Imagine a sleepy fireplace on a cold, rainy day, inviting you to sit and unwind in the slow warmth it offers – this is the kind of fire channeled by our Emerald Fire OG.

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.

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.

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!

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.

Collie Man Kush travels the rocky road, carries the heavy load, and definitely has the Sensi Herb. We were stoked to breed strains for Slightly Stoopid and composted a fuel and OG terpene orchestra just as frontman Miles Doughty likes it. Reported as “so loud it made my nose run and eyes water.” Or maybe you tear up because it’s so pretty, glistening with trichomes, sparkling like the waves off Ocean Beach, the band’s SoCal home turf. This high octane OG is perfect for watching waves… maybe even until 2am!

A 2018 Phenotype Mega-Hunt winner, this terpene forward selection stood out in a sea of 10k. The growth, bud structure, THC level, disease, pest, and mold resistance were all great, but the terpenes sealed the deal. Her terpene profile captivates you and brings you back wanting more. It’s a bit fuelly, a bit nutty, but mostly it’s rich with uncanny salty caramel and cream flavor. This feminized only strain is part of our new farm and gardener friendly line, easy to grow with wonderful long-lasting terpenes.

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.

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.
