Guide to Buying Cannabis and CBD Seeds


Whether you’re looking for information about the legality of buying cannabis seeds, or you need to know when is the best time to grow cannabis seeds, we’ve got you covered. We will help you navigate everything you need to know about buying cannabis and CBD seeds in this guide to buying cannabis and CBD seeds.

The first thing we need to talk about is its legality. Cannabis and CBD seeds are legal to purchase in your state as long as you have legalized the use of hemp-derived products that contain no more than 0.3% THC on a dry weight basis. Because cannabis seeds contain such a low amount of THC, they can be legal to purchase in your state if your state has legalized hemp-derived products.

If your state has banned cannabis and CBD products unless you have a medical marijuana card, then you can only purchase cannabis and CBD seeds by possessing a medical marijuana card. Additionally, cannabis and CBD seeds may not cross state lines and cannot be brought into the United States if bought in another country.

Where to Purchase Cannabis and CBD Seeds

If your state has legalized the use of hemp-derived products, then you can purchase seeds from a local dispensary or a seed bank. A seed bank is a company that preserves seeds and sells them to both residential and commercial growers.

A seed bank offers the largest variety of quality seeds, but the seeds may not always produce quality cannabis or CBD plants. Like finding a reputable retailer for CBD products, we recommend purchasing cannabis and CBD seeds from a retailer you know and trust.

Cannabis and CBD Seed Pricing

A pack of cannabis and CBD seeds will contain between 10 to 12 seeds. The average price of a pack of seeds can be as low as around $40 but can increase depending on the quality and type of seeds you’re buying—especially if you are purchasing feminized or autoflowering seeds.

These seeds cost more because of the labor that goes into breeding these seeds. On the high end, don’t be surprised to find feminized or autoflowering seeds running as much as $500!

What Type of Environment Do I Need to Grow Cannabis and CBD Seeds?

The environment you need depends on if you choose cannabis or CBD seeds. Strains will either be Indica or Sativa. Indica strains contain CBD, while Sativa strains contain no CBD.

CBD seeds can grow in cooler environments and don’t need as much warmth as Sativa strains. You can grow CBD seeds outdoors, while cannabis seeds will grow best indoors, where you can control the warmth of the environment.

Cannabis and CBD seeds will need nutrients to help the seeds germinate into strong, quality plants. Sativa seeds thrive in nitrogen-rich soil. The soil should be nitrogen-rich and have secondary nutrients like potassium and phosphorous. CBD seeds don’t require specific nutrients to grow into strong plants.

Finally, humidity determines the environment you need to grow cannabis and CBD seeds. CBD seeds don’t need as much humidity as cannabis seeds. CBD seeds can grow in cool, dry environments that have little humidity.

Cannabis seeds require warmer environments with moderate humidity levels—generally between 40% and 60%. If you don’t live in an environment that is warm with high humidity, you can create an environment that is suitable for them by growing cannabis seeds indoors with a heater and by spraying the leaves with water to mimic humidity.

How to Choose the Best Cannabis and CBD Seeds

One term you frequently see when purchasing cannabis and CBD seeds is “genetics.” Genetics refers to the history of the seed, where the seed came from, and what kind of breeding it went through. Genetics is important because it will determine the type of cannabis plant the seed will grow.

Don’t be afraid to ask the seed supplier about the genetics of the seeds. If the genetics are considered “unstable” by the breeder, this means that the seeds’ origin is unknown. This can be risky when purchasing seeds needed to produce quality cannabis plants.

The seeds should contain information that lists where the seeds came from and if the seeds were crossed with other breeds. If the seller cannot provide information about where the seeds came from and what they were crossed with, they may have poor or unstable genetics. We recommend avoiding these seeds as they may not produce quality cannabis plants. The plants may be weak, sickly, or less potent.

Think about the features you enjoy when using cannabis or CBD products, and try to choose seeds that produce those products. This will guarantee that you grow the same quality products that you enjoy.

Regular, Feminized, and Autoflowering Seeds

Cannabis and CBD seeds will be regular, feminized, or autoflowering seeds. It’s important to understand the difference between these seeds so that you know what to choose and why.

Regular Seeds

Regular seeds are a combination of male and female seeds. Male and female seeds are important for different reasons. Female seeds produce female plants that will flower. A female cannabis plant produces cannabinoids like CBD and THC.

While male plants technically produce CBD, it is much lower and less potent in males, which is why many growers choose female plants for cannabinoids.

Male seeds are important for gene pool diversity. Rather than have a female cannabis plant self-pollinate, male plants are used for pollinating, which will help diversify the genes in the plants grown from the seeds.

Feminized Seeds

Feminized seeds are female-only seeds that will produce only female cannabis plants. Feminized seeds are the easiest to grow because they are guaranteed to produce female cannabis plants. If you know you don’t need male cannabis plants and only need cannabis plants that flower, you should choose feminized seeds.

Autoflowering Seeds

Plants require water and sunlight to grow and produce flowers. With autoflowering seeds, they produce plants that will automatically flower due to their age—not the amount of sunlight they receive. Autoflowering seeds are ideal for those who may not be able to dedicate as much time and attention to their seeds as they would like. The seeds can produce plants ready to harvest in less than three months.

How Many Cannabis Seeds Should I Buy?

Cannabis seeds are no different than any other type of seed when it comes to sowing and harvesting. Not all seeds will germinate, so you’ll need to account for some of them not producing.

On average, you should account for approximately 25% of the seeds you purchase and sow to not produce. You should always purchase more seeds than you need so that you can account for non-production.

Another factor you need to consider is discarding male cannabis plants. Unless you need a male cannabis plant for breeding, you’ll likely only want female plants. When purchasing regular seeds, you get a combination of male and female seeds, so you’ll need to discard the male plants.

We recommend purchasing roughly 25% more seeds than you need to account for non-production and male plants. Feminized and autoflowering seeds won’t produce males, but they can still be non-productive.

You should still account for approximately 25% of female and autoflowering seeds being non-productive so that you have enough seeds to produce the number of plants you want.

A Quick Recap


Cannabis and CBD seeds are a great way to produce your own hemp-derived products, especially if there is a breed of plant that you enjoy the most. It doesn’t take much time or equipment to successfully grow the cannabis plant of your choice.
