Good info, and thanks for the youTube suggestion.

I'm on my first indoor grow and do have a few other questions and would appreciate anyone's help... Here's a link to my grow thread where I have pics and a couple questions. Thanks a bunch!

their is atechnique that involves 12 off 24 on, inkepping wit 12 dark cycle but allowing extra growth during 24 hr on, its on this forum under advanced lighting techniques in the faq check it out if u interested but 12/12 is the way 4 me if it aint broke dont fix it

Yeah, I was wondering if you could alter the 24 hour day for a plant... You know, if growing weed was allowed as a science experiment, I'd have been all over the science fair projects as a kid!

Keep it simple dude. 12 on 12 off. First indoor grow you will have plenty other things to worry about.lol Good Luck.

i know if u do 13/11 u have a larger yeild/longer flowering wait due to the 1 hr loss in the 12/12 due to more light energy, if u do 11/13 you will have a less flowering period wait and a less yeild. make sense to u ppl? anything outta of this is unknown on how it will affect flowering but test have been done with the 13/11 and 11/13. remember more light hrs (13/11 larger yeild longer wait/ 11/13 less wait less yeild.

i found that 13 11 works best. i know in nature plants do not get 12 hours uninterupted dark. not where i live anyway. so i guess its just a rule of thumb. with room for interpretation. ive tried 12 12 then 11 dark 13 light, then 13 dark and 11 light. i found that in veg 18 hours light 6 dark works best and in flower i go with 13 dark and 11 light. i dont think that when it comes down to it the hour really makes it or breaks it.
