i have a dehumidifier and I use it in my flower tent but down the line I wonder if I might flower in both tents and if I did, if I would need another dehumidifier. I think I would but I’m wondering if anyone lets their humidity go up places where other people say it shouldn’t be like 65-70? With the thing on my flower tent is about 35-40 rh but I think without it, it would be like 55-70. Just want to know what the highest anyone has had the rh in flower without having mold or anything? I have heard the highest you should go is 55% rh.

Are you running C02 in your tent?

The question is more like what RH do you want to set your dial in at?

In reality...65% is the VPD prime and even Ed R say's 65 is optimal BUT, for the possibilities for PM....55 is about it... and he prefers 50%
