Scarlett Johansson move over, there’s a new species in town. Blue Widow is a fan favorite, with sweet strong fruity smells and colorful buds. Also known as Blue Venom, Berry White, and White Berry, Blue Widow is a cross between White Widow and Blueberry. Users love this strain for its effects which are simultaneously inspiring and relaxing. Unlike other indica-leaning Widows, this plant grows taller than average and hits the brain with heady stimulation. Heavier doses may have sedation effects, effective for insomnia.
