Just been reading your issues in more depth about rh, as temps go up humidit drops and as the temps go down the humidity goes up. The way i combated this was to get a cheap shower fan ( dont care what ppl say. had mine for a year and it hasnt burned out lol ) when the lights were off i used to run that as an extraction, notjing to heavy but just enough to keep the air moving around, ive also learned that ive been over looking lights out and whats needed then. my tents in my room so at night i dont wanna be woken up by 6inch fans blasting. so this little 4 inch does the job. temp is also very important at night. if your hitting around 23-27 you only want that to drop by a few degrees at lights off. if it drops below 60 your run into trouble. i just turn the heating on for a our at lights off to get the abiant temp of my bed room around 23-24 and lights on im hitting around 27-28
Sorry pal i seem to have had a stoned rant on your post lol my bad
