Hey, cayenne peppers can be successfully grown anywhere under the right conditions. The plants need approximately 14-16 weeks to mature. Peppers prefer warm, evenly moist, nutrient-rich soil, warm temperatures, and full sun.
The longer the cayenne peppers remain on the plant, the redder they become. Don't be fooled though, green pods are just as hot. Remove and use fresh as needed. Whole peppers can be dried on the plants or removed and spread out in a warm, dark room. Be sure to store the darn things in an airtight container.
I hope I have been helpful.
