MycoClimate™ 66Q Automated Monotub Mushroom Grow Kit – Temperature & Fresh Air Control

The MycoClimate™ 66Q Automated Monotub Mushroom Grow Kit is built for growers who want greater control over the conditions inside their cultivation chamber. This larger-capacity system introduces regulated warmth and continuous fresh air exchange, helping maintain an environment that supports healthy mushroom development.

With expanded growing space and increased substrate volume, the 66-quart system is ideal for growers looking to produce larger flushes while maintaining stable temperature and airflow throughout the grow cycle.

At the heart of the MycoClimate™ design is a two-layer monotub structure that forms a shallow water reservoir beneath the growing chamber. A digital aquarium heater warms this reservoir, producing gentle radiant heat that surrounds the grow chamber evenly. This approach avoids the hot spots common with traditional heat mats while helping maintain substrate moisture.

The kit also incorporates an active air exchange system. A quiet electric pump pushes filtered air through a silicone hose equipped with a built-in HEPA filter, continuously introducing oxygen while reducing stale air buildup inside the tub.

Combined with a full-spectrum LED grow light, programmable timer, premium grain spawn, and Midwest’s trusted bulk substrate blend, the MycoClimate™ system delivers a complete setup designed to streamline the cultivation process from start to finish.

Simply inoculate the included spawn bags using your preferred spore syringe or liquid culture to begin.
