First I would like to thank for a good forum, I've been reading it for a while but this is my first own post (in any CB-related forum).
About a year ago I got the brilliant idea of growing my own green. Unfortunately I didn't have a good space to use but a few months ago when I got my new apartment I thought I'd found the perfect spot for a stealthy grow.
During the last couple of weeks I have been doing research and benchmarking on different gear that I was gonna use. And I have been drilling, painting etc. just to make everything ready for my grow room. Just when i thought everything was finished and im awaiting my seeds in the mail, i decided to try to measure the humidity and temperature in the room.
Since I didn't have any good ventilation possibilities for the grow room, i'd decided to go with one 2700/6400K (one each) 200W LE light. The brand is Envirolites with built in ballast.
My grow room has the dimensions (height x width x depth):
80 x 65 x 40 (centimetres)
31.5" x 25.6" x 15.7" (inches)
So, I started my light and put the thermometer on the edge of the pots (as I thought there's where the plants will be).
The initial temperature was 73 degrees Fahrenheit (22.8 celsius), then it developed like this:
10 min: 81 degrees (27.2 celsius)
20 min: 85.6 degrees (29.8 celsius)
30 min: 91.22 degrees (32.9 celsius)
40 min: 94 degrees (34.7 celsius)
50 min: 96 degrees (35.8 celsius)
60 min: 98 degrees (36.5 celsius)
I continued measuring and after aprox 8 hours it seemed to stabilize on 109 degrees (43 celsius) (!!!!!!!!!!)
Here's a picture of my growing room:

I know its a small room (the light can be brought up higher), but i wanted a stealthy growing room. I measured I have aprox 40-50 cm for the plants. I'm planning to grow lowryders / trying some LST-strategy/cutting down/bending the plants.
So, to my question.
Obviously I have a huge temperature problem and I was looking for some advice on how to fix it. One issue is that the grow space is in a cabinet space that is located next to the ceiling in the room. There is no way to create an outflow at the top of the room (except if i drilled a hole in the front panel, which would not be very stealthy). The only way new air can enter the room is from underneath, where there is another cabinet space. The openings to the room underneath is two x 1/4 inch "stripes" that located along the width of the room (the 25.6 inch-length).
I measured the temp in the cabinet beneath and noticed that the temp had not increased there, so obviously no heat is transferred between the two cabinet spaces (logical i guess since warm air moves upwards). Is there a smart way that i could get an inflow from underneath (through the small slots), or, rather blow out the warm air downwards? Or is this problem unsolvable without an exhaust in the top of the growing space? Can I use ice?
I was thinking about getting an ordinary oscillating fan to circulate the air in the room, and maybe i could cool off the plants just underneath the lamp. But i don think it will be sufficient. I also decided to remove the plastic sheets on the wall (the walls underneath is white anyway) as I figured the stone and tree walls inside the space maybe had better thermal conductivity . I'm measuring right now to see if it makes any difference.
Do you have any advice for me on how to cool things down? Should I just forget growing in this space? Im feeling a little desolated now after all the work with the room, and now this... Any advice is appreciated.
