How to grow oyster mushrooms at home
Mix
Disinfect the Growkit and the lid. Mix the contents of the spawnbag with fresh coffee grounds. Close the kit.
Fill
When the coffee is covered in white, add new coffee. Repeat until the Growkit is full.
Harvest
When the mushrooms push through the tape, mist them frequently for 4-7 days. Harvest by turning the whole cluster.
Mushroom growing is pretty simple!
You only need fresh grounds from your morning coffee and a Helsieni Growkit. The kit includes a growing box, breathable tape and some spawn. If you already have a container suitable for growing the Helsieni Starter Kit is for you. This mushroom is suitable to grow indoors and converts coffee grounds into tasty oyster mushrooms!
