The weather makes a big difference. Just look at how hot August peppers are compared to peppers from the spring or fall. I keep mine in greenhouses where they stay about 12 degrees hotter than it is outside. This increases the hear of my peppers. Then I found a nutrient that I used in a side by side test, and from taste alone, the subject plants produced peppers about 300k hotter. They were a good 20% to maybe even 30% hotter tasting. I thought about this year hitting some Primos real hard so that they may rate higher than a reaper and get some tested, but I was so busy with cycads this season, and just coping with tripling my pepper production plants, I didn't have time to play with experiments. I tell you, I have tried a lot of the new really hot peppers, but the primos and reapers still burn the worse when you find a good one. Tom
