How It Works

Innoculate
Use sterile technique to inject liquid culture into the sterilised grain jar.
Incubate
Store inoculated grain in a clean environment at the correct strain temperature. Allow full colonisation before next step.
Substrate
When grain is fully colonised, break it up and mix evenly through the sterilised Master’s Mix grow bag. Seal and keep warm.
Fruiting
Once colonised, start fruiting by cutting slits in the bag as directed, allow fresh air exchange, humidity, and light misting until pins and mushrooms develop.

FAQ

Do I need a pressure cooker?

No. Everything in this kit is pre-sterilised and ready to use. The rye grain and Master’s Mix substrate have already been sterilised, and the injection port lid allows you to inoculate without open-air exposure. No pressure cooker or specialist lab equipment is required.

What temperature should I keep it at?

Most gourmet species grow well at normal room temperature (around 20–24°C). Keep the jar and bag in a clean space away from direct sunlight. Once fully colonised, slightly cooler temperatures and fresh air help encourage fruiting.

Is this suitable for beginners?

Yes. This kit is designed specifically to reduce common beginner mistakes. The step-by-step workflow (grain → substrate → fruiting) helps minimise contamination risk and simplifies the growing process. If you can follow basic instructions, you can grow with this kit.

Can I choose my mushroom type?

Yes. You can select your preferred gourmet species from the dropdown menu when ordering. The kit works especially well with oysters, lion’s mane and other hardwood-loving gourmet mushrooms.
