@Papa_T, Yeah, short-term use of it will reduce risk associated with ozone and venting outside will reduce a need for a dehum for sure. If you are maintaining a safe range of RH% and it results in a VPD range you want along with temps, you don't need a dehum. Venting outside helps alot. If you get high RH in a cyclical manner in your region, you may need one occasionally. Before i grew in winter only, RH was a big problem in the summer for me and i vented outside back then. It became an invisible problem when i scaled up and moved to winter-only. I have a temp probe that can inform me of temp/rh/dewpoint without opening tent, nowadays... zero surprises. I used to be pretty festidious about cleaning.. then i had my multi-grow WPM issue that took a bit to recognize the cause. I got a bit pissy about it, lol, and didn't bother cleaning much. Around the same time i scaled down and all of a sudden the WPM issue abated. Which was a bit upsetting considering the time and effort i put into cleaning prior hoping it would help. This is the main reason i say climate is the biggest factor by far. I definitely had some spores "somewhere" that cycle but they never got a foothold. I've since cleaned of course. Haven't seen any WPM since then... next cycle will be 2 years. Scaling down dropped me to 27-28C during day, but the dehum could keep up properly and still 68-70F after lights out. Half the wattage helped with the temps. Half the canopy helped with the RH. WPM magically went away and before that particular run i didn't do shit becuase to clean i was so pissed. Before i was as high as 30-32C with 60% rh, which is a dewpoint just over 71F. Higher range of heat with appropriate RH has a dangerously high dewpoint. If it is a concern, download a dewpoint reference table or get one of those 10 USD temp/rh probes. Definitely useful with photoperiods in flower, anyway. It is important to clean, but you don't have to be crazy anal about it in my experience. A good wipe down with some sort of cleaning solvent is probably good enough for 99% of cases.
