Harvest the mushrooms by picking of or cutting off entire clusters. Picking older mushrooms will improve the yield, but risks covering your grow room with spores or picking the mushroom past their prime for culinary use. Grow bags work by cutting slits in the side of the bag for mushrooms to grow through, or simply by cutting off the top of the bag and allowing fruits to form on the top of the block.īlue Oyster mushrooms are incredibly versatile and can be also grown in 5 gallon buckets with holes drilled, or any container you can think of.īlue Oyster Mushrooms can achieve extremely high yields, up to 200% biological efficiency. Too thick a straw log will cause the center of the log to become anaerobic and eventually contaminate. Use poly tubing for straw logs, 16″ lay flat diameter. Supplemented sawdust blocks also work quite well, but straw is likely to produce similar results more economically.īlue Oyster mushrooms will devour almost anything and can even be grown on coffee grounds, waste paper, sugar cane, grass and many other waste industrial products.

Straw logs will produce multiple flushes if contamination can be kept at bay. Use a higher spawn rate for better yields. Pasteurized straw logs are extremely effective for Blue Oyster mushrooms. Try to position your spawn so that grain is not sitting soaking in water when colonizing,Ī close up of the gills of the Blue Oyster Mushroom. Easily broken up through shaken for no fuss spawning to bulk substrates.īlue Oyster spawn has a tendency to sweat, producing pockets of water in your spawn bags or grain jars. Oyster spawn has a unique mushroomy scent. Some report higher yields on straw if sawdust spawn is used in lieu of grain spawn. Rye grain works best, but sawdust spawn can also be used. Growth can be rhizomorphic and eventually gets thick and fluffy.īlue Oyster mycelium has a tendency to emit a brown/orange metabolite, which can often be mistaken for contamination, although it could be a sign that the mycelium is fighting off contamination. Difficulty of Cultivation:īlue Oyster mushrooms grow vigorously on Agar. They seem to prefer malt yeast agar. The Long Stems indicate high CO2, Natural Habitat:įound on hardwood logs trees and stumps, living, dying and decaying.
