Organic Snow Oyster Mushroom Grow Kit Fruiting Block
|Grow speed||1 to 2 weeks|
|Shelf life||6 months (refrigerated)|
|Kit dimensions||6in H x 9in W x 6in D|
|Kit weight||5 lbs|
Our snow oyster (Pleurotus ostreatus) fruiting block features a strain that produces beautiful clusters of fleshy, firm white to cream-colored caps. When cooked, they have a milder, sweeter flavor and aroma and hold their shape and texture better than other oyster varieties.
Snow oyster mushrooms thrive in cooler temperatures and are great for beginners as they are reliable producers and tend to grow large flushes. They are also one of the easiest blocks to get subsequent fruitings and, if kept in the right conditions, should reliably produce a second flush or more!

Upon receiving your kit:
Remove kit from the shipping box as soon as possible. Then, unfold the top of the bag, making room for air space. It's also important to check and confirm that the filter patch is not obstructed. This will help the organism breathe and continue to thrive until you are ready to grow your fruiting block!

For the majority of mushroom species, all that is needed to initiate fruiting (or begin the growth cycle) is a change in environmental conditions -- specifically humidity, light, temperature, and changes to oxygen and CO2 levels.
For best results:
We recommend growing your snow oyster block in a fruiting chamber (like a monotub or martha tent) as a controlled environment will decrease the risk of contamination and increase the chances of success.
Creating optimal conditions:
The environmental parameters for snow oyster mushrooms can be found on this page under "Temp, Humidity & CO2 guide" and on page 7 of our fruiting block instruction booklet.
Preparing your block:
Tightly fold excess plastic back and place the block face up.
How to initiate fruiting:
- Slice bag with a single diagonal line or with an X.
- Snow oyster mushrooms can be top or side fruited.
- Snow oysters like it cold, below 65°F, throughout pinning and fruiting. To get temps down in your fruiting chamber, fill the bottom of a small, insulated, uncovered box with ice cubes and sit the snow oyster fruiting block on top. Then place the box back into the fruiting chamber. Replace ice cubes daily.
- Snow oysters need high humidity during the pinning phase. To get the high humidity required during the pinning phase without creating water accumulation in your fruiting chamber, use a spray bottle twice a day to supplement the fruiting chamber humidity. By doing this, you won't have to run the humidifier as high.
- Snow oyster mushrooms are not heat tolerant and require cooler temperatures to fruit.
- Snow oyster mushrooms are prone to discoloration and/or blotch (dark spots on the fruiting bodies) when grown in warmer temperatures.
Harvesting your mushrooms:
Harvest snow oyster mushrooms when edges of cap are still slightly turned under. Remove clusters with care as caps can be brittle. Can be harvested young to extend shelf life.
Growing different blocks together:
With some compromise, many different species of mushrooms can be grown together in a fruiting chamber. First, consider the temperature range of the mushrooms you desire to grow, and second, the CO2 sensitivity. Humidity ranges overlap for the majority of species. We encourage you to experiment with many different groupings!
Having issues with unusual growth, stunted growth, or no growth at all? Refer to pages 16-18 in our fruiting block instruction booklet.
Temperature 45-65°F | 7-18°C Humidity (Phase 1: Primordia) 95-100% Humidity (Phase 2: Fruitbody) 85-95% CO2 Sensitivity (Phase 1: Primordia) <1,000 ppm CO2 Sensitivity (Phase 2: Fruitbody) <1,000 ppm
- Primordia - The earliest recognizable stage of fruitbody development. Also known as “baby mushrooms” or “mushroom pins.”
- Fruitbody - A fully grown mushroom, the reproductive structure of the organism in which the spores are produced.
- CO2 sensitivity - When CO2 levels are too high, yields will decrease, stems will become long and stringy, caps will be small, and/or growth will halt.
If you don't plan to use immediately, you can refrigerate your block for up to 6 months.

The classic North Spore recipe is to slice up oyster mushrooms and sauté them in a heavy pan on medium heat with butter, garlic, and loads of fresh thyme and rosemary (or whatever other herbs you happen to have on hand!) Cook until the mushrooms have released their liquid, then continue cooking until that liquid has cooked off and the mushrooms begin to brown. Deglaze your pan with a splash of white wine, reduce once more, and finish with a touch of heavy cream. Season generously with salt.
Like all Oyster mushrooms, they retain water and may develop a viscous texture when under-cooked. If you prefer a firm or dryer texture, continue to cook Oysters until their liquid has reduced and cooked off and they begin to brown.
If you’re going to consume home-grown mushrooms, make sure to cook your fresh mushrooms thoroughly with heat. If it is your first time eating this species, it is best to start with a small amount to check for allergies, even if cooked.
Mushrooms grow spores as they develop. This is a natural means of reproduction. This is when people with allergies or compromised immune systems may want to consider putting fruiting mushroom kits outdoors or in a well-ventilated area. Spores in mushrooms sometimes cause respiratory irritation. In rare cases, spores may also cause irritation for some non-allergic or non-immunocompromised mushroom growers. If you are one of them, it is recommended to reduce the overall spore load by harvesting mushrooms while they are still in their younger growth stages.

The block arrived in great shape. It fruited quickly and I got over 18 oz of mushrooms. Cooked them up last night, delicious! Looking forward to a second fruiting.
Savior Customer Support
I had ordered snow mushrooms which did not fruit possibly due to shipping issues, but I called in and explained what happened and was sent a replacement which has been fruiting for weeks now. Excellent response and customer service!
Beautiful Snowy wonderland
Harvested in 6 days after opening the bag, very nice and tasty! Over 1 pound harvest
Simple with great results
I just harvested my first flush this morning and got 15.5 ounces. Not a bad haul. In my inexperience I let the shrooms mature a little too much and drop spores. Little clean up but not a big pain. Highly recommend this product. Interested to try for secondary flushes
Snow oysters for winter
Very easy and fun! Also took no time to grow! I was eating them within 1.5 weeks!! Threw them in my vegetarian pho and it was so delicious!
