I grew White Ghost peppers this summer which looked like that, but if they were white ghost you would know. The White Ghost has a faint bhut smell, I love them. I imagine a true whit hab would have a Hab smell or taste also just much milder.
Well CAPCOM I think it's suppose to be a chocolate hab but not 100% sure. I planted a bunch of different varieties in the spring and I didn't have tags for a handful of them. At the time I thought I'd remember which was which but obviously that was not the case. Hahaha
As for the heat I haven't tried it yet but will soon.
NorthEast_ChileMan I think you got it. Looks to me that they are the same.
