Humboldt Seed Organization: 21 Californian Cannabis Strains

Humboldt Seed Organization sits in Humboldt County, the top corner of the Emerald Triangle in Northern California, and that's where most of their breeding stock comes from. They work with organic nutrients and lean on local cuttings rather than chasing whatever's trending. Chocolate Mint OG 2.0 is a good example: the 90s Emerald OG cutting crossed with Granddaddy Purple, a Northern Californian classic. Dedoverde Haze goes the other way, California Haze crossed with Amnesia, and it came out at 18-24% THC.

Bred In The Emerald Triangle, Grown In Your Spare Room

Cali genetics don't always behave in a European tent, so it's worth knowing which ones stretch. Blueberry Headband turns into a room-dominating plant and can hit 3m outdoors, ready around October. If your grow space is small, that's the one to skip. OG Kush Auto has long internodal spacing and pushes to around the 1.2 metre mark, so stake her early. Both are still forgiving: Blueberry Headband is tough enough that a first-timer can mess up a feed and get away with it.

Feminized Photoperiod Or Autoflowering: Pick Your Half Of The Shelf

The photoperiods are the yield play. Green Crack 2.0 (Skunk #1 x pure Afghani, 40% indica / 60% sativa, 18% THC) finishes indoors in 60-65 days at around 500 g/m², and outdoor plants come in early October at 800-1200 grams each. The autos are the speed play. Chem-Bomb Auto (Chemdawg 91 x Bubba Kush Auto) starts flowering after 30 days and wraps the whole cycle in about 70, growing bushy with heavy side branching, so main-lining and low-stress training pay off. OG Kush Auto takes 10-11 weeks. Newer names like Banana Sapphire and Lemon Citron sit alongside them, and the full cannabis seeds range has more autos if none of these fit.

From Petrol And Pine To Chocolate Mint

Flavour is where HSO shows off. OG Kush Auto opens with pine and petrol, with citrus and pepper sitting underneath. Pineapple Skunk goes sweet and fragrant, then hits you with a pineapple aftershock. Watch out for that smell, though: Pineapple Skunk penetrates everything around it, and keeping a plant discreet is genuinely hard work. If odour is your main worry, Chem-Bomb Auto's earthy terpene profile is far easier to live with in a flat.

Humboldt Seed Organization Or Humboldt Seed Company?

Two different breeders, two names that look almost identical, and we get asked this constantly. This page is Humboldt Seed Organization (HSO). Humboldt Seed Company has its own separate shelf on our site, so if you searched for one and landed on the other, check which logo is on the pack before you order. Both come out of the same part of California, which is exactly why the confusion happens.

Practical tip: if you're running Pineapple Chem Auto or OG Kush Auto, put the stakes in during week two instead of waiting for the stretch. Autos don't give you a recovery window, and a leaning plant at week five costs you cola weight you never get back.
