Grow mushrooms.
At home. On your terms.

MycoClimate is an automated, home-friendly mushroom cultivation chamber designed for creators, hobbyists, and anyone curious about growing their own fungi.

How it works

A complete climate system
in a single chamber.

MycoClimate replicates the natural growing conditions that gourmet and medicinal mushrooms thrive in. A microcontroller reads humidity, temperature and CO₂, then drives the humidifier, heater, fan and lights to hold your target conditions — species by species.

01

Humidity

Ultrasonic humidification keeps the chamber in the high-humidity zone fruiting bodies need to form and hold shape.

02

Temperature

Heater pads with closed-loop control let you dial in the temperature range for the species you're growing.

03

CO₂ exhaust

An exhaust cycle vents accumulated CO₂ so fruiting bodies grow with proper morphology, not stretched and spindly.

04

Light cycles

Programmable lighting drives circadian cues — important for pinning, color, and healthy development.

05

Sensors

Onboard sensors continuously read the internal environment so the system can react in real time.

06

Custom UI

A built-in interface lets you tune every parameter — no laptop, no app store, no cloud account required.

Custom UI

Tune every parameter — right on the chamber.

No laptop, no app store, no cloud account. Set humidity, temperature, CO₂ exhaust intervals and light cycles directly from the built-in interface.
