It has been a few days since my last post. I've been pretty busy and still havent found the time to get some images up here.

I'm very excited as I just got a new 600hps for my growroom. I've taken down my WEAK flouros and put up the new HPS and I have to say what a HUGGGGE difference in the amount of light emitted - I never knew how bright a hps actually was.

My HPS is actually a HPS/MH running a 600 watt conversion bulb. I've looked into the light spectrum it gives and it will definitely do the job for me.

Now I have just ONE question about my light. It is a 600 watt, and my grow area is approx 1.5ftx5ft which will give me about 80 watts per square foot. My problem is that I have absolutely no way to keep a constant supply of fresh air to help cool the room. I do believe I will run into some heat issues as I read another post on here about a guy using a 1000 watt (not sure of his room dimensions) and he had 86 watts per square foot.

Any ideas on cooling the room off? Perhaps open the door to the grow room at night to let fresh air circulate? I don't want to open the grow room while the light is on simply because it is so damn bright.

Any and all suggestions are much appreciated!!!!
