All Levels Of Hotness Are Not The Same?

I was talking to a buddy who is also growing some Ghost Peppers and decided it was time for an update. He's already moved his inside, but I'm still rockin' it outside for now. We've both got some good peppers growing with one ripe. Someone told me our peppers might not be as hot as the "original" Ghost Peppers as the growing conditions are skewed, so I guess we'll find out soon enough. Stand by two new hot sauce varieties featuring said pepper-and if it is not hot I'll be disappointed . . . I am guessing another 3 weeks maybe?
