G'morning, I was having my wake n bake today and I stumbled upon a pretty neat artical regarding VPD in the grow space. More specifically, how temp. and RH in the grow space effect it. What I found to be really cool is the tables (cleverly labeled tables 1 and 2) showing what the RH in the grow space should be for a given air temp for both veg and flower. I thought it to be handy, maybe you will too
