W hen it comes to growing cannabis, sex is important. Not that kind of sex! We’re talking gender, as in being able to discern male from female. The reason for this is simple enough: only female seeds produce flower, also known as the buds you might have in your stash as we speak.
If you have some experience growing cannabis and would like to bend a crop to your will to ensure that the seeds will be female, there are a few feminizing methods you might try. One such technique is to literally stress out a healthy female plant by interrupting the light cycle during flowering, called Rodelization Feminizing.
If what you’ve got is a handful of seeds, it’s pretty much impossible to tell which ones are male or female. The only way true way to tell the plant’s gender is to plant some seeds, then wait. After a period of several weeks, it will begin to pre-flower, or form a small bud in the crux of a branch. One of the first signs your cannabis plant is female is the appearance of pistillates that are wispy and generally white in color.
There are many companies that sell feminized seeds, but, buyer beware, do your research to make sure the seller is reputable, especially if purchasing online. Thanks to modern technology, most feminized seeds from reliable brands will be 100% female as advertised – but that doesn’t mean there aren’t people selling low-quality seeds out there.
In the colloidal silver feminizing method, distilled water is mixed with pure silver and sprayed on female plants. This method works best when the plants are flowering. This results in pollen sacs being formed, which will allow the seeds to produce female plants.
When growing marijuana, it is important to identify male plants as early as possible. Just one male plant can pollinate an entire field, so it is critical that male plants are removed before they develop pollen sacs. There are certain signs that a young marijuana plant is male, including the following:
Preflowers are the earliest sign of a marijuana plant’s gender. Between four and six weeks, nodes will develop at the joint where a plant’s stem meets the stalk. Female plants develop white hairs at the internodal joints while male plants develop rounded internodal sacs that fill with pollen.
The float test is a more scientific approach to determining the quality of a seed. The test involves filling a drinking glass with spring or distilled water and placing the seeds inside of it. Allow the seeds to soak for one to two hours before determining quality.
What Does a Male Cannabis Plant Look Like?
After the time has passed, seeds that float can be considered poor quality and discarded. Seeds that have sunk to the bottom of the glass are healthy, high-quality seeds. Once the test is complete, the seeds need to be germinated right away. Their shells will be soft from soaking in the water and will not survive storage.
A lot of information can be gleaned from the texture and hardness of a marijuana seed. After visually inspecting the seeds, growers can pick them up and feel their shell for the following:
Ask any experienced grower how to produce a hardy marijuana plant and they will say to start with a seed for a good strain. Lighting, soil, nutrients, and water play large roles in the final yield, but starting with a high-quality seed gives growers the best genetics with the highest potential yield possible. Most people find their first seed mixed in with marijuana, but most of these seeds are low quality and may grow to be male plants. The best way to get high-quality seeds is to purchase them from a reputable marijuana seed retailer.
While seeing and feeling a marijuana seed can give growers a lot of information, it is not always accurate. Even the best-looking seeds can be duds, especially if they have been frozen. Below are a few things growers can do to better determine the quality of their seeds.
