Arjan Roskam. The founder of Green House Seeds is one of the most prolific personalities in the world of marijuana. He has been dubbed as “The King of Cannabis” thanks to the many strains that his company has developed. One of which is part of his signature strains collection, Arjan’s Ultra Haze #1.

This Sativa-dominant hybrid is a three-way cross between Neville’s Haze and two landraces from South East Asia – Laos and Cambodia. Together, these three produced a multi awarded Sativa that has earned good reputation amongst cannabis connoisseurs.

But, like many other Sativa strains, Arjan’s Ultra Haze #1 is slow to flower. It typically takes more than ten weeks for users to get a glimpse of its minty forest green buds. However, the one-of-a-kind Sativa effects, delightful flavors, and most especially the massive yields all but make up for the long time.
