hey nice grow man. I am currently using only 4 26w cfl's. 2 are daylight bulbs and 2 are soft white bulbs. I have 12 8 inch flowers all in dixie cups bunched together under an aluminum foil wrapped box and there all doin just fine. No stretching and very bushy healthy flowers. I understand that 4 lights doesn't seem like alot but they are all getting lots of light cause of their close proximity to each other plus the confined light reflecting grow area. Of course I am going to be weeding out the males which will leave me with about 6 females hopefully and besides adding 2 more 150w equiv. soft white bulbs I don't think that I am using too little of a light source so I think your doing just fine with your setup. I think that more light is needed when the actual plants are further apart. the fact that my flowers are all within 5-6 inches of each other helps a lot. I am also using mg soil and there only 1.5 weeks into flowering and 4.5 weeks total age from seed. It's funny cause my flowers look better and healthier then other peoples who are using way more light then I am as well as better soil and bigger pots. :thumbsup:
