I'm there now with temps outside -15c - -20 c overnight. I can't keep my indoor humidity high enough. with out humidifier in flower room I was down to 17% I added a small 1 gallon humidifier and it only brought it up to 22% added another 1 gallon humid. I've got it up to 35%. My veg room with humid. is only 35% I'm having some leaf issues but they're surviving not thriving with slow growth.Hi, I am looking to start growing and I have purchased tents cmh lights day/night fan controller etc. I am wondering what you guys do in winter if you live in a cold climate where the humidity inside is supposed to be below 40%. During winter it is almost always colder than 20F usually stays around 0F or -10F according to this website and a couple others https://www.hvac.com/faq/recommended-humidity-level-home/ the humidity in your home during those temps is supposed to be no higher than 25% for -10F and 30% for 0f. I was wondering what suggestions you guys have? Is it okay to grow at those humidity levels because I have been reading about 40-60%. I don't know if it makes any difference but I have autoflowers.

hole in roof is in tent roof.i live where it’s winter now and growing, get a good humidifier!
you don’t have to have the carbon filter hooked up, exhaust fan was though, sucking out a hole in roof, not as much suction as filter in tent.
till pretty much flowering and i did have humidity anywhere from 50 -65+ depending on what i was doing, i’m flowering now with humidifier still going and just hooked up carbon filter, humidity has dropped to around 40, so i spray the inside of the tent a couple times while lights are on for the first week or two of flowering, than all should be fine, 40 is good for buds.
That's probably what I need, I've been relying on cheap 1 gallon Humidifier /misters thinking this cold snap will disappear soon. We normally have a high humidity issue and I have a good dehumidifier for that but this low H stuff is stressing out my plants.I use a whole house humidifier so the plants and people live in above 45% humidity.
Dehumidifiers and a/c keep it below 60% in summer.
this humidifier:
AIRCARE 6-Gal. Evaporative Humidifier for 2700 sq. ft. 831000 - The Home Depot
With a large reservoir and extended run time, this humidifier is a customer favorite. Casters make the humidifier easy to move once filled. It has three fan speeds, an adjustable humidistat, refill indicator,www.homedepot.com
