daisydobey,
To answer your question I am growing 4 different strains. White Widow, Carnivil, mostly sativa, and Big Bud, and Kandahar, mostly indica. I germinated 2 plants per strain, total of 8 plants.
CFLs I am using are the larger ones, take a look at my album. Order them from Express Bulbs
I am currently burning 10 CFLs during the flower stage. My plants were about 14-16 inches tall when I went to 12/12 light schedule. The plants had completed their 9th week from seed by then, so I went to the flowering stage. However when you go to flowering stage, your plants may double or even triple in size. I have a small grow room, 3 feet by 4 feet by 9 feet, roughly 12 square ft. So I have all the light I can handle. Also each light has a clamp on fixture, so I can place my CFLs anywhere in my closet, i.e. lights around the plant as well as above. Take care, hoped I helped and good luck. BTW different strains means different ripening times,
