wassup well zandor says go cheap grow cheap so withthat said for a better commercial grow high intensity distacharge lamps (hids:MH, HPS)are ideal but for a more money consient grower flourous/cfls will work except at a much less advanced rate due to the drasticly lower lumens content of flouro lights but this could be compensated by using more bulbs and amping up the wattage like a certain knowm i know does what was the last cont 14 15 cfls per plant talk about overgrow!, also hids emit much more heat then flourous and call for a good ventilation system in tight spaces not to mention bring up the light bills over extended periods of time but yet an still cant beat hps for flowering and mh's for veging.. so my answer would be in an economy free grow setup use all of the above cfls for sprouts an clones mh for veg an hps for flower..holla..
