TrueLeaf Story



We trace our roots back to a company called Biotherm Engineering

Founded in 1980, Biotherm Engineering was the innovator of the “bench-top” or “tube-heat” systems. What we now refer to as “BioTherm heating”. We now offer familiar products like Starfin, Duofin, MegaTube, and HDX.

TrueLeaf concept hatched!

In the Spring of 1999, we held a strategy retreat and decided that we had grown beyond the “little heat tube” company that we were still closely identified with, even 10 years after beginning substantial diversification of our product line. We decided that we would be best able to serve the market in the new millenium with a new name and a new mission. We decided to call the company TrueLeaf Technologies, adopted from the term describing the first leaf of a new plant and have toiled to create “Precision Environment Systems” for horticulture since then.

The focus of our company has been on making all these diverse systems work together in an integrated way

In 2000 we entered the "Flood Floor" business and have designed and sold over 80% of all Flood Floors in the U.S.

Into the Future!

Now, as we proceed with a well rounded and complete set of products and experts on staff, we want to help you as a grower do the best job possible using your precious resources. Especially with water, fuel, and energy becoming more expensive and more important to manage. Through unique and innovative heating systems, flood floors and more, integrated computer control systems, and water management products engineered specifically for each application, we can improve the bottom line of any operation.

TrueLeaf is new life and abundance. It’s about a new awareness of how our industry has changed. It’s about making the most of your investment. It’s about helping you achieve what you dream with your facilities, new or through renovation.

All the best,

Jim Rearden and Mike Muchow
