What Size Syringe Do I need?

Our bags have a max amount of moisture they can hold, therefore it's important to check how much you need prior to setting up your project! These bags are purpose-made for Gourmet Health Mushroom spores and should be used alongside a bag sealer (for contamination-free second and third harvests) as well as a heat mat or heat chamber to keep the temperatures constant. Please refer to the table below for this information!

We cannot be held liable for any illegal use of these spores. Please check your local regulations as we cannot be responsible for the laws you should follow in your own country.

Description

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

Your chosen amount of agricultural gypsum (Calcium Sulphate) carefully packaged to prevent spillages.
