I have always kept my plants from seed to about half the height that I want them under 24 hours of light . Is there any scientific evidence showing that a 18/6 schedule is more beneficial to the girls ? I know some of you know just from experience .
I have grown the dreaded awful flowers with photo periods and I dont think I could have gotten anything extra out 18/6 after they started flowering. Well other than what RbtAsq said. lol That would be a great experiment if they ever stabilize the damn things so 2 are the same phenotype
