Therm-O-Rock® Horticultural Vermiculite4cu ft - Medium - OMRI Listed®Therm-O-Rock® Vermiculite is a versatile soil additive valued for its ability to retain water, improve aeration, and prolong nutrient release through its unique accordion-like particle structure.

Ideal for conditioning container soils, vermiculite helps create a balanced growing environment by holding both air and moisture.

It can also be used for seed germination, bulb storage, and flower arranging.

Made from a hydrous phyllosilicate mineral that expands dramatically when heated, the finished product resembles small, shiny gold or light brown popcorn-like pieces.

Vermiculite is prized for being inert, heat resistant, and highly effective at moisture retention.
