Golden Oyster Kit


Grow Your Own Golden Oyster Mushroom Kit

Temperature Range: 60-80F

Skill Level: Novice

Product Description

Our GYO kits are a mycological kitchen-countertop-science-experiment, perfect for foodies, gourmands, epicures, locavores, vegans, paleo health-conscious cousins, nature lovers, show-and-tell grade-schoolers and as hard-to-please hostess gifts. It requires no more commitment than a house plant. Several harvests will occur over a period of 6-8 weeks, yielding up to 4 pounds of Golden Oyster Mushrooms from one kit. Our kits need indirect sunlight to grow to their full potential, and prefer a temperature range of 60-80 degrees F, but they are also pretty easy going and user friendly. Mushrooms have been doing their thing on earth for a long time.

Instructions will be provided on misting, fruiting, harvesting, storage and preparation of your mushrooms. Our website has tips, recipes and frequently asked questions. After the kit has ceased production, it can be removed from the bag, broken up and added to garden soil or a compost pile.

Thank you for eating locally (it doesn’t get more local than growing in your own kitchen) and for supporting Pennsylvania farmers.

Our family wishes you good health!

PLEASE NOTE: All kits are made to order and may take 7-10 days to ship.




Place your GYO Oyster Mushroom Kit on a plate or pie tin in a location with indirect sunlight. Oyster mushrooms require some exposure to sunlight. DO NOT remove from bag.

Begin misting the entire surface of the kit as well as the plate at least 3-5 times per day. More misting is always beneficial. Chlorinated or distilled water are not recommended for misting your kit. We recommend spring, well, or rainwater.

Tiny primordia (baby mushrooms) will begin to appear 3-4 weeks from the date written on your kit. Mushrooms should form at the pre-cut holes, but may form where there are no holes in the plastic. If this happens, use scissors or a razor blade to carefully cut a hole around the forming mushrooms. Continue misting at least 3 times per day, and also directly mist the forming mushrooms.


Mushrooms grow quickly and can mature in 3-7 days. Harvest your mushrooms as the caps begin to flatten out, but are still mostly turned down. Some mushrooms may appear smaller than others even when fully mature. Harvest your mushrooms by gently twisting the clusters at the base. Continue to mist your kit daily, and you can expect a second flush of mushrooms within 2 weeks. If kept properly hydrated, 3-4 flushes of mushrooms are possible, with each flush yielding slightly less.


Store your mushrooms in the refrigerator in a paper bag or in an open container covered with a paper towel. Do not store them in any type of closed plastic container or plastic bag. This will cause premature spoilage.


Trim the stems and sauté on medium-high heat with butter or olive oil, minced garlic and salt and pepper, until golden brown. Serve on top of pasta, steaks, or add to sauces or stir-fry. Save the stems as they can be used to make a flavorful stock.


Q: What’s in this bag?
A: Your grow kit contains locally-grown wheat straw, and oyster mushroom mycelium grown on rye grain.

Q: Should I take my kit out of the bag?
A: No. The bag holds the kit together and the plastic keeps it hydrated.

Q: What is this dust coming off of my kit?
A: The grayish-purple “dust” you might see coasting out from under mature mushrooms is actually spores. The mushrooms have reached their next reproductive phase and are sporulating. It means your mushrooms are ready to harvest.

Q: I’ve been misting dutifully, but nothing is happening. What should I do?
A: Keep misting, the mushrooms are waiting to surprise you. As long as your kit is still hydrated, and the mycelium and straw mixture doesn’t show any discoloration, it’s still growing just fine. If it’s been more than 4 weeks and no mushrooms are growing, your kit may be dehydrated. Submerging the entire bag in cold water for 24 hours will rehydrate the kit, and usually cause new mushrooms to form.

Q: How long will my harvest keep in the fridge?
A: Freshly harvested mushrooms will keep well up to a week or more when refrigerated. Keep them in a paper bag, or covered with a paper towel. Sealing them in plastic will cause them to get soggy and accelerate spoilage.

Q: What should I do with my harvest?
A: Butter. Saute them in butter, with white wine and minced shallots or garlic, but mostly butter. The fat and salt enhance the flavor tremendously. If butter’s not your thing, use your cooking oil of choice.

Q: Should I eat my mushrooms raw?
A: We recommend cooking them. They taste better and are actually more bio-available and nutritious for you after they have been cooked. Mushrooms cell walls are made of chitin, which our stomach cannot breakdown. Cooking dissolves the cell walls making the nutrients available to our bodies.

Q: Should I grow my kit outside? Or in the dark?
A: We recommend growing it inside. The mycelium in the kit smells sweet to insects and mites. Growing indoors will prevent your hard earned harvest from getting nibbled by them. We also recommend kits be placed in indirect sunlight. The more light they get, the deeper the cap color will be. Direct sunlight is too strong and may dry them out.
