you need them 2700 bulbs for budding, you need 5000-6000 for veging stage, ( where you are) its good to have one of the others in there too, to add balance, keeping ONE 2700 will make the plant have more offshots and not just straight up. If cost is against ya? just buy one 42watt 5k one.. here is tutorial on cfl, real basic but has the facts straight! https://www.rollitup.org/cfl-growing/107992-tutorial-growing-cfls.html
