TRANSCRIPT
GreenhouseGreenhouse: Building used to house and grow plants - Climate can be controlled
- Amount of water- Temperature- Nutrient levels- Humidity
Uses:- Extend the growing season - Grow plants in areas that are colder then their
natural habitat (tropical plants)- Run controlled science experiments
Types of greenhouses
Cold Frame: An open bottom box with a slanted clear roof
Purpose: To extend the growing season used to extend the growing season. Protect plants from cold or wet weather
Types of greenhouses
Lean to: A clear panel structure built off the side of a building

Constructing a greenhouse1) Hoop House: Easiest
and Cheapest greenhouse to build
Materials: - PVC piping- 4-way connectors for
pipes- Greenhouse quality
clear plastic
Steps in building a hoop house
Example: A 5 hoop house1) Collect your materials5 hoops: 10 lengths of PVC or metal pipe 3 four-way connectors 2 three way spacers for the ends 5 2 foot spacers to spread out hoops 10 ground pegs Plastic covering: 1 sheet of clear plastic 2x the length of the PVC pipes and 2n in length where n = the number of hoops
