How we make our selections
We curated this list of the best seed companies based on a combination of quality, transparency, and reputation. Here’s a breakdown of the criteria we used to evaluate and select each product.
Genetic quality
We looked for seed banks that had:
- Wide variety of stable genetics of common strains
- Rare or exclusive strains sourced from reputable breeders
- Good mix of feminized, autoflowering, and photoperiod seeds
- Accurate strain lineage
Growing information
Each website needed:
- Information on yield, flowering times, and growing periods
- Useful growing techniques to increase yield
Brand integrity
We wanted to see brands that had a:
- Germanation guarantee
- Positive reputation among amateur and professional growers
Customer experience
We prioritized brands that had:
- Reasonable price point for seeds
- Short shipping times
- Robust customer service network
Bonus points
We also considered if a brand had:

- Easy-to-navigate website
Types of cannabis seeds
In addition to thousands of strains, cannabis seeds break down into three main categories.
Photoperiod
- Require a change in light levels to enter the flowering stage
- Traditional choice
- Increased level of control compared to other types
- Potential for higher yields
- Better for experienced growers
Autoflower
- Enter the flowering stage after a set period of time, without a change in light level needed
- Less maintenance than other types of seeds
- Tend to be smaller than photoperiod seeds when grown, so better for growers with limited space
- Naturally resilient
- Historically have had lower yields and THC content than photoperiod strains, but modern genetics is closing the gap
Feminized
- Feminized seeds will only produce female, bud-producing plants
- No need to identify male plants for removal
- No risk of accidental pollination
- Not useful for breeders interested in producing their own crosses.
- More expensive, but feminized seeds have the potential for higher yields long term.
Things to consider when buying seeds
Keeping these factors in mind will help you choose the right seeds for your growing situation.
Desired effects and flavor
What do you want out of your seeds once they’re harvested?
- Indica, sativa, and hybrids can all have different effects and flavors, depending on the strain’s terpenes. Find one that has the effects you’re after
- Decide if your buds will be smoked or made into hash.
- Consider the projected THC and CBD content when making your purchase.
Growing conditions
The environment a seed is grown in can have big impacts on THC content and yields.
- Make sure the seeds you buy are well-suited to your growing location, whether you’re growing indoors, outdoors, or in a greenhouse
- Also, consider the amount of space you have in your growing area
- Keep in mind the soil quality you’ll be working with
Local climate
It is important to carefully consider your local climate.
- Some strains respond better to temperature fluctuations
- Areas with short summers will see better results with fast-flowering seeds when growing outdoors.
- If you live in a low-light part of the world, consider investing in a grow light
- Humid climates can encourage mold growth on plants. Make sure you plan with a resilient strain or grow in a humidity-controlled environment.
Quick facts
These definitions are here to help you navigate the seed-buying process and the language involved.
What is a strain?
A strain named variant of cannabis that has a distinctive look, aroma, and effect profile.
What is a terpene?
A terpene (aka terp) is an aromatic compound that gives cannabis strains their taste and smell. The most common terpenes in cannabis are Myrcene, Caryophyllene, Limonene, Pinene, Terpinolene, and Linalool.
What is a cross?
A cross is a strain that is descended from two different strains that have been crossbred together.
What is yield?
Yield refers to the amount of buds you can harvest from a fully mature cannabis plant. Usually measured by the dry weight of the harvested cannabis buds per square meter of growing space.
What is breeding?
Breeding is the process of combining cannabis genetics to create new genetics or to reinforce current traits. Some seed banks are breeders, others source their seeds from third-party breeders.
FAQ
Answers to some of the most common questions surrounding growing cannabis from seeds.
Is it legal to buy seeds?
Buying cannabis seeds is federally legal, but state regulations can differ. States can regulate both the availability of cannabis seeds in general, and even in legal states, there can be caps on the number of plants you can legally grow. Check your local laws before making any purchasing decisions.
How many seeds should I buy?
It depends on the space you have to grow, and the amount of cannabis buds you want after harvest. Five to ten seeds fit the needs of most home growers.
Can I sell the cannabis I grow?
Only if you have a valid state license.
Are autoflowering seeds better than photoperiod seeds?
It depends on the situation and what you want out of your plants. Broadly speaking, autoflowers are easier to grow and better for newer growers, while photoperiods are better for experienced growers since they allow the grower to have more control over the plant.
Can I buy seeds at a dispensary?
It depends. While some dispensaries may offer seeds, it can be inconsistent, thanks to differences in state laws that regulate dispensaries. Ordering online is usually the best way to buy seeds, where selection is better.
Are local or international seed banks better?
Both international and local US seed banks are good options. Local seed banks tend to have faster shipping times, but international banks can have a wider variety available thanks to more lax cannabis laws.
Can I smoke my cannabis buds right after harvesting?
No. Plants need to be dried, trimmed, and cured before they are ready to be smoked.
