Would this be over kill in a 10 square foot space? I'd like to be able to have the tent closed up and the temperature be around 75-80 degrees. Right now I have to little seedlings and it's about 84 with 85% humidity, I believe those are decent conditions. http://store.portableairshop.com/ed90btupoair.html I want to run a 400w mh for a few days, I figure i'll induce flowering at about 6-12 inches on these, not sure what they are, I believe one is a bubba haze and the other is a med house seed from an unknown strain. I really need to keep the temperature down. If the temperature in the house is 75 and I run 400w and vent with a 145cfm fan will i be within an acceptable temperature range?
