Are These Cannabis Seeds Good?
Growing with bad marijuana seeds is particularly harsh on growers of all levels.
This is mostly because it’s tough to pinpoint when the seed itself is the actual problem. Most growers will blame themselves for a problem that shows up in their grow long before they assume it’s the seeds.
The term ‘bad seeds’ usually refers to any type of seed that has a significantly higher likelihood of causing problems in a grow. I’ll cover the most common reasons for bad seeds in this tutorial!
These cannabis seeds were germinated between two wet pieces of paper towel!
These are pot seeds you might get from a friend, or maybe you have them stashed somewhere and forgot how you got them. In either case, if the shell of the seed looks beat-up, it may not germinate as well or quickly as seeds that were stored in good conditions.
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!
Check out the picture below. We sprouted all the plants at the same time. The tub on the right has seeds that were planted within a week of receiving them in the mail. The tub on the left has a very popular strain with award-winning genetics… but the seeds were more than 6 years old from when we first bought them. Even though they were all put into the tank at the same time and the new seeds grew like crazy, the seeds on the left got outpaced by algae – only one sprouted and though its roots keep growing and growing the actual never got any bigger than two round leaves even after a month!
Pale or Flimsy Seeds
When I first started growing I was told that good cannabis seeds needed to be very hard with dark tiger striping. If you could crush it between your fingers, it was a bad seed, or so I was told. This has not been my experience at all!
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!
Over the years, some of my very best plants came from flimsy, light brown seeds that very likely would have been easy to crush between my fingers.
So I’m a big believer in the fact that if you put the seed in the ground and a fast-growing healthy seedling comes out of it, it was a viable seed! Don’t toss a seed you are really interested in just because it’s a little pale; give it a chance (I’m talking more about tan seeds, it’s very unlikely a yellow seed will sprout)!
Note: Although the hardiness of the seed was likely important in the wild, cannabis growers have been breeding plants for generations to make good buds, not seeds! We growers strive to provide an ideal germination environment that lets almost any seed germinate successfully. As a result, we haven’t been breeding for seed hardness. Just like a teacup poodle hasn’t been bred to be strong, cannabis seeds haven’t been bred to be strong. They have other qualities we love
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.
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.
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.
Bag seeds are a wildcard! You never know what you’ll end up with!
So depending on how the seed was originally made, bagseed often has a lot of variety. Even if the buds you got were an incredible quality, it doesn’t necessarily mean that the seeds will produce buds like that. If you’ve ever gotten involved with breeding or growing other types of specialized plants like roses, hops or even apples, you’ll know that seeds rarely breed “true” to the parents, and cannabis isn’t any different.
That being said, sometimes bagseed is all you have, and lots of growers get lucky!
Hermaphrodite or Male Plants
If a cannabis seed was produced with a male doing the pollinating, it means that about half of the resulting seeds will end up being male (which you don’t want, because only female flowers turn into bud). In that case, you want to determine the gender of your young plants as soon as you can so you can toss all the male ones before they start making pollen sacs.
If growing with seeds that were produced without a male plant around, the seeds sometimes end up being hermaphrodites, which means they grow both male pollen sacs and female flowers (again, something you don’t want).
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.
Sometimes It’s Random!
Even if you’re starting with the best, most fresh seed stock, occasionally you’ll get an individual seed or plant that just doesn’t grow as well or quickly as the others, or maybe you’ll get a super awesome seedlings that just starts kicking butts and taking names from its first moment.
Natural variation is totally normal! It’s always a good idea to sprout at least a few more seeds than you need in case you happen to run into a runt, or some other expected problem! If all your plants are healthy and growing fast except one, you can blame the seed!
10 Markers of a Quality Marijuana Seed
If you’re looking to start growing your own marijuana, the first place to start is with the seed. What should you look for? How can you tell a good cannabis seed from a dud? Chris Bond tells us.
So, you’ve decided to grow your own marijuana from seed. How do you know if those little, round nuggets in your hand will grow up lush and produce beautiful, productive buds? How do you know if they are duds? While ultimately the genetics will determine the destiny of those little weed seeds, and proper care will help them to realize their full potential, there are some markers you can assess to see if what you have is quality seed, indeed.
What to Look for in a Cannabis Seed
While all cannabis seed is not identical in color, there are some consistencies. Healthy, viable seed will be light to dark brown in color. Seed that is light green or even whitish in color is underdeveloped and should be tossed out. Healthy seed will also have a burled or turtle shell-like pattern on its seed coat.
A quality cannabis seed will have a waxy, protective coating. Seeds that appear dull are probably not as viable and should be avoided if given a choice.
Quality cannabis seed will look like a plump teardrop. Flat or misshapen seeds will not likely produce quality plants.
Quality seed will be firm. Cannabis seed should have a strong seed coat protecting the pre-emerged life inside. Any seed that is tender, pliable or squishy should not be planted; poor results will follow if attempted.
Size is relative, but if you are able to compare several seeds at once, the higher quality seeds are larger. When it comes to seeds, less is more. The fewer seeds that comprise any given amount, an ounce or a gram for example, is generally an indicator of higher quality seeds. The biggest seeds within a species generally have more energy stored within them and have a greater potential to mature into a productive plant. Note that indica strains tend to produce larger seeds than sativa strains so make sure the comparison is made among like seeds.
Weight often goes hand-in-hand with size, but heavier seeds are generally of higher quality than lighter ones. The older a seed gets, the more potential loss of moisture and nutrients, reducing its overall weight. Damaged seed, which has been cracked can potentially lose those same necessary qualities.
#7 Float test
Quality seeds will sink in water. In glass or vessel, place room temperature water deep enough to full cover the volume of seeds to be tested. Place your seed or seeds in the water. After a couple of hours, anything still floating, should not be considered a quality seed. Soaking seeds will allow moisture to cross over the protective membrane and signal the seed that it is time to grow. As such this test should not be performed if the intent is to store the seeds after testing as it may render otherwise quality seed unviable if not meant to be immediately germinated afterwards.
You may not have access to see or have verified information on the storage conditions of seeds, but if you can find this out, it is critical to maintaining quality seeds. While cannabis seeds can be viable for over 10 years in some instances, the best seed in terms of productivity is not more than 12 to 18 months old. It should have been stored in dark, cool and dry conditions to prevent mold or the onset of any fungal issues. Storing in a freezer can prolong seeds as well, essentially suspending time.
#9 Age at harvest
This is another aspect you, the buyer may not be privy to. Quality seed is harvest when fully mature. If seed was collected before the plant was able to load as much stored energy into it as possible, then that seed will be starting out life in a deficit. Color, as referenced above can be an indicator of whether or not a seed was harvested at the appropriate time.
You get what you pay for and a cannabis seed is not exempt from this maxim. Quality seeds are not cheap (at least when compared to other agricultural seeds). This isn’t to say that inferior seeds can’t be overpriced, but if you find cannabis seeds proclaiming excellent genetics for sale at a price that seems too good to be true, caveat emptor.
This is not meant to be a definitive list, as new varieties of cannabis emerge on the scene all the time that may have “normal” traits that would otherwise be viewed as deficiencies in other strains. As always, do your homework, ask other growers who know and buy your seeds from a reputable source.
