An old-school strain from the ’70s, Willy’s Wonder (aka William’s Wonder) comes from breeder SickMeds Seeds who claims to have created it from a blend of original Super Sativa Seed Club Afghani seeds. The resulting plant has 20% or higher THC with a sweet citrus taste and aroma, according to the breeder. Others have reported THC levels in the 30% range. SickMeds Seeds says Willy’s Wonder is a 100% indica plant that grows short and wide. It can only be grown indoors and takes eight to nine weeks to fully flower. Willy’s Wonder is known as a heavy producer at harvest time. The strain delivers an uplifting sensation along with deep physical relaxation that’s likely not the best choice for beginners.
