se the plant in my avtor, that was vegged for 5wks with 4 x 18w cfl n flowerd with 400w hps and they were fucking massive, im talking 7ft, i had to lst the bastards. hudge buds 2. it can b done fella.
u can totaly veg them with that amount of light m8, just keep the bulbs 2 inches away from top of plants at all times, ide start with 2weeks 24/0, then 2-3 weeks 18/6 then flower.
Only thing is if u flower with the same amount of light it will take much longer and ur yeild will be rubbish, if u can get a 250 or 400w hps ul get great results, inother words u can veg with low watt cfl but to flower u should realy have more light!!
Hope that helps u m8, if u need anythign just msg me, good luck.
