Not sure why but two strains I now have have different bios on flowering times. But after a while or should I say after two rounds of flowering they started finishing at the exact same time. Not sure but maybe it is like women that live together and start to bleed at the same time. Seems odd but true in this case. Two different strains one sativa dom and the other an indica. So for what it is worth. Can't find many strains that have such a short flowering period. I have done many and these two finish almost before you get ready to clone which I did this last time 4 days after I started the cutting. Actually i am lieing. I cloned two weeks after the start of harvest.. I hate to look lazy you know but hey I am sure you pots heads will understand. LOL...
