Super Silver Haze: the most legendary Haze out there

Super Silver Haze is the ultimate sativa with legendary status. From all the spectacular Haze varieties out there, Super Silver Haze is the champion that stands victorious. Super Silver Haze became a big deal in the cannabis community during the latter half of the 90’s. It won the 1st prize during the High Times Cannabis Cup in 97’, 98’ and 99’. Three years in a row!

With its potent THC levels reaching the 19.11%, pace yourself if you’re a beginner. It hits you so fast, you will not know which way is up. It hits directly and lasts for a long time. Clear your schedule, you’re about to feel amazing for several hours.

This 70% sativa perfection derives from Skunk, Northern Lights and, of course, Haze. Imagine the perfect cerebral high of Skunk mixed with the Northern Lights' contemplative touch, combined with uplifting Haze genetics. Yes, that’s what Super Silver Haze is all about.

After 10-11 weeks of flowering, the trichome-covered buds will be ready for harvest. The yields are over the roof; 800g/m² can be expected from indoor operations. Outdoors, Super Silver Haze will develop buds, literally growing over the roof. With 1500g/plant and sky-scraping heights, Super Silver Haze develops monstrous amounts of weed under the bright sun. It might actually be one of the highest-yielding plants out there.
