Thanks for the info I will look into adding another light or two as I can afford it, as for venting I'm in Oregon so I will open the lower vent ducts and put a short piece of pvc pipe with a screen on it into them so the fan sucking air out of the top of the tent draws in cold air from the opposite side bottom vents. One thing I do need help with though is where to buy bulbs for the T5's. I am gonna need to swap out the veg bulbs for the flower bulbs but can't find anywhere to buy just the bulbs.
