ok so I’m growing in a 3x3x6 tent with a hlg 550 dimmed down. so with the light dimmed I can keep the temp around 23-25C but humidity is around 70-90 with a lot of condensation on the walls. I got a 6" exhaust fan hooked up to help with smell and humidity and pull in freh air, but it also drops the temp down to 18C when running so I got it on a timer to turn on for 15 min every hour.
so I was thinking getting a new 4" exhaust fan would be the fix, letting it run 24/7 and at a lower speed. just want to make sure that I’m not pissing away more money then I have to. and that the 4" is capable of keeping the smell down and pulling fresh air in.
growing in an unfinished basement and the average temp is around 15C
