Seed to Harvest: Part 2- Getting Genetics: Clones, Feminized and Unfeminized Seeds
Deciding what strains to grow will only get you halfway to starting a garden. Once you know what to grow you have to figure out how to get it.
There are a few ways that cannabis growers share and get genetics. Clones can be cut from plants during the vegetative cycle, and seeds can be bred through one of two kinds of pollination.
Most people know that the female marijuana plant produces the buds, or flowers, with the concentration of active cannabinoids, so it’s not a big surprise that cannabis is naturally a dioecious plant, meaning there are separate male and female plants. But have you ever thought about how rare that is?
Ninety percent of plants are monoecious or hermaphroditic, meaning each individual plant has both male and female reproductive organs. Cannabis stands with Ginko, Juniper, and Willow as a plant that has evolved into dioecy to prevent self-pollination and encourage genetic variety through cross-breeding.
Naturally, cannabis is bred by fertilizing a flowering female plant with the pollen produced by a male plant. The seeds produced represent a cross between the genetics of the two parents. Natural, regular, or unfeminized: whatever you call them, when these seeds sprout, they yield about half male and half female plants. Growers of natural seeds have to monitor their plants at the beginning of the flowering cycle in order to identify the first signs of sexual characteristics so that they can identify the males from the bud-producing females.
For a lot of growers, the benefits of feminized seeds are obvious: you can obtain seeds guaranteed to produce female plants. This meant that you don’t have to sprout so many seeds at a time just to get the bud-producing females that you want. You don’t have to worry about introducing pollen into your garden and compromising your sensimilia.
Anyone who’s ever purchased marijuana seeds is likely familiar with the feminized variety, but do they all know how seed producers can control the sex of the seeds? While cannabis is dioecious, it also retains the ability to exhibit hermaphroditic characteristics under stress as a survival technique. Environmental stressors, like light cycle interruptions, can trigger female plants to “herm out” and grow feminized seeds.
Feminized seeds were produced this way in the olden days, and many growers believe they yielded strains that were predisposed to intersexuality (they would “herm out” more quickly than other, more stable, strains). Over the years, the technique has been refined in an attempt to increase stability, and now breeders produce commercial feminized seeds by exposing female plants to colloidal silver (which is pure silver) or gibberellic acid (a natural hormone) to cause hermaphrodism, allowing the plant to self-pollinate.
