Humidifier, light, fresh air


#1

A question from a fellow grower:

I bought some white widow seeds from u for my first grow…I have a 36 x20 x62 apollo horticulture grow tent, 400w hps apollo horticulture light being cooled with a 6" ventech fan…growing in FFHF soil…

now my questions are…

  1. my temp is at a constant 78-79 degrees but RH is low between 30-40%…was thinking of just putting a small humidifier in the tent…thoughts?

  2. I have my seedlings about 12" away from my light, but I feel they can get closer…I can put my hand right under the light without my hand getting hot or even warm…

  3. besides the two vents for my lamp, there is only one other vent in my tent…so which is more important fresh air in or an exhaust to pull air out?
