A top-of-the-line backcross (Jamaica x Jamaica/NL5/Haze), between a Dutch NL-5 champion, a pure Haze and an extraordinary, very stable Jamaica Lambsbread stud from the Blue Mountains of Jamaica, with which we have achieved an incredible sativa climax and a great yield, while it has become better adapted to indoor cultivation. It stands out for its great resistance to diseases and mould in humid climates. Time seems to stand still and the senses are sharpened. It is by far a gem of the sativa classes that professional breeders will want to have in their collection. The long flowering period is more than compensated for. Gradually shorten the light cycle from 12 to 8 hours in the last 2 weeks to fix and increase the resin, thus avoiding re-flowering. Minimum vegetative period of 30 days for a high yield.
