Oyster mushrooms are usually one of the first fruiting blocks that home growers begin with as they are reliable and straightforward to flush. They also produce reliably for multiple flushes, so that you can enjoy your fresh mushrooms up to three times. Oyster mushrooms are well known in the literature to contain significant amounts of protein and B-Vitamins that are essential for health. Le 400 Pieds de Champignon currently offers four different kinds of true oyster mushrooms for cultivation including blue, golden, black pearl and Marie-Anne oyster. For mushroom enthusiasts that are new to growing mushrooms, we highly recommend starting with oyster mushrooms.
Difficulty: Beginner Cold shock: 1 day @ 4°C Fruiting temperature: 17-21°C Duration until pin sets: 5-7 days Duration until harvest: 2-5 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 15 cm sized “X” 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 2-5 days. It is important to maintain a good relative humidity while the mushrooms are developing to ensure soft caps and to prevent the cluster of mushrooms from aborting.
Special notes: One block can produce mushrooms 3-4 times. Once you make an incision on the block, even if you see a mushroom forming elsewhere, keep watering the same incision. When you harvest them, just break them off from the stem and before cooking cut off the bottom. After the first harvest keep watering the same incision. The second and third harvest will be a bit smaller than the first one. If you have any further questions, click here. You can find videos on our facebook and instagram.
