temp and humidity question

[rolljoeroll]

I am on my first grow and I am growing inside a tent. During lights out my temperature is around 67 and humidity around 35%. When the lights come on it goes to 86 with a humidity in the teens or 20's, is this too low? I have them under a 600w light with a air cooled hood vented through a charcoal filter inside of the tent blowing outside of the tent.

yep, your temp's too high and humidity too low. What's your set-up?

edit.......tent size?.........container size & type?.........substrate?

4x4x7 currently in solocups but have 1 and 5 gallon soft pots for transfer. FFOF with about 30% perrlite currently.85 is too high with the lights on?

'With' that humidity yes. Is your light dim-able? If your still in solo's you don't really need 600w and lowering the temp a bit will increase relative humidity. When you get more soil into the tent, that will also raise the humdity
