This could result in damage to your structure or sunlight blockage.
Allow ventilation on hotter days. An excessive amount of warmth isn’t always a very important thing – and that’s the benefit of a cold framework greenhouse. Since outdoor sunshine and temperature impact a cold frame’s inner temperature, easily change your cold framework during unseasonable heat waves. During these occasions, open up your structure and invite sufficient airflow to provide plants desired warmth without suffocating them.
