veging under cfl's would i benefit any more if i put more cfl's on the back and both sides of the grow ? otherwords having the plan get light from all sides .. also going to put some side light on them while they flower...shouldnt i get a slightly bigger yeild ?
Yes, basically more light = more growth. Are you going to be flowering under a HID or CFL's?
If your flowering under CFL's use as many as you can to get the best possible yield.
If your flowering under an HID you could use CFL's as supplementary side lighting for a larger yield.
Now that I have been trolled into thinking CFLs are so awesome, Maybe there should be a 1000 watt CFL and people could have a 1 bulb solution. But yes, in the mean time, you will just need to keep adding as many of those little bulbs as possible.
