Root-Gyp Powder is a ground powder produced from the processing of Gypsum mineral, Calcium Sulphate Dihydrate (CaS04.2H20) which is highly soluble and pH neutral. The product is manufactured from a naturally occurring mineral and therefore variations in colour and non-gypsum content are to be expected.

Gypsum is widely used within the production of compost, particularly the production of compost supplied to the mushroom growing industry. The properties within Gypsum help to flocculate the grease matter within the process and also adjust the pH levels.

Product available in 25kg or 1 tonne bags.
