Bio Austernpilz-Zuchtkit Fruchtungsblock

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!

Fruiting blocks should be used within 1 week of receipt. If you don't plan to use immediately, you can refrigerate your block for up to 6 months.

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.

Pro tips:

• 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.

Special considerations:

• 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!

Troubleshooting:

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.
