More commonly, growers use the paper towel method. Dampen a paper towel, ensuring it isn’t soaking wet. Place this on a kitchen plate and put the seeds on top, then put another plate upside-down on top. A moist, dark, warm environment allows the seeds to sprout. Check on the seeds once a day; after germinating, you should see a white taproot emerge.
Are you still unsure about your cannabis seeds? You can always do a floating test to see if they’re healthy. By the way, this method works for numerous plant seeds and not just cannabis.
Cultivating marijuana is a bit of a learning curve, so don’t worry if you mess up your crop from time to time. It will only get easier with time.
Method #4: The Germination Test
One way around this is to purchase feminized marijuana seeds. In theory, all seeds in a feminized bunch will be female – unless you buy from a disreputable grower. Unfortunately, there’s no way to tell whether a plant is male or female simply based on the seeds.
If all else fails, it’s time to germinate. You might have no idea whether your seeds are healthy but attempting to grow them is an easy final test that will separate good seeds from duds.
The best feminized seeds aroun…
For this test, you will need a cup, glass, or bowl of warm water. It should be quite warm, but not hot. It also works best with spring water or distilled water.
One of the best ways to ensure all your plants end up being female is to start with feminized cannabis seeds from a trustworthy breeder.
Bag seeds you randomly find in your buds aren’t supposed to be there, so that means that the genetics are a toss-up. Even if the seeds started with good parents, there’s no telling how high or low the quality will be. Unfortunately, the only way to find out is to grow it… Some growers win the genetic lottery, but many others lose out.
However, that’s not how genetics works most of the time. Without intensive breeding and backcrossing, when you mix two random plants you often end up with only a fraction of the seedlings capturing the best of both parents.
That being said, sometimes bagseed is all you have, and lots of growers get lucky!
If you talk to breeders, you’ll learn that when you breed two “star” strains together you don’t always get what you’d expect. It seems like every one of the seedlings (or at least most of them) should be capture the best qualities of both their parents.
Seeds are a little nugget of genetic material than can hopefully grow into a plant. And like all other genetic material, it doesn’t last forever! Although seeds can be viable for quite years and years after they’re first produced, the chances of them successfully germinating goes down over time (and old seeds also tend to take a lot longer to germinate than fresh ones). The resulting seedlings are also more likely to be slow growing. But sometimes they sprout like they were born yesterday!
Did you know that the “stripes” on cannabis seeds are actually part of a protective coating? The “pale” seeds in this photo are actually just regular seeds with the coating rubbed off!
