Need answers to lots of questions.

eek that plant needs a make over =\ ok no halogen, remember thant!.. Flourescent lights , either tubes or compact will work but aren't the best, Metale Halide will work too, but the best overall is high pressure sodium, they're a red spectrum which is best for budding, as for the budding question, you have awhile to go since its so bare.. a couple of months at least

 

I can't tell to well from that picture but it seems, that the man grow tip was removed and the plant is pretty young, it'll take a minimum of a week or 2 to recover and begin to grow again, as lordkiller said, flourescents (tube or CFLs) will work well, and if u can afford the money space and heat go for the Metal Halide or High pressure sodium. For a plant that size and the shock, depending on lighting, fert, grow room setup, ur lookin at a minimum of 1-2 months of veging and 1-2 of flowering...so minimum 3 months (if everything goes right) but with the shock, ur probably looking at more like 4-5 months... GL keep us updated (read around a bit i know UNIOT has a tonne of amazing info in his signature so read it over and u'll be good to go).
