This main strain is "original kush" - one of the plants is a clone from another grow which is "Blueberry/Purple Kush". I've grown Original Kush for a while now - I needed a new mother plant and had the seeds - so thats been the purpose of this grow.. the clone was added because I only had 5 seeds . Its been a success as far as taking a mother - soon we'll see which plant puts on the most weight.
