600 HPS Stealth Perpetual Secret Garden

I have started by stealth flowering room. It will be in an exisiting cabinet that is 3 feet deep by 3.5 feet wide by 5 feet high.

I have purcahsed a 600 Watt HPS as the sole light for the room. I have a temperature/humidty controller on the way.

I have 4 inch duct work to carry the air directly outside. I have on hand a 6" inline cheapo fan from Home Depot that I am hoping will be enough to ventilate it and keep temps under 85F. I am guessing I will probably have to set up to a 6" vortex however; I will soon know.

Tomorrow's goal is to set up the light and exhaust fan and let it be a couple of hours to see where the temps are at so i can decide my next step. Hopefully get the first picture on here.

Till then.
