I don't know LEDS with drivers, not until yesterday, but i would think its hot in there. My new light arrived yesterday, a Mars Hydro TSL 2000 and mannn was that thing hot. It's back in the box ready for return. I have 6 X 3 foot closet, use half to grow with my Bluprle BestVA 3000. The light is even too hot for the whole closet. They say you can detach the drivers and put them outside, maybe that would help if you have heat issues. Like I said, I only know this new light, and its so hot I'm returning it, and I think its the diodes more than the drivers but I know nothing about your light except that its Spider Farmer.
Back in the day I had a 75watt HPS security lamp that I took the see-through plastic reflector off of, replaced with an aluminum spot lamp one, and rigged the wires up so it could be plugged in. With a timer and a computer fan also rigged up to be plugged in, It hung in a 1.5 foot X1.5 foot x 5 foot closet space and I got some nice top buds but I think in your set up you're going to have to grow with multiple tops and tie them down. I would guess if it isn't too hot you're going to get a mossy carpet of buds. My experience..
Best of luck..
