Hay all, I am pretty new to indoor growing. Only been doing it for a couple years now. Most of my experience is outdoor, of which I have many many years experience. Outdoor you really do not concern yourself with VPD as you can do nothing about it. My current indoor setup is in flower and running a VPD of 1.6. I know that the optimum for flower is a VPD of between 1.0 and 1.5. Should I be all that concerned about being slightly outside the optimal range?
