Fertilome Horticultural Vermiculite

ferti•lome® Vermiculite is the mineral Mica, super-heated to expand much like an accordion.
This mineral is also used in soil mixes to increase water-holding capacity.
Many growers use vermiculite in their flats in order to create a microenvironment that will protect seeds from air currents and insulate the seeds to provide uniform germination temperatures.
