It is amazing the difference in the heat level of peppers when they are being abused. I have two mushroom pepper plants that I have been doing an experiment with all summer. At the beginning I gave them all the compost and water they wanted. The first peppers were nearly the same heat level between the two plants. I actually will grow these peppers again as the taste is definitly something I have added to all my salsas this year. HOwever, I turned off the water and compost to one plant in July, only giving it enough to keep it going, usually only watering it when it got limp. I am here to tell you it makes a huge difference in the heat of this pepper. The difference in heat was obvious, and the placenta and seeds almost inedible due to the heat. I can't wait to try this with a Naga next year.
