I believe the brown moruga is already a cross: 7 Pot Brown x TSMB. Last year I crossed the BM into a Primo and am growing the F1 seeds this year... keeping my fingers crossed that it really is a cross, otherwise I will have some more Primo plants.
I ordered some fresh pods from Judy a couple of years ago. I grew the seeds out . They were bumpy pods and had tails. They were extremely hot!!!! I am growing some out this year. Here is a link to one I grew last year. http://thehotpepper.com/topic/58315-the-ames-glog-2016/#entry1273564
I did give some seeds away for others to grow out. I do have some seeds left if anybody wants some.
