Humboldt Seed Company

Cannabis

Two all-time A-list strains create an explosion of fuel terpenes. When we met Greg – the creator of Chem Dog – We felt like we were in the presence of royalty. We thanked him for his contribution to the species and shoveled our own seeds into his lap, hoping to begin repaying the debt that cannabis enthusiasts owe him. The name pays homage to the environmentalists protecting the giant redwoods of Humboldt. We were on the front lines in 1996 and beyond for the “Redwood Summer” blockades!

As a loving and protective father, our founder Nat Pennington is raising two strong women in the special community that is Humboldt County. Nat says when young women are raised to respect nature and take care of the people around them that they grow up strong and beautiful, especially when they help to farm the ganja. The Farmer’s Daughter strain is an homage to the young women who will hopefully carry the cannabis community into the future, fostering justice and equity. The strain’s potent THC flowers are not to be messed with but will yield unrivaled beauty when given the proper care and respect. Strong branching and growth doesn’t require overbearing support but will respond well to guidance from a knowledgeable hand who knows when to “just let the plant grow”. This is one of our new genetics that’s intended to help small farmers survive the tough times we’re seeing in the “free market”. With genetics like this we hope that a family farm can survive another season so farmers can grow with their daughters.

Originally crossed in 2017 by Ronnie of 8-Mile Family Farms in Eastern Humboldt, Zkittles and Blueberry Muffin were destined to meet and create a mind-blowing fruit cocktail of terpenes. We knew this was worth perfecting, and three years later, after honing her sugary blossoming terpenes to match Hibiscus, she is finished. Vigor and mold resistance were noted traits that were easy to select for while maintaining optimal terps and appearance. Be prepared for a great crop of in-demand Hi-biscus!

An exciting new strain that will not disappoint. With high THC levels complemented by juicy terpenes gushing with lemon flavor, the Lemongrass name came easy. Production leaves nothing to be desired: the plants are huge and display hybrid vigor. Disease, mildew and mold resistance is high and flower structure is perfect for machine or hand trimming. A solid choice for California farms looking for a foolproof way to hit the season running. Don’t hesitate, seed supply is limited and after you grow out the Lemongrass you will surely want to thai one on!

A purple train wreck phenotype unlocked when we crossed Train Wreck with the original Blueberry Muffin. We knew it was a“unicorn” from the beginning. An excessively wide growth pattern will fill your garden past the point of reason, but not to worry—she is extremely resistant to Powdery mildew and bud rot. Its signature turpentine smell comes in part from high levels of Terpinolene.

From our product tester Willy G comes a strain with a very high CBD to THC ratio. These seeds should all produce flower with an over 20:1 ratio of CBD. Willy G and his cousin procured these seeds from Bakka Valley in Lebanon and we bred and pheno hunted them to find this wonderful silk-road masterpiece. These seeds are incredibly unique and Willy G is a wonderful person who uses cannabis to help with the effects of his cerebral palsy. Please credit Willy with any crosses you make of other uses of this strain – he deserves it!

Supafreak is the product of an extensive breeding and selection process conducted recently by Shapeshifter. It was selected from 120 phenotypes of F6 generation Freakshow, and is completely stable for the following new traits: early finishing, it’s done Sept. 10-15 outdoors at most latitudes. A quicker finish indoors, 7-8wk. It has a lacier, thinner leaf structure, especially toward maturity. Impressive bud structure with astounding calyx ratio. The terpenes are unique and hard to describe, unlike anything we’ve smelled or tasted before. Blends of floral, fruit, chem, spice, and skunk. Nice fat colas can be expected, and also, like all the Freakshow lines she’s amazingly pest and mildew resistant.

We threw around the name Humboldt Smoothie before deciding that banana and mango are the dominant aromas. The combo of terpene profiles that make these unique seeds is rare in our experience. This strain packs a punch and might leave you on a tropical beach soaking up the sun. You will appreciate the huge plants and amazing vigor. PM resistant but can have mold towards the end of the season. THC hovers around 22% with high trichome production, but the nose is what makes this so special.

The Phenotype Mega Hunt winner that can be credited for this strain had chunky resin dripping buds and glistening trichomes, like a fresh iced slice of pound cake. We were hesitant to breed with Wedding Cake due to experiences with herms, but we crossed her with Notorious THC and found a phenotype that didn’t have that issue. While we had great experiences in our full-term R&D, do keep your eyes out, better safe than sorry! Humboldt Pound Cake’s buds are as aromatically striking as they are visually enticing. With rich earthly flavors and tangy almost sour notes, this line has a satisfying terpene profile and a quick high with uplifting and euphoric effects.

Mango & Sherbert must have been destined to meet at the HSC breeding facility in Eastern Humboldt. Our breeding coordinator is one of the best at pairing strains and we knew that the Mango Trees could work her magic while honoring the Sherbert’s smooth flavor and mellow sweetness. Expect much larger plants than the Sherbert cut covered in the fuzzy trichomes you are used to from the strain. Light green buds with orange hairs smelling like mango and sherbert with a hint of whip cream and strawberry on top. Effects are relaxing, making it a great afternoon strain.
