Is high humidity at night bad for cannabis?
During day, I can maintain the grow room temperature to 75-77'F and humidity 55-65%. But at night, temperature raised up to 77-80'F and humidity up to 70-80% because I closed vents and air condition. Could this effect my plants in long term? Should I open vents at night also?

Extraction can size for 2x2x5 tent ?
Hi guys I'm about to set up my first box, I'm missing just the extraction. Box is 2x2x5 and I've got led light 120w. No smell is the most important for me. Is 4" fan with carbon filter going to absorb all the smell? Many thanks !

RH too low in indoor grow. Solutions?
I'm having a issue with my grow - RH won't go above 20%. With a humidifier inside, full power. Temperatures are between 21 and 25c and I can only think the air extractor is taking too much air out of the grow, as in the night, with lights and fan off RH rise to +80%. Any ideas?

Autos week 3 veg but only 4 nodes – could humidity swings be the cause?
In a 60×60 cm grow box I’m using a single-membrane mist maker with an STC-3028 humidity controller. Even with the exhaust fan at the lowest speed, RH swings every 2–3 min (67%→63% in ~90s, then back in ~90s). Is this fluctuation OK? My plant has only 4 nodes in week 3 of veg.

High humidity during flowering
I don't have an exhaust fan since this is my first growth and I'm quite on a budget my humidity averages around 65-75% I know high humidity increases risk of mould and bud rot is it necessary to get an exhaust fan and aiming for 40-50% or just risking the consequences?

How to Lower Humidity
The weather outside was really wet and chilly for days here and the humidity is about 60% at this point. Without a duct fan, how can I lower the humidity in the tent? I'm using several small fans right now. I plan to get a duct fan when I can, but I need something until then

Can't vent exhaust fan outside, is this a problem?
I have my 2x2x4 tent in a closet, with a 4" carbon filter inside the tent and a 4" inline fan outside of the tent, exhausting. But I have no way of directing the air to outside or even out of the room. Will this be a major problem for me? Room is otherwise AC'd via central air.

What light to plant distance would you set it at? The only test I've done is at 25 inches its stable at 80°f and 75% humidity. When I lower it to 18 inches, the tent read 85°f and 73 humidity. Other question I have is what's your favorite air stone(disk)? Lastly, add c02 yes/no
