Therm-O-Rock® Vermiculite

Super Coarse #1X

Therm-O-Rock® Vermiculite is a soil additive that uses its accordion-like particles to amend soil by retaining water, improving aeration and prolonging nutrient release. Its ability to retain both air and water makes vermiculite ideal for conditioning container soils. Vermiculite can also be used for seed germination, bulb storage and flower arranging.
