you'd do better buying an 1/8....

but,

4 bulbs, clipped to each "bar"
get an emergency blanket at walmart and wrap the cart using duct tape to affix. use where the ends meet as the entry.
using 1' chickenwire cut to internal size and affix each corner 14" up with wire to the "bars" make sure you bend in the edges so they dont rip the safety blanket
find 4" square pots enough to fill the entire area (about 20 if you will clone).
when your seeds sprout keep them on and 18/6 light schedule.
at 5 internodes, bend them over gently and hold them in the position with a bent piece of coathanger (make it like a hook)
after 3 more weeks you will guide the growth under the screen directing the chutes into the holes in the wire. (Or you could clone at this point and fill the entire space)
12/12 when the screen is full

you won't yield much in that space however if the intention is right, it's rewarding.

have fun, hope my 5 minutes helped a little.
