Humidity and temp pref

**MrC** · 25-09-19, 01:15 PM

Just wondered what peoples day/night humidity and temperature sweet spots are. Googled it a lot but every site has a more varied number. So would like to know first hand from growers what you look for, had tent set up a wk(75x75x130 cm) with some practice seeds while I waited for the autos and as of now my night temp/hum is 22.8c and 52% humidity. Daytime it usually drops to around 27c and 44-50% hum.
I can raise humidity quite effectively with wet towels I've found, always seem to stay in the rough guidelines of 20-30c and 40%-60% humidity day or night. I understand this will be a changing enviroment and I have no extraction fan messing with it atm, will be in for the wknd when the seeds go in.

Thanks man, thought I was supposed to keep it lower than 70 but I'll bump it up. So 70% humidity is sound until flower 24/7 in your opinion? Do you grow in big or small rooms?

It's fine for flower as well, as long as you keep the air moving around. JMO

Thanks for the input, definitely be some trial and error, Rome didn't get stoned in a day

I shoot for higher humidity at the young seedling stage, around 70% ..as they progress over the weeks I don't mind that gradually falling to around 55-65%, then in flower to be below 40-50%
