Humidity Help Please!

[duckman]

hey ya'll...just starting my first real grow (yay!) but I'm getting worried about the low level of humidity in my tent. it is up and down a bit, of course, depending on the ambient conditions in my room but it has been ranging from 32 to 39 percent which I'm pretty sure is too low for a successful grow. the only time it goes higher (e.g. 55 percent) is when I turn the exhaust fan off completely (causing the temp to spike), obviously not a long term solution!
tent: 2 x 2 x 5 secret jardin
light: LED vivarspectra v300
substrate: happy frog and perlite 75/25
pots: 2 x 5 gal. fabric pots
Any suggestions would be much appreciated, thanks!

I have the same problem. I just leave my exhaust fan on.

When your canopy develops they'll be transpiring a lot of H2O. You'll be battling too much humidity soon enuff. If you're worried about your sprouts being too dry you can put a dome over them. A dry-cleaning bag and some bamboo stakes works great, and it doesn't require a trip to the garden center.

During the winter it's pretty dry here. My flower tent is usually 35% and they've done just fine. Veg tent I usually use a 5 gallon bucket, an aquarium heater at max heat and an air stone. That seems to be the trick for getting humidity in my 4x4 up about 5-10%.

I add a “cool mister” in my tent during early veg as I also struggle with low humidity. It works great and even helps cool down the environment. You’ll only need the mister for 4-5 weeks as you soon enough be fighting too much humidity! Lol, the ups and downs of our grow space!
