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!

Disclaimer

Please note that it is illegal to grow magic mushrooms within the UK. We ask that you do not use these spores to grow mushrooms, but instead use them to study under a microscope. 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.
