I have these from rareseeds, idk how well they'll do. They look fine at the moment, they just haven't grown much which I assume is from the 105+ temps.
Do you have to take measures to separate the varieties of peppers? Do they cross-pollinate or something?
My ex-father-in-law grew some hot peppers that were disappointingly mild, and blamed some sort of cross-pollination from the mild peppers next to them. I have no idea whether that is a legitimate claim, though
If all the fruit was weaker than anticipated, that is the genetics of the seeds he planted. Fruit can have a variation in different spots on the plant in heat, but the mild pepper next to it had no effect on that.
