k.

as for the lights obviousely you would have the plants on 12 light at the optimum time of the day.

as for the window, there are windows you can purchase that are no see-able through but allow light through. That doesn't seem very practical though, mabe having the plants and lights a few feet back form a top story wouldnt be visible/noticeable?

temps would be hard you're right.

i mean like 2k w of light in small place though.

i thoguht this idea was neat while i was stoned but now it sucks, haha.
