Soma Seeds Amethyst Bud is a mix of Lavender Bud and Afghani Hawaiian so the dark purple colour from the purple Kush part of it’s genetics comes through and looks amazing. . Amethyst Bud is 80% indica and 20% sativa. This bud may be on the smaller side of plants, but they are quite dense with many THC crystals visible with the naked eye. The smell is strong and pungent with a good high for relaxing with a good friend. When it looks like it’s ready, wait a week. It normally takes cannabis seeds 9-10 weeks to flower.
