Plants absorb light thru the tops of the leaves and breath thru the bottom. So it would probably be best to hang those lights. Ok next thing.....get rig of the tin foil!!! It reflects heat not light and it will burn your plant. What type of light bulbs are in that lamp? I cant tell from the glare but i hope they arent regular bulbs.
Regular bulbs dont do anything for your plant but give them heat. The other bulbs you have are good, you might want to get some more. The more light you have the tighter and bushier you plant will be.
