Cross pollination can definitely cause "super breeds" to occur. When I was a young lad I experienced a habanero that was far hotter than it should have been. In fact I'm pretty sure it was hotter than these ghost peppers were. It could just seem that way because I was not used to hot peppers at the time..
I'm working on an indoor greenhouse. I'm going to check out some LED lights. I just found out that they are much cheaper than they were years ago, and apparently they are awesome for indoor growing :)
Thank you for your thoughtful comment Jerry :)
