Protecting Cannabis Kultivars & Understanding The Truth About Seeds

For many of us growers, cannabis kultivation is more than just a hobby—it’s a labor of love, a way to express creativity and connect with the natural world. But for those who’ve poured time and care into developing their own unique strains, the question of protection becomes a personal one. How do you safeguard something you’ve created without the money for patents or trademarks? And, at the heart of it all, can anyone truly claim to “OWN” a seed?

Here’s what every grower should know, both about protecting their work and respecting the natural heritage of seeds.


Protecting What You’ve Created

If you’ve worked hard to create a new cultivar, you don’t need a fortune or a legal team to defend your work. Here’s how you can take steps to keep it safe:

1. Document Everything

Keep a clear record of your work. Write down every step of the process—what you crossed, when you planted, and the traits you observed. Take photos or videos as your plants grow and save those files with timestamps.

Why? If someone tries to claim your strain as their own, this documentation proves you were there first. Think of it as your personal fingerprint on your creation.

2. Share Publicly

It might seem counterintuitive, but sharing your strain with the world can actually protect it. By posting photos, descriptions, and lineage details on forums, social media, or grower websites, you create a public record that says, “This is mine, and I made it.”

This step makes it much harder for someone else to swoop in and claim credit. Once your work is out there, it’s tied to you.

3. Use Open-Source Principles

If you’re passionate about keeping cannabis genetics accessible, you can choose to release your strain under informal terms, like “free to grow, but not for resale or patenting.” Adding this to seed packs, social media posts, or community discussions helps set boundaries, even if it’s not legally binding.

The goal here is simple: to share what you’ve made while ensuring people respect your work.

4. Build a Reputation

In the cannabis world, reputation is everything. If you’re known as someone who’s passionate, skilled, and ethical, people will recognize your work and respect it. Engage with your local grower community or online groups. Share your knowledge, and your name will naturally carry weight.

Even if someone tries to claim your strain, a strong reputation can act as your best defense.

5. Partner Wisely

If you do want to collaborate with others, make sure you trust them. Simple agreements—like non-disclosure agreements (NDAs)—can help clarify what’s expected and protect your work.


Why Seeds Can’t Truly Be Owned

Seeds Were Here Before Us

Cannabis, like every plant, existed long before humans. Seeds are part of the Earth’s natural legacy—a gift that’s evolved over millions of years. Even when we breed plants into new forms, we’re still working with something we didn’t create.

The idea of owning a seed, or patenting a genetic trait, is controversial for a reason. It can feel like claiming ownership of the air or the rain—things that belong to everyone.

Ethical Challenges

Companies such as Monsanto now owned by Bayer, and Scotts Miracle-Gro (through its subsidiary Hawthorne Gardening) have aggressively pursued intellectual property rights over genetic traits, particularly in agriculture. In cannabis, organizations like Biotech Institute LLC have patented a range of cannabis strains, creating concern among growers.

Biotech Institute’s patents, which cover specific cannabinoid and terpene profiles, sparked debate about whether such patents stifle innovation and unfairly claim ownership over shared genetics. Smaller breeders and growers worry about lawsuits or being pushed out of the market entirely.

These practices often overlook the work of traditional cultivators, Indigenous peoples, and small growers who’ve shaped cannabis genetics for centuries.


Practical Advice for Growers Without Patents

If money isn’t an option, focus on what you can control:

  • Document and share your work to establish yourself as the creator.
  • Connect with your community to build trust and protect your reputation.
  • Set clear boundaries about how your strain can be used when sharing seeds or clones.

By taking these steps, you’re not just protecting your work—you’re contributing to a culture where cannabis genetics are shared, celebrated, and respected.


The Bigger Picture

At the end of the day, seeds are part of something larger than any one of us. They’re nature’s creation, and we’re lucky to work with them. As growers, we shape, nurture, and guide plants, but we don’t truly “own” them. Instead, we’re stewards of a heritage that connects us to the past, present and future.

Corporations may try to patent specific traits, but the heart of cannabis breeding lies in the hands of passionate growers like you, who respect the plant and its origins. By staying informed and connected, you can protect what you’ve created and help ensure that cannabis genetics remain accessible to all. —#ThoughtBotApproved

Captain Technical here.

Nice writeup! I’d just like to say that there aren’t really any cannabis cultivars, only the more broad category of cultigens, because the former involves registration with the ICRA. Instead, we have trade designations

What do ya think @resimax should it be changed?.. or let it ride since we all usually say cultivar or strain? I like how you pointed that out quick!

It’s a pet peeve of mine. Cultivars and trade designations can be legally protected. Patented in the former, trademarked in the latter. It is still possible to patent a trade designation, though not the name, only the product. Trademarks and patents are a can of worms I’d not rather get into.

I’d just call it a strain. A “strain” covers all cannabis that is a descendant of some known variety.

Landraces are kind of weird there, though. Some are neither strains nor cultigens (some landraces are cultivated, because the definition of landrace is fairly loose). A cultigen is any plant that was produced through cultivation, not grown naturally. And a strain requires the parents to be known. To make matters even more confusing, it’s arguable that there aren’t even any landraces left, due to cross-pollination, depending on your definition of the word. They could be heirlooms or something else.

This is giving me a headache just writing about it, so sorry for the aneurysms people.

Thanks whenever I start breeding this will be helpful.

For documentation, it’s a fantastic idea to press your plants at each filial generation to demonstrate the changes you worked towards.

Here is a wonderful video on how to do just that:

If trouble were to arise in the future, say someone trying to sue you or claim your work is theirs; DNA samples can be taken of your herbarium and the “truth will be in the pudding,” as the say.

I imagine the kind of person who would steal your work is the same kind of person who would change the name and remove you from the narrative entirely.

Funny you mention that. I have a friend who developed a strain everyone has heard of. He never tried to capitalize on it. Shared it with many ‘professionals’ who blatantly messed with it, changed the name, or just generally made some kind of unfriendly move.

You can’t save it is the real answer. How many copies of cookies do you think are out there? What is Bernie gonna do?
