how to prove my marijuana seeds are hemp seeds

Feminizing via the silver thiosulfate technique involves carefully selecting a nearly mature female plant, then spraying it with 50/50 mix of sodium thiosulfate and silver nitrate. This triggers a gender change, from female to male. Place this plant back with the others to pollinate other female plants, and female seeds are created.

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.

What are your thoughts on feminized seeds? If you’ve used them before, how did it go? Share your experiences in the comments below!

Despite the potential for hermies, if growing cannabis is more hobby than full-time endeavor, and you want to guarantee you’ll have some consumable product, knowing your seeds are female from the beginning is probably your best bet.

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.

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.

When it comes to growing cannabis, seeds can be male, female or hermaphrodites. Females produce the resin-secreting flower, and males make small sacs of pollen near the base of the leaves. Over the years, cultivators have learned that un-pollinated females (remember, males produce pollen) continue to make resin and flowers that have not been pollinated are much more likely to produce high-potency cannabis. But is there a way to know if a seed is female before growing?

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.

Here are a few tips to obtain quality seeds to begin with and to test them before planting to make sure the effort is worth it.

However seeds that crack or even completely crumble indicate poor health. Small cracks in the outer shell will signify that the seed is weak and not entirely healthy even before this test is carried out.

HOW DO THEY LOOK?

There is no doubt that nutrients, water, lighting and other needed external factors will dictate the quality of a grower’s crop, but ensuring the seeds they intend to plant are healthy enables their plants to receive the best start possible.

The more reliable the source that you choose to purchase your seeds from, the better quality they are likely to be. Let’s look at it this way, if you choose to buy some massive, crystal heavy buds from a medical grade dispensary and compare that to some stalk heavy, leafy and poorly grown cannabis grown in your friends basement, which do you think is going to smoke better and provide a more enjoyable experience?

Immature seeds are likely to have a green or whitish appearance, seeds of this colour are not likely to sprout and produce a healthy cannabis plant. Healthier seeds usually feature spots and stripes on their shells.
