Jordan of the Islands Chemo is a short squat dark green marijuana plant. This legendary cannabis strain doesn’t have much of a stink, which is great for people who have problems hiding marijuana smells. Chemo is a powerful pain reliever, couch-locking, sedate, basically it is one of the strongest marijuana strains available. Our marijuana seeds are moderately to above average yielding and have the fastest flowering time. Chemo finishes flowering in 45 - 55 days. Another advantage for medicinal marijuana growers.
