BREEDERREGULARSEEDS

Males and females follow slightly different clocks once flowering begins. In a room started from regular cannabis seeds, males usually show their sex first and release pollen one to two weeks before most females become fully receptive, a mismatch nature uses to ensure cross-pollination within a population. For growers, this head start is useful: it offers a window to remove males before any damage is done. Watching the tallest, fastest plants closely often reveals them first.
