Cannabis sativa varieties generally are closer to the landrace varieties growing in tropical regions. They grow on the tall side, with long branches, providing a high yeild per plant. Sativa marijuana produces an energising 'head high', often with an inspiring, motivating and social effect.
The Sativa Seedbank range of sativa seeds only contains the best sativa strains by Nirvana. These plants have a slightly longer flowering period, but the results are well worth it. For an old school rushing high combined with modern yield quantities and genetics, you can't go wrong with these seeds.
