I am growing WW in garage. I am hiding it from my dad. I have the set up all correct and i germinated and the plants look great. I am ready to start using the HPS lamp. I've been using fluorescent bulb. As soon as the HPS bulb came on the temperature in my 5 ft x 3 ft x 3 ft went upto 100 F. I have an exhaust set up. It's a basic bathroom exhaust fan, take away air at 50 CFM. I think the problem is that the aluminum tubing that is coming from the exhaust fan goes out the box (at the top) and i bring it back down (to the floor) and drilled a hole in the corner of the basement wall and expelled the air out that. I am guessing that since warm air rises, it might be the reason why it's not taking out the hot air. I have a 400 watt hps set up. What can i do? there is no way i can have the duct going up. If i buy a inline duct fan, will that exhaust out the hot air? help
