1. Greenhouse Management
Objective: Understand greenhouse structures, production and maintenance.

2. What’s the point of a Greenhouse?

3. What’s the point of a Greenhouse?
The “Greenhouse Effect”- collects and stores heat from the sun (radiant heat)
Provides a protective environment to grow plants
Many detached houses can be used as connected houses

4. Greenhouse Structures

5. Detached Houses
Quonset
Lean to
Even span
Uneven span

6. Detached Houses Advantages Disadvantages
Easy to program and maintain temperature
Easy to ventilate without exposing the plants to blasts of cold air
Requires more energy to heat and cool
Higher initial cost

7. Detached Houses
Draw an image and write a brief description of each type of detached house

11. Greenhouse Equipment & Controls

12. Greenhouse Equipment & Controls
Heaters- gas or electric
Thermostats- controls the temperature, should be at plant level
Timers-for lights, shade cloth, irrigation, etc.
Evaporative cooling systems
Most effective method for cooling a greenhouse
Constructed of thick corrugated cardboard
Reduces watering due to higher humidity created by evaporation from the dripping water in the cool pad

13. Greenhouse Equipment & Controls
Exhaust fans- pulls hot air from the greenhouse
Vents- located at the opposite end from the exhaust fan. Vents open to allow fresh air in the greenhouse.
Circulation fans- circulates air in the greenhouse even when the exhaust fan is not running. Provides a uniform temperature throughout the greenhouse.
Misting system- cools the greenhouse and provides a fine mist for seeds and cuttings.

14. Greenhouse Equipment & Controls
Overhead irrigation system- waters greenhouse or shadehouses but may not give the deep watering some plants need.
Drip irrigation- tubes with emitters go to individual pots for water. A very efficient way to water.
Lights- provide additional lighting for plants
