My Card Board Grow Box

[element2k10]

I have a Cardboard box that is a dual wall box. its size is 24x24x36 and it is covered with plexiglass and has 2 exaust fans pulling air ouut and 1 hole for intake then i have a 400w hps in a cool tube which exausts the heat from the bulb directly outside the box is lined with mylar and the temps are about 90 or a little more ill just add another fan to cool it down a bit. what do u guys think the box is in the attic where it is dry and it wont catch fire because of the cool tube. what u guys think should i make any improvements?

sounds fucking ghetto dude... +REP... for 400w hps in a cardboard box..!!! temps are way to high 80*F is alright

well ima run another fan blowing in and another one out so temps will stabalize and the lamp is already cooled so no source of heat and an oscillating fan in the attic will cool it even more so the temps will be w.e i want them to be
