The Sativa Seedbank is a new seedbank founded in cooperation with Nirvana©. The breeders from Nirvana© developed new strains next to the already existing ones, exclusively sold by The Sativa Seedbank. The breeders gained a knowledge after 20 years of experimenting, crossing and stabilizing of cannabis seeds. Thats why the quality of the seeds is very high. The Sativa Seedbank is specialized in sativa strains, that means that we developed the seeds that will give a plant with the true sativa high.
