Gypsum is used at almost every stage of mushroom cultivation, adding essential minerals and trace elements to bulk substrates or grain, aiding in mushroom development and increasing yields.

Hand-Packed with ❤ in Bristol, UK.

Our powdered Gypsum can be added to soak or boil water at grain preparation stage or direct to substrate as a nutritional supplement. Is also commonly used to stabilise the PH of substrates, preventing wild swings. Gypsum has a natural PH of 7 (neutral).

Can be added up to 5% of dry weight of substrate or grain, recommended 2-3%.

    Used extensively in almost all stages of mushroom production to give essential nutrients to mycelial growth. A safe nutritional supplement for beginners which has noticeable effects if compared to grows without. Good price when ordered in bulk. ~ Han
