Seeds can remain viable for three to ten years if stored properly, but more and more seeds will fail to germinate as time passes. Older seeds will take more time to germinate, so growers should use the float test before assuming the viability of their stored seeds. They can speed germination by soaking the viable seeds in water mixed with a few drops of hydrogen peroxide for 24 hours. It is important to watch them closely for signs of opening, as they will need to be removed immediately to avoid drowning.
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.
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.
Germinating Old Seeds
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.
There are several visual indicators that can give a person an idea about the quality of a marijuana seed. Some details are easy to spot while others take a higher level of scrutiny.
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.
Out of the other 3 plants that were potentially female, all 3 have shown sex and guess what, all 3 are Females.
If the sprout comes out of either SIDE of the seed, it is a MALE.
If the sprout comes out of either the TOP or BOTTOM of the seed, it is a FEMALE.
I may have the answer but would like for other growers to please try this out and confirm if it works for them.
Firstly, I’m pretty new to posting on this forum so hopefully I posted this in the right category.
I always see this question everywhere, "Can you tell if a seed is male or female?"
To tell if a seed is male or female, you must first germinate it.
Once the seed sprouts, you need to look where it sprouted from.
