High Strength Cannabis Seeds

The Cannabis seeds listed below have all been described by their respective breeders to have a THC concentration of AT LEAST 15%. These are the strains that may not produce heavily, but when it comes to comparing potency to yield, the pros outweigh the cons of going with the stronger stuff sometimes! We hope everyone gets the opportunity to enjoy at least ONE of these high strength strains. They truly are an experience! Just remember that these seeds are all intended for collector’s purposes only. Cultivation of the following beans is not condoned in countries where Cannabis cultivation is illegal. As always, no matter the motivation, PLEASE call or e-mail or Skype our customer service team. They are SO friendly! attrib_id=7&attrib_value=High : 15% +&in_stock=1
