Amethyst OG is a 80 Indica/ 20 Sativa marijuana hybrid. The kush was created by Soma Seeds. The buds looks like sparkling purple gemstone with its small, rock hard buds, covered with crystals. Don't let the Amethysts' appearances deceive you, as these small buds are packed with THC and are quite potent. With THC levels up to 22%, beginners should be mindful of the dose to avoid extreme lethargy. Amethyst marijuana is good for evening time use due to deep sedative effect.
