Thunder Banana Auto This high-performance auto delivers solid THC levels of about 20% with heavy yields around 11-12 weeks after seed germination with 20 hours of daily light. As well as a long-lasting and powerful high, you can enjoy an unusually sweet terpene profile with a banana taste and hints of cloves. The genetics come from Alaskan Thunder Fuck （aka Matanuska） x Amherst Banana （Amherst Sour Diesel x Banana OG）. Yields are particularly heavy, and the dense frosty buds put some serious weight on the scales.
