The choice of variety depends on your personal preferences and growing conditions. Popular varieties include Gorilla Glue, White Widow, and Amnesia Haze. Each of these varieties has its own unique characteristics and requirements.
US cuttings are often genetically optimized and have specific characteristics that make them particularly robust and high quality. Classic hemp cuttings, on the other hand, come from more traditional breeding lines. Both have their own advantages depending on growing conditions and goals.
Hemp seedlings are young plants grown from seeds, while hemp cuttings are vegetative offshoots of mother plants. Seedlings go through a germination phase, while cuttings grow faster because they already have roots.
Automatic seeds, also known as autos or automatics, are seeds of plants that bloom regardless of the amount of light.
