The quickest, easiest, most reliable mushroom kit we've ever seen!

With this handy kit you'll soon be picking delicious fresh mushrooms straight from the windowsill, at a fraction of the cost of buying them at the supermarket. Kit comprises base tray, lid and pre-spawned substrate.

Dimensions: 17.5cm (7") x 27.5cm (11") x 8cm (3½") depth.

Full growing instructions included.

Always wash your hands before you handle any of the kits to avoid bacteria contaminating the substrates and development of other moulds.

The kit contains a base tray, plastic lid and a plastic bag with a substrate of sawdust.
If you see any white/brown bumpy growths, these indicate early mushroom fruition. These bumps will later become the shiitake mushrooms.

1. Cultivation: Remove the substrate from the plastic bag and immerse the substrate in a bucket filled with cold tap-water for 24 hours. Lay a heavy object on top of the substrate to keep it under water. After 24 hours place substrate in the tray and cover with transparent lid.
Please note: if mushrooms are already growing on the substrate, you may skip the immersion step.

2. Place kit in daylight, ideally on a windowsill facing north at a temperature of + 15°C. Wait until + 50% of the surface has turned brown. During this time, keep the kit covered with the transparent lid.

3. Spray the cultivation substrate at least once a day with a plant spray to prevent it from drying out. 

4. Harvesting: The harvest period is around one week and the fully-grown mushrooms have a cap diameter of 4–8cm.

5. After a harvest, let the substrate rest for at least 15 days. During this rest period, take the kit from the windowsill and keep it in a place which is neither too dry, or too hot (a cellar is ideal).

6. After this period, repeat the cycle, starting at point 2. The second harvesting period arrives after 5–10 days. During a period of maximum 6 months, you may have 5 to 8 harvests.

Good Luck & Bon Appetit !
