Brothers Grimm Seeds

Brothers Grimm Seeds was founded in 1996, when arrangements were made though Canadian seed reseller Heaven’s Stairway to distribute cannabis strains created by MrSoul and partner Sly. Known for selectively backcrossing, cubing and inbreeding some of the rarest of cannabis genetics on earth, Brothers Grimm became known for uncompromising quality & for producing genetic stability, high potency, short flowering times, heavy resin production, and intensely tropical terpenes. In 2002, the company abruptly closed due to security concerns. For many years after our seeds were no longer available, growers either jealously guarded their favorite clone mothers or shared them with their friends to keep them alive. Some breeders famously used our Cinderella & Apollo to create new hybrids as well as breeding filial generations as far out as F5.

MrSoul waited more than a decade to retrieve the precious clones and seeds he’d stashed safely away. In 2015, he met Duke Diamond and together they developed a concrete plan to resurrect Brothers Grimm in Colorado. The combination of these two breeders’ abilities, along with a deep reservoir of unique cannabis cultivars, is the foundation of our company.

Breeding Philosophy

Brothers Grimm are famous for creating high THC strains that produce consistently outstanding results. The creation of Cinderella 99, through a multi-generation breeding program, distinguished us long ago as breeders who take the time to do things right.

After a dozen years on the sidelines, we can’t help but observe that today’s seed market is flooded with poly-hybrid crosses, seemingly created with no logical, deliberate goal or breeding plan. Such seeds produce plants of many different phenotypes – like lottery numbers.

By contrast, Brothers Grimm only cross a male and female after having thought of all the reasons WHY we want to do so. We design our seed lines to produce consistent plants that all share the qualities we selected for in the breeding program that created it.

We are able to take this approach because our breeding stock is a rare collection of landrace and other stable cultivars, each representing unique genetics. Using this gene pool, we painstakingly choose and combine males and females in a deliberate program to create hybrid seeds which produce plants consistently displaying the desired characteristics. There’s very little variation; our clients don’t have to hunt through several different phenotypes hoping to find a good one.

So which characteristics do we select for, when breeding our hybrids? The goal in each breeding program will vary somewhat of course, but the general list of traits we are known for include:

  • Compact overall plant structure
  • Dense budding
  • Fast-flowering
  • No hermaphroditism 
  • High resin production
  • Intense psychoactivity
  • Unique palette of terpenes 
  • Optimal yield

  4. Brother Grimm – Apollo XX Marijuana Seeds

    Brothers Grimm Seeds
    Apollo XX

    Brothers Grimm have traditionally refused to offer feminized seeds because we didn’t believe it was necessary, and we didn’t want to risk hermaphrodism. However, our research during 2016 lead us to a method which produced our first feminized version of Apollo Eleven – we call it Apollo XX, to indicate the two X-chromosomes.

    Starting at: $85.10

  5. Brother Grimm – Cinderella 99 Marijuana Seeds

    Brothers Grimm Seeds
    Cinderella 99

    She’s BACK… the legendary Cinderella 99. When Brothers Grimm closed in 2002, the small batches of our original seeds were quickly depleted. Over the years, elite growers continued to clone their Cinderella 99 moms to preserve them, and several notable breeders continued the legacy by creating hybrids of C99.

    Starting at: $157.67

    Cindrella XX

    Over the past two decades, Cinderella 99 has become legendary as the “Holy Grail” of indoor marijuana.

  8. Brother Grimm – Durban x C99 Marijuana Seeds

    Brothers Grimm Seeds
    Durban x C99

    We inherited this elite female Durban clone from a group of underground growers last year and proceeded to flower a bunch of them for research. We were blown away by the aromas given off by the flowers – pure black licorice. Also impressive was the plant’s sturdy structure and minimal stretch during flowering – clearly not a Sativa-dominant morphology.

The lineage of this hybrid is impressive indeed. We crossed a Durban-Thai female grown from original S.S.S.C. seed stock to our favorite Cinderella 99 female by STS-inducing the C99 to create 100% female pollen.

  10. Brother Grimm – G13 Genius Marijuana Seeds

    Brothers Grimm Seeds
    G13 Genius

    We crossed two famous clone-only females to create a 100% female Super-strain. The seed mother of this hybrid is Neville’s G13/Hashplant from The Seed Bank, circa 1990. The pollen came from Silver-Thiosulfate reversal of MrSoul’s Genius. The outstanding Airborne G13/HP clone has a flavor profile of lemon/lime with a sour milk undertone... which makes her a perfect complement to MrSoul’s Genius female (mother of the Apollo line) so we decided to combine them and thus create a 100% female strain with INCREDIBLE lemon/lime and sweet/sour flavors and aromas.

    Starting at: $85.10

I called him and thanked him for passionately continuing my genetics over the years while I was MIA and told him I’d create this strain, Green Avenger in his honor.

  20. Brother Grimm – Rosetta Stone Marijuana Seeds

    Brothers Grimm Seeds
    Rosetta Stone

    We received so much popular demand to re-issue Rosetta Stone that it was decided to go one better. MrSoul had wanted this release to be even heavier in resin production and overall yield without sacrificing flavor. So this Rosetta Stone flowers a bit longer, but what a joy it is to behold these sparkling colas finishing their 8th and final week. It clones remarkably well and is generally an easy plant to work with.
