How much can you spend? No don't make your own soil in my opinion untill you get an idea of how soil works. Why the Big Bud strain, it works the way it is supposed to under HID lighting so you may want to choos a strain that is being used by other folks using CFL's with good results. Lastly, read, read, read, oh did I say read?
Hope the best, but get that budget question answered an you may be able to get some answers that you can use.
