This is the beauty of seeds—often, you can tell which plants or genetics will thrive right from the get-go. This will help you determine which plants you want to take cuttings from for clones or for breeding if you want to create a seed bank of your own.
However, a type of cannabis called Cannabis ruderalis, which developed in extreme northern conditions without much sunlight, will begin flowering once the plant reaches a certain age—they automatically start flowering regardless of the amount of light they receive, hence the name “autoflower.”
A seed has germinated once the seed splits and a single sprout appears. The sprout is the taproot, which will become the main stem of the plant, and seeing it is a sign of successful germination.
The main drawback to growing from seed is there is no guarantee as to what you’ll end up with—if you buy a regular pack of cannabis seeds, it will be a mix of males and females. You’ll need to sex them out (more below) to identify the males and get rid of them, because you don’t want your females producing seeds.
Finding a cannabis seed in your stash is not ideal, but we’ve all been there before. Although much less common than it once was, it still happens. Sometimes you’ll notice one when grinding down some flower, or you’ll see one pop, spark, and crackle from the heat of a lit bowl.
Even if your seed sprouts fast and grows vigorously, it still has roughly a 50/50 chance of being female and producing buds, instead of turning out to be a male.
Also, autoflower plants are small—perfect for closet grows or any small grow, or growing outdoors where you don’t want your neighbors to see what you’re up to.
For many years, people had to choose between the benefits of indica or sativa. But you can also grow hybrid plants, which blend the qualities of sativa and indica into one plant. Hybrids usually are dominant one way or the other – indica or sativa – but also produce the effects of the other kind of plant.
Seeds should be kept in a cool, dark, dry place. Do not expose seeds to sunlight or they may sprout. Do not expose seeds to moisture or they may sprout as well. Seeds should be stored at room temperature. Exposing the seeds to extreme cold or heat could damage the seed so that it can never be used.
So you’ve decided you want to grow cannabis. One of the most important and earliest decisions you’ll make is which seeds to use. A good seed contains the essential ingredients for a healthy, potent plant. Learning how to choose cannabis seeds doesn’t have to be complicated – learn the basic facts here.
How to Spot a Healthy Seed
Healthy marijuana seeds are dark brown, black, or some combination of both. We’d recommend you don’t use green seeds. Green seeds usually aren’t yet mature enough to sprout. Both bigger and smaller seeds will work. Indica seeds tend to be bigger-sized than sativa seeds. Another way indica and sativa seeds differ is in their patterns. Seeds that are brown and black are most likely indica, while the seeds that are a single color are generally sativa.
Another thing to consider, especially if you are a novice grower, is that indicas take less time to mature than sativas. Indicas are considered a hardier plant that can withstand more stress so they are more forgiving to novice growers who tend to make a few mistakes on their trial run.
Seeds are only produced by female cannabis plants after a male plant pollinates them. To grow your own seeds you will need the female plants that produce the seeds, as well as a male plant to fertilize the female plants. It’s as simple as placing the male plant near the female plant you want to fertilize. Seeds will appear in about 4-6 weeks. This can be a complicated process, with a lot of uncertainty, so many people choose to purchase feminized seeds instead.
Seeds can be male or female, but most people only want to grow female seeds. Why? Because female plants are the plants that produce buds. Most seed companies sell “regulars,” which contain male and female seeds. However, they also offer only female seeds, referred to as feminized seeds. There is a big price difference between the two, but its worth it to spend the extra money to make sure that you are working with feminized seeds so that you do not waste your resources growing male plants that don’t produce the results you want.
Feminized marijuana seeds are the “easiest” seeds to grow after the Auto-flowering varieties. Feminized marijuana seeds mean that they are treated to make them female marijuana seeds (hence the name feminized) so that all the marijuana seeds can be used to get flowers. Breeders usually sell feminized marijuana seeds for their strains because they are easier to grow than regular female marijuana seeds and are too unstable to reproduce, although some people use female plants from feminized marijuana seeds to get cuttings, it is advisable that they use female from Regular marijuana seeds. It is recommendable to start growing with Feminized marijuana seeds, this will mean that the final plant won’t have any undesirable surprises like marijuana seeds reducing potency since there are only female marijuana plants.
As a rule of thumb, you cannot know what sex the Marijuana seeds are by just looking at them. Even Feminized Marijuana seeds are 99.99999% certain to be female. The only way you can find out what marijuana seeds are female is by germination. After two or three weeks, you will see the male or female flowers and this is the only way to know for sure what marijuana seeds are female.
