MycoSphere Frequently Asked Questions

The MycoSphere is the first raised garden bed designed specifically for mushrooms, not veggies or flowers. Its three interchangeable covers and automated misting system let you control light, temperature, humidity, and pests in a way standard beds simply can’t. That means more reliable flushes, higher yields, and fewer failed grows due to unpredictable outdoor conditions.

Yes—MycoSphere is built to handle a wide range of climates, from hot and sunny to cold, windy, or rainy. The shade cloth keeps mushrooms cool and hydrated in intense sun, while the reinforced greenhouse plastic traps warmth and protects your grow in colder or wetter weather. In colder climates, this combination can extend your mushroom season by weeks or even months on both ends. In drier climates, the mister provides much-needed humidity. In warmer climates, you can grow in the MycoSphere year-round.

The bed and frame assemble with basic tools using clearly defined panels and hardware, and the misting system comes pre-cut so you don’t have to measure or chop tubing. The programmable timer lets you “set and forget” simple misting intervals, so you’re not guessing all day. Even if you’re a beginner, the MycoSphere is designed to remove a lot of the trial-and-error that usually makes outdoor mushroom growing intimidating.

You can use it just like a raised mushroom bed for species such as wine caps, or stack logs, buckets, blocks, and totems thanks to the generous vertical space. It’s compatible with many species and methods that already work outdoors, but with much better environmental control. If you want to grow multiple species at once, it pairs especially well with pre-colonized “Plant & Grow” garden blocks.

The automated misting system drastically cuts down on hand-watering, so most of your “maintenance” is just checking that your mushrooms look happy and tweaking the timer if needed. The bug netting keeps out common pests like slugs, beetles, small mammals, and deer, while the thicker covers shield your crop from harsh sun, drying winds, heavy rain, and even moderate snow. Overall, it’s designed to reduce crop loss from both animals and sudden weather swings, so you spend more time harvesting and less time worrying.
