if you check out drgreenthumb.com he has some kush's. he seeded the clone then grew out lots of plants until he found a true male then he used that for the seeds.if you email him he would explain it better. someone on another forum said that these are exactly like the clones and well worth the money considering a clone of a kush strain is way more. i ordered the matanuska thunderfuck and and am growing them right now(9 seeds germinated and it was a 6 day delivery when i ordered by phone) if these are good ill be ordering the bubba kush. hope some of this helps you.
