MycoClimate Medium 44Q Monotub Automation Upgrade Kit

Already have a 44Q Medium Grower’s Select Monotub? The MycoClimate™ 44Q Automation Upgrade Kit gives you everything you need to convert the tub you already own into a fully automated, climate-controlled growing system—adding precision temperature control and consistent fresh air exchange without buying a whole new setup.

Designed for growers who want larger yields with less guesswork, this upgrade kit bundles the same automation, lighting, and filtration components found in our complete MycoClimate™ system—so you can dial in stable growing conditions using your existing 44-quart tub.

The kit combines water-bath heating, filtered air exchange, and integrated lighting into one streamlined upgrade—reducing the environmental fluctuations that can slow growth or impact results.

At the core of the system is a digital aquarium heater that gently warms a water reservoir beneath your grow chamber, producing consistent radiant heat that surrounds the substrate evenly—eliminating hot spots and helping retain optimal moisture levels.

The kit also adds an active fresh air exchange (FAE) system. A quiet electric air pump continuously pushes filtered oxygen through a HEPA-lined silicone hose, reducing stale air buildup while supporting strong mycelium growth and healthy fruiting conditions.

Paired with a full-spectrum LED grow light and a programmable timer, the MycoClimate™ upgrade turns a standard passive monotub into a hands-off automated grow chamber.

Add your preferred grain spawn, bulk substrate, and liquid culture or spore syringe to begin your grow.
