Green House Seeds
Green House Seeds is probably the most sold seedbank all over history. Their strains have been awarded worldwide. Genetics like Neville's Haze, White Widow, Great White Shark, El Niño, White Rhino or Himalayan Gold, have filled gardens of growers that smoked some in their coffeshop in Amsterdam.
Nowadays you can choose to buy 3 seed packs, 5 seed packs or 10 seed packs apart from their collectors edition mixes.
