Humidity issue

I have a potential issue in my Secret Jardin. Tent's 5 x 5 in the cold basement with LEDs. I added a heater that keeps it between 72-80* . RH is hard too keep up tho. I have a Vicks small room humidifier blasting continuously, and can only get up to 40%. It's usually around 30-35%. I've tried to re-position humidifier and fans several ways with no improvement. Am I just being too OCD, or is there a better way? Thanks in advance!

Have you tried adding bowls of water inside the tent as well? Not a wonderful solution/addition, but it should help even if a little bit.

Do you live in an environment of typical low humidity or is it just the basement in particular?

Yeah it's getting pretty cold here in the Midwest. I have put a bowl and wet towel to boost it around 40. Too annoying and takes up space! I'm trying some leaf mulch now to keep plants above something moist. Been one day, and the leafs are maybe half dry already. Maybe a diff mulch or certain heater, humidifier, and fan combo I'm missing?

I think you're just fine at 30-40% RH. Especially when flowering comes around. I grow in 20-30% RH and it's a little rough on the plants when in veg but doesn't seem to hurt in flowering. I just need to water more often.

With a name like moldy, no wonder you don't mind low humidity...JK :P Yeah, I wouldn't mind if they were in bloom right now. This is my first time vegging this time of year, and I'm not used to anything under 50-60.

Well I just sealed tent and left front zipper about 1/4 open, turned fans on low, no exhaust, and it's now 45% after 30 min. I like the to get ROUND 55-65 RH for veg.

Ummm...how so high?! I'll trade ya.
Im thinking its the fact that I have been venting directly back into the garage due to the fact I live up north and im going to be dealing with -40c/-40f outside the areas. I do run a propane heater when I visit the area, which is twice a day, but with out a natural gas furnace its too hard to control. Thinking once I get my two areas going ill be running the 12/12s at opposite times, this way I can have my 600w or my 400w running at the same time as my space heater (15amp breaker). I also suck the air from one space into the next, this should help with the heating issue. lucky so far its only hit -20c for a couple days (my garage dipped to 5C and grow closet dipped to a 14C) then went back to -5c. But come January ill be having some new issues im sure lol.

After a day or so, I've been mostly sealing my tent with no exchange...just heater, humidifier, and fan circulating. Open tent at night. Young veglings look much better at 55-60% than 30-40%. Sometimes people overlook the fundamentals of a proper environment. Hope this helps some of you growing in the cold.

Living in a desert with a name like moldy is a contradiction. I've never seen mold (in my buds) but got my name working in a plastic "molding" company about 20 years ago. The boss called me moldy since I was training QA techs how to use the molding equipment at a plant start up. The plant closed about 10 years ago and I was able to transfer to a home office.
