Well its new to me anyway. I havent been able to find anything anywhere about this cross online but maybe some of you have heard of it. Grandaddy Purple crossed with Chemdog. Should be an amazing combo. Guy said the stuff sells for $600-700 oZ in LA Stated it yielded pretty well too 1.5 to 1.75 lbs per light in SOG with CO2. We will see. I hope it can get a decent yield atleast. I grew GD Purple before and it was a low low yielder but Chemdog should up the yield quite a bit I would think. I love trying new strains.
