VPD = vapor pressure differential.I have ALWAYs, kept humidity 60 and under(55-60) with plenty airflow to avoid budrot. I’m usually running perpetual rooms so there’s always buds finishing. You could def run a little higher early flower and drop it down later when buds are finishing though if you wanted.
I like my Klein temp gun that I got but i’m sure the one at Harbor Freight will work just fine
And BTW, i’ve been known to nerd out on a lot of things but nerding out on VPD is not one of them. Like I said though, i’m usually running bigger perpetual bloom rooms.
Had to look that up.
