In 1980, we were just teenagers with a bold idea: BioTherm Microclimate Heating. What started as a heating-focused company has evolved alongside the industry’s ever-changing needs. Today, we provide a comprehensive suite of climate solutions to help growers cultivate healthy, thriving plants—whether in greenhouses, indoor farms, or CEA facilities.
Our mission remains the same: creating the perfect growing environment for every crop, in any condition. Now, as we step into 2025, we reflect on more than 40 years of innovation and partnership. The horticulture industry has expanded, with new crops, technologies, and fresh talent shaping the future. BioTherm has been there every step of the way, ensuring our solutions evolve to meet the demands of modern growers.
Greenhouse growing is the future—and our technology keeps you at the forefront of innovation.
At BioTherm, we do more than develop products—we build partnerships. We collaborate with leading greenhouse manufacturers and distributors across North America to deliver seamlessly integrated climate solutions. Our commitment goes beyond providing best-in-class technology—we are here to support your success.
From our industry-leading Heating Systems to our Hydro Sciences division—offering advanced water temperature control and Dissolved Oxygen infusion—we help growers achieve optimal plant health and efficiency. Our Optimized Air division takes it further, with cutting-edge dehumidification, cooling, and CO₂ enrichment systems that work together to maximize yield and performance.
Whether you need a single system or a complete climate solution, BioTherm has the expertise and tools to support your growing operation.
Proudly based in California, we serve growers throughout North America and beyond. More than just a supplier, we are your trusted partner, ready to provide innovative solutions and dedicated support for your growing success.

During the initial consultation, an experienced BioTherm engineer will collect a Proposal Questionnaire from you to access your wants and needs. Our team will work with you every step of the way. From new construction to retrofitting old construction, we can design our systems to fit exactly where you need it to.
Once we know what you want out of your BioTherm system,
our team will prepare a project proposal for your review. We
do not start any project until our customers are fully
satisfied with our proposal and everything can be agreed
upon. We will outline schedule, materials, partners, and
estimates in our proposal, so you know up-front what your
project will look like and cost.
