Bolles Bear's Head - Hericium americanum mushroom block
Difficulty: Beginner Cold shock: 1 day @ 4°C Fruiting temperature: 17-21°C Duration until pin sets: 7-14 days Duration until harvest:5-10 days Humidity: 90%
1)When ready to fruit, place the fruiting block in a refrigerator for 24 hours at 4°C. This will send signals to the mycelium fruiting block that it is time to reproduce by forming mushrooms Using a sharp knife, cut a 3cm sized slit into the side of the mushroom block and remove any extra air that may be trapped inside the back by folding the bag onto itself.
2)Spray the surface of the exposed mushroom block 2-3 times a day to maintain a high humidity until small ‘pins’ start to form.
3)When you observe small tiny mushrooms growing, they will be ready to harvest within 5-10 days. It is important to maintain a good relative humidity while the mushrooms are developing and to prevent the cluster of mushrooms from aborting.
