How to raise humidity?

Well here's my 2 cents, don't know the right and wrong of everything, this is just what I am dealing with.

During my entire run, my RH at it's highest was 40%, that was only after watering, and went steadily down, and probably averages around 25% or 30%, but somethimes, my meter just tells me to fuck off and won't even register.
I live in a very dry climate anyway, the RH is very low.
Hasn't caused any issues for me that I know of, and so far I am pretty happy with results, time will tell I guess.
My temps usually range from 80 peak, to 70 low, have had a few times get down to 65 and up as high as 85, not very often, it's almost always 80 or 78, everytime I look, with 25%-30% RH.
Works for me.:thumbsup:

RH always between 27 and 33% (Once in a while I suspend a wet towel in the closet with the fan on and humidity raise to 50% for about 10 hours... Like once a week)

temp always between 80 and 85 day and 65-75 night

1 and a half month veg from seed and they are great!!!

i realize this post is old but anyone happening upon this in the name of research should know:

humidity is relative. that is, a reading of 35% RH @ 75 degrees has less water in the air than a reading of 35% RH @ 85 degrees.

k my plants are now three weeks old and some of the leaves on them are staring to curl. the plants are still growing fine but the don't look %100 pecent health. i believe my problem is because the humidity levels are two low. but maybe im wrong.

high... hang a wet bath towel or two ! ... use hydroton system !
...as in, Ebb & FaFaFlowee !

i maintain 50-60 percent and it helps alot, the better the climate = better bud, faster growth, more yield, and of course a sooner harvest.

humidity helps fight off mites too, and also makes it harder for them to even begin spawning. can stress how important it is, the lower the humidity the more your plants are stressing to stay cool.

all plants have humidity requirements, if your temp is around 68-70 your humidity should be about 50-60

if your going for 75-80 degrees it should be around 70 percent( because of how hot it is your plants will need to transpire if that moisture is not in the air) in ordoer to avoid mold and such make sure the humidity drops properly during the night cycle. ive seen major changes from increasing humidity, make sure you get a good tool for measuring it.

i had a humiddity of 25% just boil some wather and let it cool down in your closet works fine

70%? That's a lot of humidity. I suppose in an ideal setting. If you achieve 30% - 45% you are doing fine. Later in flower drop it to 20% - 35% to avoid bud rot / mold issues. Also note that humidity in the 70% range will shorten the life of any carbon scrubber.
