heat issue

like the title says i have a heat issue. im running a 400 watt mh in a 42"W x 32"D x 84"H. i have a 160cfm still air inline fan from lowe's hooked up to a sunspot6 air cooled reflector. i have a 6"fan blowing up from behind the table, and a small walmart hepa fan blowing over my plants. i moved the light up almost to the top of my closet, close to 3' away. i have to keep my closet door open about 12" to keep temps below 80. any suggestions on how to fix my issue? any help will be appreciated. i have $120 in my paypal account to try to fix the heat issue.

almost 70 views and not even a single "get a bigger inline fan". i know i need one but dont know what size. the inline fan is double what my cubic feet of my closet is. i just dont see how 160cfm threw a air cooled hood isnt keeping my closet cool. and my light is like 3 feet away from my plants. im used to using 4' floro's to grow with and bend my plants. i want a real grow this time and i need some help. because im a noob when it comes to using real grow system. it's free air flow going into my grow room around my exhaust hose.

AC AC AC AC !!! haha

i only have $120 to spend right now. it would have to be a small a/c im growing in my closet. any suggestions on where to get a small a/c?

You can try hooking up a intake blower , at the very bottom of room, and run flex hose from it , to the coolest part of house( or out window, ect.) Good luck !

yeah, just crack open a window or sumtin. i got CFL's so i dont have that problem

i live in NY so winter is here. so an open window wont real work right now. half of the window is at the foot of my bed. and i already have enough wrong with me. i dont need to get sick. i have a lowe's 160cfm 6" still air inline fan already. what size inline fan should i buy? like should i buy another 160cfm inlline fan or should i buy a bigger inline fan and use the bigger inline fan for exhaust and the 160 for my intake?

i live up north man, its winter as FUCK up in here and the windows at the foot of my bed to =O
so i cant open mine either you should switch bulb to CFL

ive used cfl's before but wanted to step it up a little and grow some good stuff. i ordered seeds from attitude. doing bagseeds right now to do all my testing on. i dont want to waste good seeds by all kinds of stress. plus i have my mimosa's in my closet also. should i run neg air or get another same size fan for intake?
