What's in the box

  • Twelve 2.4 kg XL grow bags with self-healing injection port
  • Sterility pack — alcohol wipes & face mask
  • Rubber band & paper clips
  • Full-colour step-by-step printed growing manual
  • ❌ Spores / liquid culture — not included (here's why 👇)

Why no syringe? We keep it separate so you can choose exactly which species or strain you want to grow — this kit works with a wide range of varieties. We recommend liquid culture for the most reliable results.

👉 How it works — three simple phases

1. Inoculate (~5 minutes)
Wipe the port, inject your liquid culture or spores, and leave the bag somewhere warm and dark. Hard part done.

2. Colonise (2–6 weeks)
Wait while the mycelium spreads through the bag. A quick break-and-shake at 25% speeds things up, then let it finish.

3. Fruit & harvest (1–2 weeks)
Open it up, add light and cooler temps, and pins appear within days. Harvest, rest the bag, and go again for a second flush.

Every step is covered in detail in the included manual — including a full troubleshooting guide for when things don't go exactly to plan.

🍄 What you can grow

Whether you're growing for the kitchen or for a more personal experience, the CVG substrate in this kit supports a wide range of species — including therapeutic varieties, blue, grey, pink, king and yellow oyster, enoki and pioppino.

(Note: wood-loving species like Lion's Mane, Reishi and Shiitake prefer a hardwood substrate and aren't recommended for this kit.)

Inject & Forget Mushroom Grow Kit Instructions

1. Prep Your SpaceTime to set the stage.

Wash your hands, put on some clean gear, and get that workspace spotless. Shut the windows and doors to keep the air still, and wipe down your working surface. You want everything as clean as possible.

2. Injection

Gloves on, legend. Wipe your gloves down with the skin wipe provided—gotta keep it sterile. Then, grab the green Clinell wipe and clean the injection port and its surroundings. Now, inject 5ml of well-shaken liquid culture or spores. Boom, you’re on your way.

3. Colonisation

Stick that bag in a dark, warm spot—aim for 20-26°C. But hold up—before you think of using a heat mat, check out our blog post. Mycelium typically shows up in about two weeks, but this can vary depending on factors like the spores’ viability, genetics, and temp. Be patient; good things are brewing.

4. Break & Shake

Once you see the mycelium covering 20-30% of the bag, it’s time for action. Gently break up the mycelium and shake the bag to spread it evenly. This move will speed things up massively. Reshape the bag back to its original shape, making sure the surface is nice and flat. Put the rubber band an inch below the substrate line. This will discourage the mushrooms from growing sideways. 

5. Fruiting Time

When the bag’s fully colonized, it’s time to start fruiting. Cut the top of the bag about an inch above the substrate level and place it in the ‘No Mist No Fan’ humidity tent. Fold the top of the tent a couple of times and clip it with the paper clips provided.

No misting needed—this bag’s got all the moisture it needs. The massive breathable filter patch manages airflow while locking in moisture effortlessly. Light it up—12 hours on, 12 hours off works best. A simple, cheap cool white LED light will do the trick.
