The Dime Dr. Greenhouse: The #1 Mistake Killing Your Plants ft. Nadia Sabeh
What if keeping the room a little too dry is killing your plants?
Humidity—and the HVAC that controls it—drives plant health, but air isn’t uniform across the room. The fix isn’t more AC; it’s dialing VPD so humidity, lights, airflow, and irrigation work together. Get it wrong and you lose yield and fail tests; get it right and buds stay sticky, healthy, and consistent.
This week we sit down with Dr. Greenhouse (aka Nadia Sabeh) to discuss:
- Dry ≠ safe: why extra-dry rooms can actually spread powdery mildew
- Measure where it matters: a simple toolkit and method at the canopy
- Design for airflow: room shapes and layouts that keep climate even
