Anyone believe in VPD thru out a grow cycle?
Interesting you mention that RH Is not accurate for actual moisture. I wonder if that is why it seems that every guide and article says to keep the RH around or below 50%? Keeps things in a safe range I guess.Are you guys talking about actual mould or PM? I grow outdoors in the summer and humidity is 85-90% with temps in the high 80's. Some of the auto's I have ran are prone to PM but the photo's never have an issue until late in flowering when rot can happen. Being RH is not a true indicator of the actual moisture in the air but the amount at that particular temp I would think VPD would be a great tool. I actually keep my humidity low but it can creep up to 65 and have never had issues inside, it's a photo only zone as well lol.
What should happen then? Honestly everyone knows what VPD is and how it operates. Its basic gardening when enriching. Its like in the first sentence. Wouzer said it when he flipper over fillper truster. You know that.Also, Id be surprised if half the people commenting in here even know how VPD functions
