Vermiculite Medium Grade - 12 Qt Bag

Looser Mix, Steadier Root Moisture - 12 Qt Bag

Dense, clumping mixes starve roots of air and dry out unevenly. Horticultural vermiculite keeps a mix open, holds moisture and nutrients for later use, and lets roots take up oxygen. It is sterile and odorless, so it adds no bacterial or fungal load to your root zone.

The 12 Qt bag is a practical size for small gardens, trial blends and growers who mix their own media in modest batches. Larger operations can order multiple bags, subject to the order minimum.
