night time temperature for peppers
Planting time. Hot peppers grow best in daytime air temperatures 65Â° to 80Â°F and night temperatures above 55Â°F (nighttime temperatures between 60Â° and 70Â° 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.eppers prefer a soil pH of 6.0 to 6.8. If the pH is below 6.0 add limestone to the soil; if the pH is above 8.0 add peat moss to lower the pH. A safe bet is to always work aged garden compost into beds prior to planting. The optimal soil temperature for peppers is 65Â°F or warmer.
