How your first harvest works
Using the Fresh Mushroom Box as an example:
- Open: Remove the window, cut an “X” into the bag and lightly scratch the mycelium.
- Place: Bright but out of direct sun – not next to a radiator and not in a draught.
- Mist: Spray water behind the flaps twice a day.
- Harvest: The first mushrooms appear after about 2 weeks, 4–5 days later they are ready.
Every product comes with a step-by-step guide – also via the QR code on the label.
FAQ: mushroom growing kits
Do I need experience or special equipment?
No. The Fresh Mushroom Box is fully prepared; for the Home Mushroom Growing Kit you only need hot water and clean hands. The guide takes you through every step.
When can I harvest the first mushrooms?
With the Fresh Mushroom Box after about 3 weeks. With the Home Mushroom Growing Kit the spawn first colonises the substrate for about 4 weeks, then the mushrooms form within a few days.
Where should I place my kit?
In a bright spot out of direct sun, e.g. kitchen or bathroom. Important: no radiator nearby and no draught. Mushrooms love humid air.
How many times can I harvest?
The Fresh Mushroom Box usually gives a second flush after the first harvest. With the Home Mushroom Growing Kit 2–4 flushes per bag are typical.
Do the kits make a good gift?
Yes. The Fresh Mushroom Box keeps 3 months at room temperature. For the Home Mushroom Growing Kit, keep the spawn in the fridge until you start (approx. 3 months). Vouchers for our mushroom growing courses are available too.
What do I do with the substrate after harvesting?
The spent substrate is a valuable organic fertiliser – put it on your compost or raised bed.
What if nothing grows?
Usually the air is too dry or the spot too warm. Check the guide or send us a photo. The Fresh Mushroom Box comes with our harvest guarantee: harvest or your money back.
