Small or large i call everyone's grow area a setup. In my opinion you should add some dirt to the pots and get better lighting. You need something in the 2700 range. a group of (6) 23 watt per plant could probably be enough, The plants will double in size minimum during flowering and also require 12 hours of complete darkness. luckily they sell 23 watt 2700k at walmart, home depot, amazon, hardware stores, ect. I even saw a 6 pack in walgreens, a drugstore/pharmacy.
there are hundreds of ways of lighting a grow, just gotta pick one that has low heat right for your space.
