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.
If you’re looking for more precise, science-based methods to tell your plant’s gender, there are several labs that can sex your plant right after germination – eliminating the lengthy (usually around 6 weeks) wait to learn its gender. Portland, Oregon start-up Phylos Bioscience is in the business of studying cannabis genetics, and they sell a “plant sex kit” that’s pretty simple to do, even for the not scientifically-inclined. Simply press a cotyledon, or embryonic leaf, onto the kit’s filter paper and send it to their lab. They then test the leaf for the “Y” chromosome to determine its gender, just as would happen for a human male.
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.
What are Feminized Seeds?
While it’s basically not possible to determine the sex of a seed from a random bag of seeds, a practice known as feminizing is becoming quite popular. Feminized seeds are selectively bred to produce female plants, however, some growers do worry about some feminized seeds turning into hermaphrodites.
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 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.
How much time you want to spend figuring out the sex of your cannabis plants really depends on how much time and energy you’d like to devote to growing your own marijuana. If you are a medical cannabis patient or caregiver, for example, and need to know what kind of cannabis you are getting every time, buying feminized seeds from a trusted seller is the way to go. But, if you have some time, consider yourself a green thumb, and want to experiment with your grow, you could simply plant your seeds and see what comes up. Happy growing!
Cannabis enthusiasts have been trying to find out how to determine the sex of a marijuana plant by the seed for ages. Unfortunately, there is no way to tell if the seed will produce a male or female plant by just looking at the seed. Regular marijuana seeds have a 50% chance of being female, so out ten seeds, growers can expect that 5 of them will probably produce female plants.
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.
A high-quality marijuana seed has a dark color, typically a shade of brown, grey, or black. It should have tiger-like stripes or spots on the entire surface of the seed. If the seed is green or white, it is immature and is not likely to germinate. In the rare circumstance that an immature seed germinates, it takes much longer than it would for a mature seed.
Can You Tell if a Marijuana Seed is Female?
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.
Quality marijuana seeds have specific characteristics that set them apart. Unfortunately, they can be difficult for consumers to find since most growers avoid seed production in their plants at all costs. Even when a rogue seed is present, it rarely grows mature enough to germinate. Though it is challenging to identify a quality seed for even the most experienced growers, it is vital to be able to do so when using seeds to grow marijuana. Below is an overview of the characteristics of a high-quality seed.
The most obvious thing a person can do to show seed quality is to germinate the seed. If the seed sprouts within 5 days, it is a viable seed. It will still take time to find out if the plant will be male or female and whether the strain is high quality.
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.
