Humboldt Seed Company’s California Sour Diesel is a slow, sluggish mix of Headband and Sour Diesel Bx3. Not even remotely racy, this strain is the opposite of a speed demon. Its gentle high accompanies a heavy physical buzz. Buds are light green like a sour lime, with a pungent potent aroma of fuel. Keep on moving when using this strain or prepare to be couchlocked.
