Getting the most from your retractable roof systems

The following series of educational videos will give you a detailed explanation for how automatic retractable roof cooling houses, greenhouses, field and orchard covers will improve how your grow, expand when you can grow and can change where you can grow.

Introduction

(8:08) Why leaf, fruit and soil temperatures are often significantly different than air temperatures in the direct sun, and how a roof covering alters plant temperatures.




1. Plant Temperature

(8:08) Why leaf, fruit and soil temperatures are often significantly different than air temperatures in the direct sun, and how a roof covering alters plant temperatures.




2. Water Loss or Transpiration

(5:40) How the rate of water loss from plants changes when plants are outside in direct sun compared to when plants are in a protected environment.




3. Hydration, Dehydration or Water Stress

(14:15) How plants respond based on whether they are experiencing low water stress, optimal water stress or severe water stress.




4. The Difference Between a Retractable Cooling House and a Conventional Greenhouse

How plants respond based on whether they are experiencing low water stress, optimal water stress or severe water stress.



5. Automating the Retractable Roof and Walls

(14:41) Creating the best possible growing conditions by combining plant physiology, nature, protection and a black plate temperature sensor.



6. Webinar: Preventing or reducing disease, insect damage, and fruit problems using retractable roofs (2 hours, 26 minutes)

  1. List of diseases, insects and problems of fruit quantity and quality

  2. The 4 climatic factors which impact plant health, fruit quality, disease, and insect pressure

  3. Plant responses to changes in the 4 climatic factors

  4. The limitations in managing the 4 climatic factors in the open field, in net houses, tunnels and conventional greenhouses

  5. How plants develop differently when they are exposed to the natural outdoors versus an indoor protected environment

  6. Disease: How to break all three sides of the disease triangle (host, pathogen, climate)

  7. Insects: How to prevent the need to move to more severe forms of treatment (Prevention, Cultural/ Sanitation, Physical/ Mechanical, Biological, Chemical)

  8. Problems with fruit quantity and quality: How to prevent Insufficient flowers, poor pollination, physiological problems affecting the fruit shape, size, firmness, color, uniformity

  9. Limitations: Problems that are difficult to solve using retractable roof.
