Not only did these all sprout (ok... like 99.9% germination) in simple starter trays, I can easily say these are the hottest peppers we have grown. We washed our mouths out with reaper's to dilute the heat -no joke. Chocolate Bhutlah don't test consistent on the scoville scale, so the average rating leaves them below reapers and that new one (which I Haven't tried), but these specific plants from this seller - are just awesome. I was able to mix down a sauce after a few attempts that leaves you licking your fingers uncontrollably, while feeling the effects of napalm - which was my goal. They fruited very well, and I took all down to the three biggest plants, which have been producing like crazy. A little care, maybe a bit of research if you're new to planting any kind of seeds, and you cant go wrong. (the attached pic is these, mixed down with scotch bonnets and jamaican yellows- don't touch your face while eating anything with this on it - but you wont stop eating the thing - awesome)
