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.

Inject and Forget Mushroom Grow Bag (4lb) – Easy Gourmet Mushroom Cultivation

Our best selling Inject and Forget Bags are the simplest way to cultivate
Gourmet Health Mushrooms at home. Designed for beginners and experienced
growers alike, these 4lb bags are easy to use, protected from contamination, and capable of
delivering multiple flushes.

We recommend using 20ml of Gourmet Health Mushroom spores per 4lb bag.
Spores are not included.

Why Choose This Kit?

  • Easy to Use: Inoculate, place upright in a warm spot, and wait until harvest.
  • Contamination Protection: No misting or fanning required, reducing risks.
  • Perfect for Beginners: Straightforward instructions with minimal maintenance.
  • Quick Results: Fully colonised in 2–3 weeks, harvests in 35–45 days.
  • Multiple Flushes: Expect 2–3 harvests with simple rehydration steps.

How to Get Started

  1. Prepare your workspace – wipe down with 70% isopropyl alcohol spray.
  2. Set up your heat source – maintain 26–27°C. Our 60L incubators come pre set.
  3. Wash your hands and remove the bag from its protective cover without touching the air filter.
  4. Prepare your syringe – attach the sterile gamma irradiated needle and shake gently.
  5. Sanitise the injection port with the provided alcohol swab and let it dry.
  6. Inoculate – insert the needle halfway at a downward angle and release spores into the bag.
  7. Incubate upright in low, indirect light. Once mycelium appears (size of a 50p coin), gently mix the bag.

Harvesting

When pins begin to form, your Gourmet Health Mushrooms are nearly ready.
Harvest between stage 3–4 (before caps open and release spores) to prevent contamination
and maintain strong yields.

Repeat Flushes

Each bag can produce 2–3 flushes. To trigger another harvest:

  1. After the first flush, add one cup of cold water to the bag and leave sealed for 12 hours.
  2. Drain the water slowly over 30 minutes.
  3. Return the bag to the same growing conditions and wait 7–14 days for new mushrooms to appear.

What’s Included

  • 1× 4lb Inject and Forget Bag
  • 1× Alcohol swab (for the injection port)

Spores not included – sold separately.

Important: It is illegal to grow magic mushrooms in the UK.
Our spores are sold strictly for microscopy and research purposes only.
Always check your local laws – Shiny Spores cannot be held liable for illegal use.
