A guide to buying cannabis seeds
The first couple months of the year is a great time to start planning your cannabis garden to get a head start on the outdoor growing season, which roughly runs from March to November, depending on where you live.
Navigating the cannabis seed market can be challenging when states have different degrees of legality. This guide will answer your questions on buying seeds so you can be on your way to growing your own cannabis.
Is it legal to buy marijuana seeds?
Marijuana seeds are considered a cannabis product just like flower, edibles, and concentrates. Their legality depends on which state you live in. People living in states with adult-use legalization can buy, produce, and sell seeds within their own state, but seeds can’t cross state lines. People living in states with medical marijuana legalization can only buy seeds if they have a medical card.
Seed banks exist outside of the US and can sell them for “souvenir purposes,” but it is illegal to bring seeds into the US and Customs will seize any cannabis seeds they find in packages or on a person.
Where can I buy cannabis seeds?
Many world-renowned seed banks are overseas in the Netherlands, the UK, Spain, and other countries where cannabis laws are less restricted. Seed banks provide seeds from a variety of different breeders.
In states with adult-use legalization or a medical marijuana program, you can buy seeds within your own state, either at a dispensary or through a specific seed company’s website.
How to buy cannabis seeds online
Before you purchase seeds online, you’ll need to figure out what strain you want to grow and what breeder you want to buy from.
Because US federal law still prohibits cannabis, it can be hard to find information on seed banks and breeders. Breeders who have a long history and positive reputation are usually a good place to start. To get an idea of what well-established breeders look like, check out:
- Sensi Seeds
- DNA Genetics
- Green House Seeds
- Southern Humboldt Seed Collective
- Exotic Genetix
You can also do some research and find an online grow journal that details the whole growing process of a specific strain from a particular breeder. Through these, you’ll be able to look over another grower’s specific notes and see pictures of the final results.
If you grow some seeds and like the results, try growing another strain from that same breeder and see how it goes.
How to buy cannabis seeds at a dispensary
Although this option is only available to people living in states with medical and adult-use legalization, buying marijuana seeds at the dispensary is far more straightforward. However, your options are more limited.
Dispensary staff should be able to give you information on the seeds they’re selling, but keep in mind that a lot of dispensaries focus on selling flower and end-products. It’s a good idea to call ahead and talk to staff to see if they are knowledgeable about seeds and can give you specific information on growing.
How to look for quality genetics when buying marijuana seeds
Breeders talk about “unstable genetics,” meaning that a seed’s origin is unknown. Make sure that when you buy a packet of seeds that it or the breeder who produced them can list where the seeds came from and how they were crossed and/or backcrossed to get the seed that you hold in your hand. If you can’t get a seed’s history, it could be anything and the result of poor breeding practices.
An inexperienced breeder might cross a male and a female one time and sell the resulting seeds as a new hybrid strain, but professional breeders usually put their strains through several rounds of backcrossing to stabilize the genetics and ensure consistent plants that reflect those genetics.
Which strain should I grow?
Even one weed plant can produce a lot of buds come harvest time, so make sure you grow a strain you like. Note strains you enjoy when you pick something up at the dispensary or smoke with friends, and look for seeds of it when you want to start growing.
Some strains are easier to grow than others because they are more resistant to mold and pests, so if you’re new to growing, you may want to try an easier strain to start.
Some strains also take longer to grow than others. Depending on whether you’re growing indoors or outdoors, you may want to grow a quicker marijuana strain if you live in a climate that get cold and wet early in the season. For example, indicas are known for having a shorter flowering time than sativas.
All of this information should be available to you when buying quality seeds.
What’s the difference between regular, feminized, and autoflower seeds?
If you buy a packet of regular seeds, they’ll come with a mix of males and females. A lot of cultivators prefer to grow these because they haven’t been backcrossed—essentially inbred—as much as feminized or autoflower seeds. You’ll need to sex out the seeds once their reproductive organs show during the flowering phase and discard the males—because they don’t produce buds and will pollenate females, resulting in seeded flowers.
Seeds can come feminized, meaning you can just put them in soil and start growing for buds. These seeds are guaranteed to be bud-producing females and growing them cuts out the step of having to sex out plants and discard the males.
It also reduces the risk of having a stray male sneak into your crop—just one male can pollinate a huge crop, causing your females to focus their energies on producing seeds instead of buds.
