Sorry for the delay. I had to go back to and look up where I got those GSC seeds. 
The GSC were made by Blimburn. I got them as freebies on a Seedsman order. It’s a straight pollen chuck. I had one of those GSC females, and I hit her, a White Widow, and a Strawberry Diesel x C99 with MMH pollen.
The original breeder on MMH was Darthcultivar, and my understanding is that he was looking for a fast finishing “Haze”. From what I’ve been able to gather, he used an Afghan dom female, and a fast Mango Haze male. I’d say he hit it. The straight MMH will finish in 9-11 weeks.
Here’s a link to the log from the seed run: Seed Run Co-Op: Maui Mango Haze (CLOSED) There are pictures from the seed run, and also from the bud run I did after that. Both runs and some odd mutations, and you can see them in the thread. They also had some interesting branching characteristics. On some nodes, there were 4-5 branches.
As far as the GSC cross, I’ve never grown that one out myself, but my buddy @Limeflavouredheadbut has grown it, so hopefully, he’ll toss in a couple of cents worth. I will say this. He said that for about the last 6 months or so, the GSC chuck had been he and his wife’s favorite strain.
I think they’ll just keep going. I put some MMH clones outside on 5/27, and we were getting 14 hours, 18 minutes of daylight. By the end of June, they were already flowering. We don’t get 15 hours of daylight here. On the solstice, we get about 14 1/2 hours, so I think they start flowering right around that time.
So, I’ve got a shitload of straight MMH seeds. If any of you guys are interested, I can probably get some to Fatty, and he can distro them like he did with these. I’ve also got a bunch of the Widow, and SDxC99 chucks.
This makes the 3rd continent that those chucks have made it to. I must say, it’s very cool to see. Thanks for running them!
