I’m sure you have seen these 3 letters thrown around a bunch and it is a bit confusing .I’ve been using the Pulse labs grow room monitor to track and it’s helping me to think about my environment In a very different way.
I still have the paramaters I want to keep my grow tent in but when it comes to making changes I am going to make my ultimate decision based on vpd.
For example : If the vpd is running high I may go easier on the feed because the plants going to drink faster. For the veg tent if vpd is too high i try to raise humidity.
Im going to revisit this topic in a few months but figured might aswell throw up what i have learned so far !
