Every equipment vendor in the cannabis space wants you to believe that crop steering requires their hardware. Drop $10K on their sensor platform, subscribe to their dashboard, and suddenly you’re “steering” your crop. Miss a payment and you’re flying blind again. That’s a sales pitch, not agronomy. Crop steering is a set of principles. It…

You had a bad run. Yields came in light. Trichome coverage looked thin. THC tested lower than expected for that cultivar. You blamed the environment, maybe the nutrients, maybe just bad luck with the pheno. But what if it wasn’t any of those things? Hop latent viroid (HLVd) doesn’t kill your plants. It doesn’t cause…

You check your controller. It reads 78°F. Everything looks fine. But that 78°F is a snapshot. Over the last 24 hours, your room told a different story. Your AC cycled on and off hundreds of times. Each cycle pushed the room through a 4-8°F swing. Your lights cut at midnight and the temperature crashed 10°F…

If you’re managing a commercial grow room by relative humidity alone, you’re flying with half the instrument panel dark. Relative humidity tells you about the air. VPD tells you about the plant. VPD combines temperature and humidity into a measure of evaporative demand. For a quick starting point, established veg often sits around 0.8–1.2 kPa…

Your genetics don’t change between runs. Your nutrients don’t change between runs. Your lights don’t change between runs. But your yields do. The variable almost every time? Environment. Climate control isn’t a checkbox on a facility build-out list. It’s the single biggest factor separating a 2.5 lb/light average from a 3.5 lb/light average. And the…

Every cannabis operation obsesses over flower. Genetics, environment, nutrients, training, light intensity. All of it matters. But here’s what the data consistently shows: the two weeks after harvest are where 10 to 20% of your crop’s value can quietly disappear. Overdried flower. Sloppy trim. Inconsistent cure. These aren’t dramatic blowups. They’re slow leaks that show…

Commercial cannabis drying room parameters, airflow, water activity targets, and SOPs for commercial growers. Practical guidance for the real world, not the ideal build.

Ask any commercial cannabis grower what they pulled on their last run and you’ll get a dry weight number. Maybe a grams-per-light figure if they’re feeling precise. But ask them what their trim ratio was and you’ll usually get a blank stare. Or a shrug. That’s a problem, because trim ratio is one of the…

Every cannabis grower has a target number pinned up somewhere. 78°F. 55% RH. 1.2 VPD. Maybe you’ve got it taped to the wall next to a feed chart or burned into your brain from a forum post you read three years ago. And that number isn’t wrong. But it’s also not the thing that’s holding…

If you run a commercial cannabis grow, you’ve asked this question. Probably typed it into Google at 2 AM after a disappointing harvest. “What’s a good lb per light?” And you got the same answer everyone gets: 2 to 3 pounds per light is average, 3+ is great, anything under 1.5 means something is wrong.…
