I'm using a EZ hydrokit bought on e-Bay for $150.00. The bulb is a 125W reb and blue spectrum bulb that turns inside of the housing to point the spectrum you want down towards the plant.

I used foil because it was what I had availible and so far after testing for about three days the room never exceeded 80 Degrees. Usually depending on day or night the rooms temp is averaged out to be 76 Degrees. The buld is great for small spaces that is why I went with this dual spectrum bulb.

I might utilitze the space with 2 additional plants. I figured I might run into problems with only having one plant. The likellyhood of having a female is very low if I only grow one plant. I figured if the plants growing in soil were female and the plant growing hyroponically was male I would get rid of it and transplant one of the females to hydro for the flowering process. The room is 4 X 2 X 6.
