Sometimes people cancel their orders, or we simply make "too mush" spawn. So we created these mystery boxes to pass the savings along to you! (Kits are fresh, but may be ready to bust out of their bags. So we recommend growing them as soon as you receive them.)
Our 3-piece mystery fruiting block bundles provide an economical opportunity to grow a lot of mushrooms on a tight budget. Depending on what's available, you may get all of one variety of mushroom or a mix of species.
- Beginner species: Lion’s Mane, Pink Oyster, Blue Oyster, Golden Oyster, Snow Oyster, and Italian Oyster.
- Advanced species: Chestnut, King Trumpet, Black King, Pioppino, and Nameko.

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 blocks 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 can be found under "Temp, Humidity & CO2 guide" on each species page of our fruiting block instruction booklet.
Preparing your block:
Each species has different requirements. Please refer to the species guidelines in our fruiting block instruction booklet.
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.

If you don't plan to use immediately, you can refrigerate your block for up to 6 months.
(Note: DO NOT refrigerate pink oysters -- store them at room temperature for up to 1 month.)

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.
