1, your gonna need to keep reading up on the facts and basics. 2. eventually that 60watts, will need to be replaced - if you plan on continuning this already started effort. (Lowes carries plant lights, so do many other retail stores) You'll pretty much need to transplant those new plants, into something a bit more reasonable, like a 10 or 12" pot. I'd say your total cost for an upgrade be's about: $20 bucks, just say the light is most of the price, excluding the pots which might be about a buck 50. Looks good so far.
