181: Why Mastering Vapor Pressure Control Holds the Key to Exceptional Crop Quality with David Sandelman

Ever wonder why your plants aren’t thriving—or why your post-harvest yields and terpene profiles just don’t stack up? I’ve been there, and this episode is your shortcut out of the guesswork.

This week, I’m joined by David Sandelman, CTO of Cannatrol, inventor, and expert in environmental controls with decades of pioneering innovation under his belt. From the origins of digital thermostats to revolutionizing post-harvest processing in cheese, charcuterie, and cannabis, David Sandelman brings deep scientific insight and a passion for precision.

We dive into the real science behind environmental control—why traditional approaches to humidity just don’t cut it, and how understanding vapor pressure is the key to stable, high-quality crops across cheese, cannabis, and even hops. David Sandelman explains, in plain terms, how “water activity” trumps “percent moisture” for true shelf stability and consistent results.

You’ll also hear about the future of indoor farming, from AI-optimized grow rooms to what legacy cultivators can learn from the world of cheese and charcuterie. Plus, we dig into practical applications—whether you’re a large-scale producer or a passionate home grower—along with candid insights from David Sandelman’s journey in the industry.
