Introducing HID brought my humidity down 30%?

  1. Hi all - I am a new grower and I've almost finished my grow tent setup. I live in a low humidity region - Colorado. I was having issues with high heat and low humidity. I had 2 LED lights (135w UFO and 300W )and was reaching temps of 90-95, due to the room my 3 x 3 x 73 grow tent was located. I bought a portable Evap cooler and ducted directly into a 6" intake on the top of my tent. after doing so, I brought my temps to 73-77 and humidity to 60-70%. I've since added a 400w MH Cooltube and ducted from 6" intake on top, with a 240 CFM inline fan blowing outside air through to a 4" exhaust on the other side of the upper tent. I moved my Evap duct to the bottom of the tent and it's coming in a 6" intake. Since then, the temps have gone up to 86, but 80 at soil level, 83 at canopy level. BUT the Humidity won't get past 40% now. Any ideas? Does a MH depleat humidity in the air? Thanks!!

  2. The heat is causing water to evaporate and your fan is venting it out of the grow room.

    It'll be fine. 40% isn't that bad.

    I grow in 20-30% all the time, and get good harvests, but I'm in the desert and really have no choice...
  3. Is carefully home grown that much better then your tipically grown weed

    this is my signature. Right here.
