eBay: SWITCHABLE 1,000 watt HPS MH GROW LIGHT 1000 1000w HOOD (item 180060104067 end time Feb-03-07 06:46:34 PST)

Can someone explain why this reflector has (2) 6" flanges on it? I thought you only needed one to exhaust the hot air form the light. How do you go about setting this system up? Where exactly you do install the inline fan if there are 2 cooling flanges? It says perfect for the CO2 grower, but with 2 flanges, I can only see the one sucking the room air in and the other flange blowing that air out of the room. But doesnt' that suck all the precious CO2 out? I'm all fucked up on this.................

one brings air in, one out, if you are using a co2 system, you run your fans on an opposite timer to turn off for a certain period of time while your co2 is running over the plants, at least this is how i have seen it done. you could always leave the one end open... but then you are just blowing the heat into your grow room..

what would you do if you had two lights instead of one and you only wanted to run one venting line? Lets see in one side of the first light out the other side to the second light. Does the light have a glass cover so it is pretty much an enclosed light? Then , what was I going to say..oh yea , engage your brain, at least look at some pictures, maybe widows grow room set up will help.

Now that makes sense victor 'the brain engager'. Having another light and tying them both in to eachother. If I were to invest in a light with cooling options, I would want to cool it continually and not partially due to co2. Thanks guys......

It's not so you can use two lights with it! Although you could do that, it's so you can use a charcoal filter with it, either inside or outside the growspace.

If you were using it with co2, you'd have to have them both on timers.

That reflector works really well. FYI: if you buy it off their website (High Tech Garden Supply) you'll save like $30 bucks on shipping.

Assuming you're growing in a closed system, like in a grow tent, you can set up the reflector so that it pulls air from outside the tent, through the reflector and back out of the tent, leaving the air (and co2) in the tent 'untouched'.

yeah, but splifman, with the reflector being fully inclosed having the glass, you're not sucking in any co2. So why would you want to bring in fresh air when all you're doing is blowing it back out anyways. I just think one single flange is all you need to suck the hot air out. Also, where would you install the inline fan for a sytem like this?

I don't think it's meant to bring in fresh air to the room. It's just meant to control the heat from the light. I'm not experienced with co2 use, but I think the point is to keep as much co2 in the room as possible. I'm assuming that the benefit of this set up is so that you don't pull co2 out of the room while trying to control the heat of the light by pulling air through the reflector. If you only had one duct attached to the reflector the air being pulled through the refloctor would come from the grow room, which could cause considerable loss of the co2.
I remember reading about this reflector and I think the reason it's 'ideal' for people using co2 enhancers is that the coolable reflector system is a closed system and doesn't pull co2 enriched air out of the room.

As far as the placement of the inline fan, it can go anywhere as long as it is attached to the duct so that it pulls air through the reflector. The way I will set mine up is have the duct that is attached to the reflector run out of the grow room through a hole in the side wall of the grow room. I will attach the duct to the fan that will constantly be sucking air through the duct. I don't use co2 so I won't necessarly need a duct attached to the other flange.
