Vermiculite Fine Grade Horticultural Organic Vermiculite - 4 Cu Ft Bag

Looser Media That Holds Moisture and Air - 4 Cu Ft Bag

Compacted media makes it hard for roots to spread and breathe. Fine grade horticultural organic vermiculite keeps soil from clumping, holds moisture and nutrients for later use, and lets air reach the root zone. It is also sterile, so you start without bacterial or fungal worries from the medium itself.

This 4 cu ft bag is sold each. It suits regular indoor growers, small-area gardeners and hydroponic setups that blend their own media and want enough material for several batches.

Who Should Use Vermiculite Fine Grade Horticultural Vermiculite

Frequently Asked Questions

A: It holds moisture and nutrients and keeps the mix from clumping. That leaves more air around the roots.
