Well, I imagine you could call a local hardware store and ask the electrical, or anyone department. You can clone and keep a mother in the same area under MH or CFL's. I have mothers under a 175w MH and I also have 6 23w CFL lights in there that I can take out when not in use by just removing the bulbs for the MH to penatrate threw the cabinet, the rack of CFL bulbs are lined up under the MH light and when I have baby clones I just turn off the 175 MH and turn on a few CFL lights and this will keep the mother doing alright too, then when the clones are rooted and ready for more light I take out the CFL bulbs and flip the MH on. But all the same, you could just use CFL lights for clones/veg and mothers if you wanted to, I have done it that way.
If you go with a small area for mothers/clones with some CFL's you could put more money into your flower room lighting and maybe get a 600w ballast. Well, I will try to find some stores in the UK that you can order from, there are quite a few good ones.
