This is the info i got from Sebring @Seamonkey84
^All of this^
Anyone that has currently received MW-CB seeds from me, has my F4 seeds. They are a lot more stable in structure than the F1* I received. Because MrGreenGenes inbred it for years, and then VerdantGreen ran it, which led to another F generation and finally to my hands, I can’t say exactly how inbred it is; For simplicity sake I’m using F1* so we remember that it’s way more inbred than I’ve made it. The seeds I’ll be giving out this winter will be F5 selections.
I still have a small number of seeds from F1, F2, F3 & F4 generations that exist incase I f*ck up and have to go backwards. There’s no sugar coating it, but sometimes a new F generation isn’t as good as it’s parents
