Question: what is the best temperature to grow hot pepper?
Answer: Hot peppers grow best in daytime air temperatures 65° to 80°F (18-26°C) and night temperatures above 55°F /13°C (nighttime temperatures between 60° and 70° are best). Peppers are most easily grown from transplants. Start seed indoors 7 to 10 weeks before the date you intend to set peppers into the garden.
