While in veg, you cn just stikck the cup under the canopy of your existing grow, you dont want that intense of light for the clones anyway. When in flowering, I kept the cup in the flower cab during night time(lights on in cab) and in the window during the daytime (lights out in the cab).
This worked well since I also have a very small grow space and it kept the cuttings alive for a long time with no real growth. When I was ready for them to start growing, I already had a bunch of roots in the water. I planted them in the soil, they looked like shit for a few days and then really took off. Worked for me since I did not want them to grow for a while, and I didn't have the second space for the time the clones sat in the cup and they still lived a pretty long time without growing much. I have had some basil in a mason jar in the kitchen window going for a few months.
