If I do a scrog using CFL lights should I have some lights under the screen during veg? CFLs don t have the light penetration like HIDs.

Normally two weeks into flowering I would just cut off all the branches and leaves underneath the screen and let the plant concentrate all its growth on the top of the screen. So during flowering all of the lights will be at the top of the screen.

But durgin Veg Its a good idea to have some CFL lights under neath the screen?
