Seedsman x Brothers Grimm - old-school power, modern performance.
Northern Lights 99 is what happens when Seedsman’s global reach meets Brothers Grimm’s breeding pedigree. This collaboration puts one of Brothers Grimm’s most iconic creations - Cinderella 99 - alongside a standout Northern LightsHaze selection from F2 Nevil’s NL5 x Haze stock, giving Seedsman growers access to something with real weight behind it. Not just a good name, not just another modern release - this is classic cannabis history reworked into a faster, more practical format for today’s home grower.
If you love old-school Haze but do not want to wait forever, Northern Lights 99 hits a sweet spot. It keeps the soaring energy, psychoactive punch, and unmistakable terpene depth that made Haze legendary, then sharpens it with the resin production, flavour, and grower appeal of Cinderella 99. Flowering in around 9 weeks and finishing outdoors by mid October in suitable climates, it offers the kind of heirloom-driven character that many newer strains simply cannot match. This is the appeal of classic lineage at its best - more identity, more story, more substance, and a result that feels built to last rather than built for short-term hype.
In the grow room, Northern Lights 99 stays compact enough to perform well indoors while still delivering excellent yields, long colas, and flowers so heavily coated in resin they can look silver from a distance. The flavour is where it really starts to separate itself: tropical fruit and candy sweetness up front, followed by diesel fuel, old-school Haze funk, and a savoury edge that gives it real depth. With THC potential of 25%+, high resin production, and an uplifting, potent, cerebral effect, Northern Lights 99 is made for growers chasing standout flavour, strong bag appeal, and the kind of high-energy experience that keeps classic genetics relevant.
Photoperiod strains rely on seasonal daylight changes, so harvest timing is closely tied to your local climate.
Photoperiod strains give indoor growers more control over size, shape, and when flowering begins.

In theory most strains can be grown outdoors, indoors or in a greenhouse but how well they perform depends on the more exact environmental conditions. This is most important outdoors where climatic conditions can vary widely, so please check the strain information carefully. If your climate is more extreme or growing season shorter you should choose strain that is specifically adapted. Indoor and greenhouse environments can be controlled and made suitable for most strains although space can be a factor for strain that grow very large.
Growing difficulty varies depending on a strain's resilience, structure and environmental needs. Some strains are more forgiving and better suited to beginners and a range of environmental conditions, while others may require closer control of factors such as light, humidity, temperature and feeding.
Our product information and that provided by suppliers can be an indication of potential levels under optimal conditions, and it should not be assumed that results can be replicated in all conditions.
Strains described as beginner-friendly, easy to grow or resilient, in particular Autoflowering Feminised strains, are generally more manageable for less experienced growers. These varieties are often a more reliable starting point than more specialised genetics.
