Hello
I think I have recently come across a probably already know physical phenomenon? Atmospheric pressure differential. After my last grow under several +psi, I find that plant veg growth is quite reduced. This seems likely due to related to or reduced transpiration rate due to humidity; since differential pressures will factor heavily into this measurement. I ask if anyone using a negative pressure grow area (-2 psi or plus), has noticed proven greater veg growth under -psi? The idea being that an atmospheric vacuum favors a plants veg growth that is transpiration dependent?
