Revolution (Harlequin x Otto #1) is another mostly sativa F2 hybrid from Rich Kehrer. The revolution in the Cannabis world is CBD strains right now, and this one is not like your normal CBD strain of small plants and low yield. She is a big girl with plant heights reaching 10 ft and more and with extra large colas, this strain can yield very well. A high Sativa Dominate strain that can produce High CBD and less then 1% THC plants that. Being an F2, there will be different Pheno's and even a chance of High THC plants, but don't let that stop you from trying this strain as the Revolution is here and you don't want to say you missed this strain. This is very good medicine for pain relief, gastrointestinal issues, AIDS, stress, and ADD. Also good for PTSD.
