Why This
Collaboration Exists
There's no shortage of new strains. But there's a difference between something new, and something that lasts.
Seedsman has always focused on access — making a diverse range of genetics available to cultivators and collectors across the world. Brothers Grimm Seeds built their reputation on the other side of that equation: creating cultivars that growers still talk about years later.
This collaboration connects those two ideas. It makes proven breeding work more accessible, without diluting what made it so valuable in the first place.
Not Every New Release Needs a Fanfare
Some strains speak for themselves. Northern Lights 99 is the result of bringing together genetics that mean something, from people who've spent decades perfecting them.
A meeting point between legacy and accessibility.
The Genetics
LineageNorthern Lights Haze
Built from a specifically selected Haze phenotype found within the F2 generation of Nevil's NL5 × Haze. It brings the energy, structure, and terpene complexity that made Haze genetics so influential.
Cinderella 99
Where the profile really sharpens — adding sweetness, resin production, and a level of consistency that defines the final expression. One of Brothers Grimm's most iconic creations.
Northern
Lights 99
A hybrid that leans into clarity and energy. Uplifting, cerebral, suited to daytime use — something that carries momentum rather than slowing things down.
Grow Perspective
CultivationNorthern Lights 99 offers a practical route into Haze-led character without the usual trade-offs. It retains the personality of classic Haze genetics, but in a format that fits more comfortably into modern grow cycles.
A Different Kind of Release
Not chasing the next name — returning to something more considered, where the breeder matters, the lineage is clear, and the result speaks for itself.
- Rooted in real breeding heritage, not short-term trends
- Direct connection to Cinderella 99 — one of cannabis's most enduring cultivars
- More accessible take on Haze without sacrificing the character that makes it worth growing
- Layered terpene profile — tropical, sweet, diesel, funk, haze. It evolves.
- High-energy, daytime effect profile with clear cerebral appeal
- Visual quality — dense, resin-rich buds with a bright silvered finish
