Our Pearl Oyster All in One Grow Bag pairs a 1.5kg all in one grow bag with a 10ml Pearl Oyster liquid culture syringe, so you have everything needed to grow pearl oyster (Pleurotus ostreatus) at home in one simple bundle. Buying them together costs £3.99 less than buying the bag and culture separately.
What is included
- 1.5kg all in one grow bag filled with sterilised millet, milo grain and CVG substrate
- Self healing injection port and microporous filter patch
- 10ml Pearl Oyster liquid culture syringe
- Sterile 16G needle and 70% IPA swab
How to grow pearl oyster
- Wipe the injection port with the IPA swab, fit the needle and inject 3 to 5ml of liquid culture.
- Incubate the bag somewhere dark and warm, ideally 20 to 25°C.
- When the grain is around 30% colonised, gently break it up and mix it through the substrate to speed things along.
- Once the bag is fully white with mycelium, move it into fruiting conditions at 10 to 18°C with high humidity, fresh air and indirect light, then cut a small opening for the mushrooms to grow from.
About Pearl Oyster
Pearl oyster is the classic oyster mushroom, with cream to soft grey caps and dependable, heavy flushes. It tolerates the odd beginner mistake better than almost anything else. Expect several flushes from one bag if you keep humidity high between harvests. We rate this bundle as intermediate level.
Pair your bag with a fruiting tent to hold humidity, and keep gloves and alcohol wipes to hand for a clean inoculation. You can also browse our full range of mushroom liquid cultures and mushroom grow kits.
Store the liquid culture in the fridge at 2 to 8°C until you are ready to use it, and inoculate the grow bag within a few weeks of arrival.
