i dont even monitor the humidity in my veg tent. sometimes theres water running down the inside walls when i open it up. 60 percent is fine in veg, dont want it to be more than that for any extended period of time really. i came back from a trip one time to find that i had my veg tent dialed too high so the fans werent running as much as they usually do and it was probably 90 % in there had some dead leaves showing some mold thats about all. no big.
