OK, here's what I would do. All you need for one clone is two 26watt cfls. That's what I use - 2 bulbs per plant is plenty. You can go to a hardware store and get a cord/socket ($4), two-pack of bulbs ($6), and a y-splitter for the socket ($2). The only other cost would be what you use to clone. I use a "float and grow" thing with peat plugs. Just a styrofoam slab with holes for peat plugs to sit in. The slab fits in a standard prop tray and floats on top. I think it was $12 at the hydro store. So for about $25 you could get it done. Oh, you'll want cloning gel which is another $10. Might be tough in the beginning because you will be short on space but in the future you might want to stagger the age of the plants. It will take a cutting 10-14 days to pop out roots. Then when you transplant it will take another week to spread the roots through the pot and start growing again. Then you want to veg it for another two weeks so you want to plan for moving a set of plants into flower (and also harvesting a set to make space) about once a month or so.
