If stressing plants make peppers hotter and mine survive I would surely have the worlds hottest peppers. In terms of stress my plants had a nervous breakdown today. When I brought my tray of 3 inch plants out to fertillize them I ended up dropping them trying to get back in the house. Then as I'm salvaging plants I realize I got the amount of fettilizer wrong and gave then full stength. So I had to flush them with tap water. I'm ready to have a nervous breakdown.
