I was greatly disappointed with my GG#4 from DHN because I received a dud clone. GG#4 is known to shoot out dud branches, if those branches are used to make cutting, now you have dud clones circulating. Most people aren't aware of the GG#4's dud branch issue, and I'm not even sure if Dark Heart is, either. For your sake I hope they figured it out and you don't suffer the same fate I did.
I still trust and use Dark Heart Nursery clones. It's not like they passed off inferior genetics on purpose, it wasn't intentional, and like I said hopefully its been addressed.
Good luck.
