Some cultivars actually prefer RH above 65 for the entire grow. We only lower RH during flower to prevent mould and pest issues.That VPD garbage is a main reason for the flood of lower quality cannabis. 80 degrees and 70% humidity in flower will not yield high quality cannabis.
VPD is great for commercial greenhouses with Ag crops, etc
If you are growing in a room indoors the best temp/RH to strive for is Veg 77-80/50% Flower 72-75/35-40%
Cuttings or germination 88/high humidity
