Take yourself off to a medieval cathedral. Claustrum is our sativa plant masterpiece: a cross between three strains of highly heterozygous families: Kali Mist, Super Silver Haze and Jack Herer. The first cross was between Super Silver Haze & Kali Mist, which has a highly unpredictable descendancy. Notwithstanding, a plant with 50% of the genes of its two ancestors was selected. This super-sativa-hybrid was crossed with Jack Herer, one of the best-ever varieties. As a result, Claustrum is a fusion between the world’s best sativas.

A plant that displays tremendously vigorous vegetative growth, which surprises even the most expert growers. It is advisable to optimise illumination as the plant is able to absorb 100,000 lumens per m2 (600W) indoors, where it can easily reach a height of one metre. Outside, if correctly fed , it can top 5m. Similar growth pattern to fir or candelabra with good internodal distance and perfect branch distribution, which enables optimum bud aeration. Almost unlimited supply of cuttings. Small number of leaves, but these are very large. Develops long, large stigmas or small hairs during flowering.


AROMA: Once smelt, it is difficult to forget Haze. It is a very complex blend of
incensed aromas that evoke the feeling of being in church. When smoked, the
smell multiplies noticeably, and it is at this point that you notice the cloister

TASTE: Like the strongest incense types that leaves a slightly pine/ eucalyptus
aftertaste on the palate. Without doubt one of the best tasting sativas.

EFFECT: Highly stimulating and euphoric. Recommended for leisure/
sociable use. When harvested at the right moment, it will yield maximum
THC and minimum CBD levels, resulting in a most psychadelic experience.
