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

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).

MycoSphere Frequently Asked Questions

The MycoSphere combines the simplicity of a raised bed with the protection and moisture control growers usually look for in a more complex setup. Its interchangeable covers and built-in misting system help you manage humidity, airflow, light exposure, and pest pressure more effectively than a standard garden bed, while staying simpler and more flexible than a traditional greenhouse.

The MycoSphere is designed for outdoor mushroom cultivation, but it also works well for vegetables, herbs, greens, and other garden plants that benefit from more consistent moisture and protection from the elements. It’s a strong fit for mushroom beds, logs, totems, buckets, blocks, and Plant & Grow starters, while also giving gardeners a protected outdoor growing space.

Yes! MycoSphere is built for a wide range of outdoor conditions. The shade cloth helps reduce heat and sun stress, the greenhouse cover adds warmth and weather protection, and the misting system helps maintain moisture in drier conditions. Together, those features can help growers in many climates create a more stable environment and extend their usable outdoor growing window.

The system is designed to be approachable for beginners. The bed and frame assemble with basic tools, the misting components come pre-cut, and the timer helps automate watering intervals so you are not managing moisture by hand all day.

The automated misting system drastically cuts down on hand-watering, so most of your “maintenance” is just checking that your mushrooms or plants 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.
