Hermaphrodites- Although sometimes naturally occurring, hermaphrodites are usually triggered by stress (or chemically with Gibberellic Acid). In a typical garden set-up, you should remove and destroy a hermaphrodite whenever you see one in order to save your precious garden. However, they are known to be the “right-hand man” in creating feminized seeds. When a female turns into a hermaphrodite it will pollinate itself creating seeds, but it still keeps its XX chromosomes; theretofore, it’s offspring will only have XX chromosomes which is guaranteed female.
Male Flower (Mid-Stage)-The sole purpose of a male cannabis plant is to pollinate female cannabis plants in order to create seeds. To grow the best cannabis it is essential to remove and destroy all male plants. When males pollinate females, the female uses most of her energy into creating strong, healthy seeds. In turn, she will have lower amounts of THC and overall poor quality. Males are more often to appear in lower pH conditions, so it is important to keep your soil between 6.5 and 7 at all times (if you are using soil). You can force a plant to turn male by applying Gibberellic Acid. Depending on strain, most males will be your tallest plants, and usually appear very lanky. When growing Auto-flower, males normally show themselves first (around 20 days after germination). When cross-breeding, the newly developed seeds will usually have more of its mothers characteristics.
Female (Pre-Flower)-Female cannabis plants are often misdiagnosed, mistaking the stipules for pre-flowers. It is important to remember that the hairs should be white, and just because you see a white hair doesn’t guarantee that it is a pure female. Hermaphrodites are pretty common among cannabis plants, normally triggered by different types of stress (heat, light). Females normally take a few extra days to show signs of pre-flowers over male plants. Female cannabis is responsible for creating what we know as “bud”, which contains the highest amount of THC, CBN, CBD and other chemicals. It is possible to create female seeds (feminized), and there is also products on the market that “reverse” males into females (Dutch Master Reverse).
