The difference between a retractable cooling house and a conventional greenhouse
10 Steps To Creating Your "Retractable Roof Production System" ™ based on your climate and crop requirements
Step 1: Decide if stationary or retractable insect net is required under the retractable roof
Step 2: Choose the house model
A-Frame, Rafter, X-Frame or Flat Roof
Step 3: Choose the roof covering
White cooling roof or Clear greenhouse roof
Step 4: Decide how to ventilate in peaked roof house when it is raining
Through the perimeter walls if the house is less than 1 hectare or by installing a rain canopy on every 4, 5 or 6 houses if the house is larger than 1 hectare
Step 5: Determine optimal house orientation to ensure that shadows and sunlight are always moving across the crop.
Step 6: Decide if additional climate control is required:
a. Fog or low-pressure mist
b. Retractable interior curtain systems for cooling, heat retention, insect control or blackout
c. Bird net
Step 7: Choose perimeter wall design for each of the 4 walls
a. Choose wall covering: Stationary insect net, white cooling covering or clear greenhouse covering
b. Is white or clear wall covering going to be stationary or installed on a motorized roll up curtain?
c. Will insect net be installed over the roll up curtain opening?
d. Will roll up curtain extend down to the ground or to a kneewall?
Step 8: Decide if crops will be grown in soil or hydroponically
a. If hydroponically, chose whether the container will be white or black
Step 9: Determine number of growing zones and plant density
Step 10: Decide if the climate control computer that will automate control of the roof, walls and misting system will also control internal growing systems like irrigation, fertigation and heat
