your title is going to get you zero veiws/replies, i only had a look out of complete utter confusion, vegg til harvest?!?!
are oyu talking about veging spectrum lights till harvest? i.e 6500k all the way instead of switchin to 2600? you can do that if you want, but your plant iwll not be bale to use all of it and you will have better results using the correct spectrum.
keep them nice and close 1-2inch
how many watts are your lights?
i suspect only 5 CFL will not be enough to support a 5 plant grow
