Well, a cool-tube is a vented reflector; it just isn't the only kind. Its basically just a tube the bulb goes in. :wink:

Here's a picture of the basic idea, although I'm sure they must have them with better reflectors around the tube... :shrug:

There are other enclosed reflectors that you can hook ventilation up to. You'd need an extractor fan rated at least 126 cubic feet/minute for that room, to remove at least twice the volume of air in the room. A properly ventilated, enclosed reflector should help cut down the distance between the lamp and the canopy pretty well, and a fan blowing the air in the space between the canopy and light will help with that as well. 600 watts for that floor space would be excellent. I think the general idea is 2m² floor space for a 600 watt HID light, but as long as heat isn't an issue from the smaller floor space, I'd have to think that it would be more ideal to use it with that much space, since the plants in that smaller space will yield more. I really don't know, though, at which point there would be too much light, which would cause bleaching of the leaves and other problems. Like I said before, I couldn't think it would really be a problem, but I'm hoping someone who knows more about that would chime in, because I have almost the same floor space as you are expecting and will have a 600 watt HPS as well. :lol:

Since odor control would be such a concern for you, I think it would be worth it to invest in another extractor fan with an additional carbon filter. It is possible that a carbon filter, especially after a couple months and towards the end of the flowering period, might let some of the smell through. Having two carbon filters would help with this, especially if you alternated their refilling/replacement so that by the time one of them gets closer to the point where its reaching its capacity for particle absorption, the other one is still optimum. The added benefit, of course, is that controlling temperature would be easier with more ventilation. Insulated ducting could be a good idea as well if the sounds of the fans in the ventilation ducts would raise the concern of others in the building. Anyways, anything to help security in such a situation as the one you'll have is worth it, imo. :smile:
