Perfect medium for hydroponic growing

Spray-N-Grow Gro-Brics are a growing medium made from pure, natural, renewable ground coconut husks. They absorb 5-7 times their weight in water and increase oxygen. They have a neutral pH for use with all plants. Three GroBrics make 1 cu. ft. of growing medium. Use alone or amend soilless mixes to improve water and oxygen retention.
