What's Inside
Built for the Way
Mushrooms Actually Grow
Controlling growing conditions used to be the exclusive advantage of indoor cultivation. The MycoSphere changes that, giving outdoor growers the same ability to fine tune light, temperature, humidity, and pest pressure that indoor growers have always relied on. Every component is purpose-built to make that level of control practical, consistent, and genuinely beginner-friendly.
Three interchangeable covers, included
Automated misting system
Three Interchangeable Covers
The Bug Net lets in fresh air while keeping out insects and small mammals. The Shade Cloth buffers extreme temperature swings, keeping mushrooms cooler on hot days and warmer on cold nights. The Reinforced Greenhouse Plastic locks in heat and moisture in cooler conditions and shields your bed from heavy rain, wind, and snow. Use them individually or layer any combination to match your climate and season.
Automated Misting System
Consistent humidity is the single biggest variable in outdoor mushroom growing. The MycoSphere's built-in misting system handles it automatically, and the included misting timer lets you fine tune the frequency and duration so your substrate stays at exactly the right moisture level without daily intervention.
Modular Raised Bed Design
The raised bed format works with virtually any growing method: bury Plant & Grow Blocks, stand logs upright, drop in a MushBucket, or build a layered spawn bed. You can even stack logs and buckets to take advantage of the vertical space. One system, endless flexibility.
Extended Growing Season
The MycoSphere's microclimate stretches your season from spring through hard frost. Logs overwintered inside also colonize significantly faster than those left exposed to freezing conditions, so you get to harvest before the season ends (and before the deer do).
