Spent a great time looking on the site today to try and find out about humidity levels, and couldnt seem to find my ansewr



Question i was wondering is whats the ideal humidity level to have during the vegetative growth, i ask because mine has been around 70 in my grow room and i was wondering if thats a problem? i relize that this would be real bad if i was flowering, but does it hurt now?

you want your humidity between 50-60% for veg growth and 40-50% during flowering, give or take 5%. this is for optimal conditions. you can vary probly 10% without much issue as long as it is low in flowering to inhibit mold growth.

70 is a little high, but humidity like everything else depends on strain. some plants are suited better for hot dry climates, others thrive in a colder/humid environment. it won't hurt them but it's best to keep it around 30-50%

so the 70% im seeing now is this real bad? i mean its just been real humid lately were i live and thats just what the humidity levels are outside, but do i need to get my dehumidifier sooner than i thought? also figure once winter comes around humidity shouldn't be a problem

i reccomend never misting your plants, even with plain water. it drains the nitrogen from the leaves and the water droplets act like tiny magnifying glasses and create "hot spots" under the light