Autoflower plants change from the vegetative to flowering state with age, not the changing of their light cycle. They have a short grow-to-harvest time and can be ready to harvest in as little as 2 ½ to 3 months from when you put the seeds in the ground. The downside is that, typically, they are less potent, but autoflower seeds are great for people who want to grow cannabis but don’t want to spend a lot of time doing it.
How much do marijuana seeds cost?
Cannabis seeds usually come in a pack of 10 or 12 seeds and start at around $40 a pack and go up from there. Some high-end genetics can run between $200 to $500 a pack.
Feminized and autoflower seeds will cost more because more breeding work was put in to creating them and they take less time for the grower to get buds.
How many seeds should I buy? Are they all going to survive?
When you grow any amount of seeds, a percentage of them won’t germinate, even if you get them from a reputable breeder. Always count on a few not germinating or dying off, or roughly 1/4 of the total you put in the ground.
When growing regular seeds, some won’t germinate and some will have to be discarded because they’ll turn out to be males. With feminized seeds, some won’t germinate, but a higher percentage of them will turn into flowering plants because there won’t be any males.
If you want six total cannabis plants to harvest for buds and are growing from regular seeds, start with about 4 times as many, or 24 seeds. Some won’t germinate and some will turn out to be males, and then you’ll want to discard down to the six best phenotypes. If growing feminized seeds, you can probably start with about twice as many seeds in this case (about 12); a couple won’t germinate, and then discard down to the six best phenotypes.
Make sure to always stay within your state’s legal limit of growing plants.
How do I buy strain-specific cannabis seeds?
Strains like Blue Dream, Gelato, and Original Glue have gained in popularity in recent years. Check out these resources on how to buy these types of cannabis seeds:

What seeds to buy? Cannabis seed banks typically categorize the seeds by sex, genetics, breeder, strain name and plant traits.
Cannabis Seeds by Sex
- Regular Seeds: Grow both male and female cannabis plants. The males are culled in sensimilla (seedless bud) production. Regular seeds are the best choice for breeders. They have sustained the cannabis genus through its natural evolution.
Read—Top 15 Best Regular Seeds
- Feminized Seeds: Grow only female plants. This is accomplished by breeding two female cannabis plants together. The resulting seeds can only inherit two X chromosomes—meaning all female plants. Feminized seeds are great for growers with strict plant limits and for cloning. Read—Top 15 Best Feminized Seeds
Cannabis Seeds by Genetics
- Sativa Seeds: Grow into tall plants with slender, elongated branches, sharp leaves and large colas. Sativa originates from subtropical/tropical zones including Africa, Southeast Asia, South & Central America. The plants have a naturally long flowering cycle that’s often over 10 weeks. Resistant to molds and diseases, sativas are great outdoor climate strains. They can grow to over 15 feet tall! High THC and THCV content. People who enjoy a stimulating “head high” effect prefer sativa cannabis. Read—Top 25 Best Sativa Seeds
- Indica Seeds: Grow short plants with fat leaves, thick stems and a stocky structure. Indica originates from temperate zones such as Afghanistan, Pakistan, India, Nepal and Morocco. Traditionally used to make hash, indica cannabis is the real deal dank—super sticky and dense. Indica grows like a bush and can produce large yields in a small area. The plants have a fast flowering cycle. They may require a low humidity climate to avoid mold problems. High THC and CBD content. People who want a relaxing “body high” stone prefer indica cannabis. Read—Top 25 Best Indica Seeds
- Hybrid Seeds: Grow crossbreeds of indica and sativa, in countless combinations. Hybrid cannabis seeds are able to grow tall sativa trees that produce the dank, heavy buds of an indica. Hybrid cannabis strains are by far the most popular category of cannabis seeds sold on the market today. They come in all different plant sizes, flowering times, yields, aroma, flavors, cannabinoid contents and effects. Read—High Yield Seeds List
- *Autoflowering Seeds: Grow plants that flower automatically (non-photoperiod). The seeds may be either feminized or regular. Autoflowering varieties are made with ruderalis genetics, resulting in seeds that will bloom under any amount of light—including 24 hours/day. Auto strains stay short and finish their life cycle fast, some at under 60 days from seed. They benefit from long light hours per day to produce a decent harvest weight. The plants can be spaced closely, as in SOG or SCROG cultivation methods. Autoflowering cannabis seeds are used often by indoor cash croppers, who cycle them indoors for perpetual harvests.

☺ Cannabis seeds are also categorized by their unique traits such as high THC strains, high CBD strains, high yield strains, landrace genetic strains, inbred line strains, award winning strains and more.
