my concept to help with heat, what is your take?

so i live in southern cali where its regular to be 103-110 degrees everyday during summer, now is the time that the battle against heat begins. being that i have my 1000w light and blower and fan set up right now, i cant afford to run an a/c or swamper or anything to these little guys, so i began to think if i could make vent this thing a different way somehow. so i had my ducting going from outside the tent, inside, through the hood, to the blower, and out of the tent and into the attic. the blower is pulling air from the hood. heres the setup


i then figured maybe i should try to pull the heat from inside the tent, open some bottom vents of the tent and see if i could get some sort of vacuum going, sucking air into the tent from the bottom and blowing it out at the top. so i pulled the ducting and set it up this way


anybody think this will help with heat problems? i sorta realized the heat that was passing through the hood, was just hanging around in the tent. im using a 4" 160cfm blower and my tent is 5x5 and probably 6 feet tall

yah thats gonna be tough dude. insulate all of your ducting and anything else you can. your room is prolly too small to water-cool, so thats not an option. if you implemented co2 you could prolly let it get a good 10F hotter in there without causing stress.

Are you forcing any cool air into the tent forcing the hot air out through a vent? The ambient temp being lower seems like it would help as well? I'm still learning myself but seems logical to me. Good luck, let us know what you end up doing.

seems like it didnt help heat at all but im sure that it helped with air circulation right? creating a vacuum effect if im correct!

You got the jist of it but it's the opposite of a vacuum, forcing air in the tent increases the pressure inside, forcing air out of any open vents. Yes, it helps with circulation of air and that is very important too but I was hoping it would help with the heat.
