When to harvest outdoor marijuana 2013?
If meteorology is right, this 2013 we should percieve that our plants end their flowering from 10 to 15 days later. For an indica stran that should be harvested rounding September 30th maybe this year ends at half of October. Sativa plants may not be as afected as indicas because they still depend from August light to induce them to flowering. However won't be strange to percieve a 10 days difference from one area to another.
