The roll-up bars on the sides of the greenhouses gives greater control of temperature, air circulation, and evapotranspiration. Increased control of ventilation aids during times of variable temperature and humidity. When the the temperature or humidity in the greenhouse is high, the bars can easily moved up. The insect mesh is under the retractable plastic sheeting, which still reduces the pests within the greenhouse.
If the strings tying the bars break, use available string to replace. If there is a tear in the glazing material of the roll-up bar, follow the recommendations in the next section, Common Repairs.
