Horticultural Mixes.
Therm-O-Rock East produces a line of high quality soilless growing media under the brand name “PRIME GRO”. Private label horticultural blends and packaging are also available. Prime Gro is available under three general purpose horticultural mixes: Peat light -- Peat bark -- Peat wool. We also will custom blend horticultural mixes to meet specific needs. We do not produce to inventory but to order. That insures the freshness of every order that is shipped.
