Lost With Humidity

Ok have a very small grow room and have purchased two humidifiers and still can't get my humidity higher than 30%, anyone know how I can bring my humidity up?

I wouldnt worry about it, I too live in socal with a constant 20% in my cab. I bought a decent sized humidifier and it only raised the RH by 3%! I said fuck it, and returned it to the store.

its just that time of year i to have had rh issues but i guess its wasnt a big deal as i will be pulling a harvest in 2 to3 weeks however as the plant gained mass my rh stabilized at around 35 to 40 which in turn is perfect for flower

throw more plants in there and your rh will rise

shallow buckets of water and a warm mist humidifier like vicks something cheap...

and secondly... your hygrometer reading is going to be off under direct light florescent or hid or whatever lighting being used... and it will always read a lower % plus the hotter the light fixture is the quicker it will turn the water in the air to evaporate into separate gasses and then that also makes the humidity go down as well so keep light cool and should help increase humidity as well
