Growing characteristics of Golden Teacher

Golden Teacher is known for a controlled and balanced growth cycle. Rather than extremely rapid development, this strain focuses on stability and predictability.

• Uniform development of the mycelium

How do you use the Golden Teacher grow bag?

As the substrate is fully colonised, you can start the fruiting phase straight away. It is important to use a clean working environment and to keep the recommended conditions as stable as possible.

Important: Small slit below the air filter

Below the air filter on the grow bag, there is a small slit made by the manufacturer. This opening allows excess CO₂ and pressure to escape if the grow bag becomes inflated during the growing process. This is normal and is not damage. You do not need to do anything, and the opening should not be sealed or taped.
