Most growers treat the dark cycle like a danger zone, cranking dehumidifiers until the room is bone dry out of pure fear of Powdery Mildew. But you're missing the biology lesson: plants do their heavy lifting—cell expansion and stretching—in the dark. This requires maximum turgor pressure. If you dry out the air while the lights are off, you're starving the plant of hydraulic power right when it needs to build its frame. In veg and early flower, let the Night RH rise. Rely on your airflow to kill the mold risk, not the dehumidifier.
