Agricultural Gypsum

Agricultural gypsum is another name for Calcium Sulphate. This comes from our warehouse, straight to your door in a convenient, ready to use format. I’s available from 100g to 5000g.

Gypsum is the common name for calcium sulfate (CaSO4). It is a grey powder used for making cement and drywall. Gypsum is used in grain spawn to prevent kernels from sticking together. It’s also used as a pH-buffer and lightening agent in bulk substrate and casing material preparation.

We advise you use it at a guide rate of 2-5% dry substrate weight. Using this as a PH-Buffer will allow for more flushes from your substrate!

What You Will Receive
