Lol... yea its a spare bathroom.

2000 sq ft? that cant be right, my space is around, 9 sq ft. like 3x3, and I have for the flowering cycle, 25,000 lumen

basically, in my space here is my light cycle 3x3, I also re-pot into larger pots during each phase
seeds/sprouts, 2-4,000 lumen
6-8 inches 8,000 lumen
16-36 inches 14,000 lumen
then flower, throw as much as you can. 14,000 L is enuph to flower some great buds in a 3x3

also the reflector I made is not tin foil, its thin metal, you can buy it in a roll in various sizes & thickness's at the hardware store; not sure what type of metal but it does not contract very much heat at all.

any light you give a plant it will be happy, if you want them taller raise you lights higher, you need some space in between the leaf's, those become bud sites.
