I know that before the pepper plants can be exposed to 12 hour sunlight, you need to harden them by giving them 1 hour of sunlight everyday. But here in Miami, they plants start to wilt almost to the point of death in just under 15 minutes. Maybe it's to hot and humid or something. But I take them outside and the leaves start to curl upward really fast so I bring them back inside and they go back to their merry selves. Is there another way of doing this? Is there some type of oil or nutrient I can spray on them to promote hardening?
