G13 Haze by Mr. Nice Seedbank – a legend in stable seed form
This strain is not for beginners – but it is a real highlight for connoisseurs. G13 Haze combines the legendary G13 with Haze genetics and was bred as an IBL (Inbred Line) because the original G13 only existed as a clone. This allowed Mr Nice to create a stabilised version that preserves the essence of this potent mother plant.

More info
As you would expect, the effect is intense, clear and long-lasting. Medically, G13 Haze is valued above all for its analgesic properties. The strain is not only a flavour heavyweight, but also genetically, and is ideal for breeding potent hybrids. However, it requires gardening finesse, as the phenotypes want to feed differently – especially sativa-dominant varieties need a gentle hand when it comes to EC levels.
