So i bit the bullet and spent about 500 ish dollars on some sweet growing supplies. For starters i got this 400 watt light Lumatek 400W Complete Light Package w/ Xtrasun Hood & Lumatek Lamp + Free Timer & Light Hangers! and also got a CAN fan rated at 440 cfms and ducting to go along with it. Now my question is this i was going to originally hook the ducting up to the fan to the light to suck all the heat away from the light sense the light is enclosed but i realize now that i will only have one fan so i would not be able to create negative pressure. So my question is this could i get by this grow with just putting an osicilating fan in there and creating intake holes. Or do i need a real fan to blow air around in there. The tempatures should not be affected because the room is cold and all the heat will be sucked out of the hood. Thoughts anyone Oh and if it helps my lights fan and ducting are going to be used in a stealth dresser.
