Terrafibre products, blocks are fully biodegradable and compostable.
