Best Cannabis Seed Banks

By Last updated on July 16, 2021Last updated on July 16, 2021No Comments

Growing your own cannabis plants is both enjoyable and rewarding. Sure, it is not an easy task to complete, but if done successfully you can be left with lots of organic homegrown dank. There are many ways to grow weed and many decisions to be had. First and foremost is deciding whether you would like to start your grow from seeds or clones.

Growing from seeds is perhaps the most traditional method and experienced growers like them because they have the ability to be cross-bred into new and unique hybrid strains.

You may have found a seed or two in your weed stash and have been tempted to plant it. However, this is not the best way to go. Investing in quality cannabis seeds from the start can potentially save you money and stress in the long-run.

When you buy seeds from a respected seed bank, you are paying for guaranteed quality. Established seed banks have teams of dedicated breeders and growers constantly working to improve their genetics. That means, after germinating your seeds, you can rest assured that your plants will grow strong and healthy and should reward you with good yields of top-shelf bud

However, understanding the cannabis seed market can be challenging because cannabis is federally illegal and therefore the amount of regulation on seed banks is limited.

Is it legal to buy cannabis seeds?

Cannabis 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 cannot cross state lines.

This makes it hard if not impossible for a seed bank to run in the U.S. the way they do in the U.K., the Netherlands, Spain, or Canada. Seed banks can sell their seeds 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.

Seed banks understand this and go through any means to make sure that their seeds get through customs inspections.

Cannabis seeds by genetics

Cannabis seeds by genetics

Seeds carry genetic information from two parent plants and can express many different combinations of traits: some from the mother, some from the father, and some traits from both.

Cannabis can be either male or female (also called “dioecious”) but only females produce the buds we all know and love. For reproduction, males have pollen sacs and pollinate females, causing female flowers to produce seeds.

The types of seeds available for purchase include:

  • Regular seeds: If you buy a packet of regular seeds, they will come with a mix of males and females. A lot of cultivators prefer to grow these because they have not been backcrossed (inbred) as much as feminized or autoflower seeds. You will need to sex out the seeds once their reproductive organs show during the flowering phase and afterward discard the males because they do not produce buds and will pollinate females, resulting in seeded flowers.
  • Feminized seeds: Only female cannabis plants produce the cannabinoid-rich flowers that deliver the flavors and psychoactive effects consumers look for. The feminization process for seeds is accomplished by essentially breeding two female-dominant plants together. This is possible because weed plants are not always strictly male or female, each plant has the ability to produce flowers of either sex under the right conditions. So, to eliminate the male chromosomes, breeders take a female plant and put it under stress by interrupting its light cycle or using other techniques until it produces male flowers, which they use to fertilize another female plant. After a few rounds of this, the male part of the plant will essentially be gone, and all plants grown from these seeds will be female.
  • Autoflower seeds: 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 7-12 weeks from when you put the seeds in the ground. The downside is that they are less potent and yield smaller amounts, but autoflower seeds are great for people who want to grow cannabis but do not want to spend a lot of time doing it.

Cannabis seeds by strain

  • Sativa seeds: They produce thin and tall plants and take a longer time to attain maturity. Their yield is more than the indica-seeds plants, but the THC percentage is quite low. The sativa strain is highly energetic and produces stimulating effects.
  • Indica seeds: These produce short, bushy plants that take less time to mature and have higher THC content than Sativa kinds. The yields from indica species are smaller but offer relaxing and soothing properties.
  • Hybrid seeds: A hybrid is a result of combining both indica and sativa cannabis strains. Pro growers consider hybrid seeds as top performers as they hold both of the species’ best traits in a single growth.
