A1: The temperature inside the greenhouse may be 20-40 degrees during the day and the same as the outside temperature at night. This is in the absence of any supplemental heating or cooling. So we recommend to add a heater inside greenhouse Q2: Will it stand up to heavy wind? A2:This greenhouse can stand up to 56 mph wind at least. Q3: Why use different panels on roof and wall?

Crystal-clear shatterproof polycarbonate wall panels ensure your plants have enough light to grow.
