if you pay a bit of attention to whats been going on with him, you'll realize that DJ set up his son (JD) to get a start in the business and his son's work is released under the "Second generation genetics" brand.
DJ's work has always been under the "Old World Genetics" brand.
It seemed DJ had become disillusioned by his experience having all his best work ripped off by european breeders who invited him over to partner with them . . . twice.
Most of the legendary rep for blueberry from the glory days went to those companies that lied to him and stole his gear then kicked him out.
DJ did a few collabs afterwards with Legends Seeds and Chimera, but mostly, he kept a low profile for a while until JD expressed an interest in the game.
JD's work seems to be hybrids of "Dad's" stuff with other people's cuts.
I got the same negative impression from JD.
Don't know him so can't say what the real story is, but the kid should let someone else run his social media cuz he talks about stuff he has no idea about.
Once JD got his feet under him, DJ seems to be re-invigorated and returned to active breeding with a passion.
DJ has always been an active member of the community, even during this quiet period, and shares knowledge and his keeper genetics with anyone he meets. Seems you need to get face to face with him to experience that though, so if that's not you, then you look at the very high price of his seeds packs that for the last 10+ years have produced a high percentage of mutants and low potency plants.
I know one of DJ's friends/testers and he has been reporting that DJ's new gear (Newberry and Happy Pussy) are a return to the glory days of DJ's lines, maybe the best work ever.
He also has other lines under development that have potential to make his work a serious contender again in today's very competitive market.
If the OP got a pack of Newberry, I suspect he is going to be very glad he did. They sold out fast at all seedbanks, and IG pics starting to show up look great.
Again, Newberry and happy Pussy are all DJ, not his son's work, and by insider reports I've heard, those seeds hold the fire.
