I started out with 24hr for the first 3 or 4 days then I switched it to 18/6. Im being told having it on 24hr will obviously help it grow faster during veg. then having the lights off help the roots grow? I dno if thats correct or not.. But If 24hr is better can i switch it back without stressing the plant?

Switching the light cycle will definately stress the plants. Anything over 18 hours is a personal choice thing. The only time I would do it (during veg) is if I lived in a climate where it was so cold that the lights were better left on to help keep the room warm enough not to have to use extra heating when lights were off.

20/4 works well i have had plants start to flower at 18/6 (i know weird huh) save some power. i keep clones and seedlings under 24 though
