Sour Lemon is a forth generation medical cross, bred using a fine looking Ultra Lemon Haze auto and N.W’s SourD male. Sour Lemon, light green in colour with flecks of bright orange pistils and a heavy coating of resin, initially brings a sweet and sour lemon flavour with a slight bitter edge reminding of the hard candies, lemon sherbets or a batch of cloudy lemonade.
