Ultra Sour by THSeeds is a tart cross out of Amsterdam. This strain is the product of crossing MK Ultra and East Coast Sour Diesel, creating a sativa-dominant bud that smells of pine and diesel and are deep green with rusty orange pistils. The potent strain can be a little daunting for inexperienced consumers, so start low and go slow.
