light help

right now i have 3 13watt cfls and a 18inch 15watt fluorecent. i have the timer at 18 on 6 off for three plant and im just woundering think that will be good to start out with and what i might be getting from the plants whan i start the flowering? oh yeah the plants are around 3 to 4 mouths old and health as can be. thank you all peace

Sounds like you might need more lighting go for full spectrum lighting for the germination and vegetation stages.
And your yield will depend on the strain, the grow conditions, how many nodes("bud sites") you have, and whether or not you topped off the plants before going into flowering.

Wait are you flowering now?

no im not flowering yet..and yup i have been clipping the tops

oh yeah i have the fullspectrum cfl's

you might need alittle more lighting, you could just upgrade the CFLs to 27s, and get a couple more...

good luck
