Chemdog is yet another classic offering from the Green House Seed Co. It is a mouth-watering cross between OG Kush x Sour Diesel, making this strain a sativa/indica hybrid that offers a high THC level of 21.51%, and can give outstanding yields of up to 1,000 grams per plant. Chemdog is a strain that won 2nd place at the IC420 Growers Cup in 2008, and is good for SCRoG or LST. The effects of this are narcotic with a strong perception alteration, and is very long-lasting. Medically, this strain is ideal for pain relief, particularly chronic pain.
