Vertical Grows and Heat

with setup 3 you can have a plant growing in the center of the circle of lights...maximum exposure...

haha yeah that would be bad ass. Actually I think set up 3 would be the best way.. with all those bulbs in the center it would be like a real 3D sun haha.. and I could keep switchin out which plant gets to go in the center.. Hell yeah yo I'm picturing it in my head and likin it.

from the sounds of a 12x10x10 room its a bedroom with a window?.. ive seen people have wall or window mounted a/c units running which you can run on a timer and figure out good intervals or just keep it on cool, not super boost ice mode.

What do you do about smell when using AC? Any idea? I'd like to run vertical with AC come Summer time.

Portable units often vent hot air separate from the room, but if not you can always run a carbon filter through the exhaust.

I have my portable set up so that the exhaust hose runs to my bathroom. I run all my venting to my bathroom, and then just keep the bathroom fan running to vent out the heat, works well. The dual hose barely puts out any smell.

a honeywell fan blowing up under the light will control radiant heat from the bulb.
Then control ambient room heat with ventilation...

Another option would be cooltubes, although I wouldnt run them if you could help it.

I may be uniquely qualified to jump in here. I grew with 3600W stadiums for about 5 years with bare lights and have grown trees with the air cooled lights hanging down the middle for the last 3 years. Next week I'm changing a room over to the 4 plants surrounding a bulb set up. Actually two bulbs stacked.
The stadium was a 30% improvement over the flat garden. They were three shelves per side,12' long with 96 plants total in two gallon bags. I used Promix with Dutch Masters Gold and hand watered. Yields were excellent but it was a lot of work, not to mention the paranoia of having well over 100 plants in my house.
The tree set up is two banks of 3 lights with 10 plants around them. Same nutes,medium and hand watered. Interestingly, after dialing it in, the yield is about the same. But it's a lot less work and I sleep much better.
Next week I'm changing a room over to stacked lights because I think I can do better that way. It seems that lighting scheme will light the entire plant instead of the top 2.5 feet or so. The lights throw no light above the socket and very little more than a foot below the tip of the bulb. No light is cast downward, though with the ducting it would be blocked anyway.
I'll be adding two more lights to the new room so controlling heat may be an issue initially. My rooms are sealed and presently use a 17k btu window unit each for cooling. I'm probably going to larger units next summer as these barely keep up in July and August and are running constantly. When I bought them my electricity was limited to 110v and that's the biggest I could get. My new place I can run whatever voltage load I want so a lot of things will change next year.
Aircooling 3600W with an 8in Vortex is no problem. The radiant heat is a real pain in the ass. A fan blowing up from under the lights helps, but brings it's own set of problems like dehydration and windburn particularly with lights surrounded by plants.
The moral of the story is a small portable will not cool a 3600w room even a little. For efficiency's sake you don't want to exhaust conditioned air. So imho a sealed room is the only way to go. About 20k btu will keep it cool even in the middle of summer. Put the small fan on top of the filetr and put it over in the corner and let it scrub/recirculate. This way you can add CO2 and all your dreams will come true.
Happy trails,
