  2. Laying the Foundation: Structural Parts of a Greenhouse • Sidewall: supports the entire weight of the greenhouse. Consists of the following parts - • side ventilators • side posts • curtain wall • Concrete footer: foundation for the side posts • Eave: area where the sidewall joints connect • Sash bar: bar made of metal or wood that runs from eave to the ridge, holding glass in place

  3. Laying the Foundation: cont.. • Roof: provides cover. Consists of: • sash bars • purlins • roof ventilators • ridge • Purlin: bar running length of roof that supports the sash bars, holds bows and trusses upright • roof and side ventilators: allow ventilation during light rain • ridge: peak of greenhouse • shutters: operate like windows to allow air flow

  4. Greenhouse Shapes • Even-span greenhouse: self supporting with distance from ridge to eave equal in distance • Ridge & Furrow: two or more even-span greenhouses connected at the eaves. • Quonset: arch-shaped bows placed in a row. Appears tube shaped - most common shape • Sawtooth: greenhouse with a vent near the eave of the lowest side wall that allows for natural ventilation.

  5. Greenhouse Shapes cont. • Lean-to: a greenhouse already attached to a existing structure. • Gothic: Slightly pointed greenhouse covered with corrugated fiberglass

It is a lot of money and time to throw away if you don’t obtain as many facts as possible before you build. • Factor 1: Accessibility • Factor 2: Expandability • Factor 3: Markets • Factor 4: Orientation

  7. Factors to consider: cont. • Factor 5: Personnel • Factor 6: Topography • Factor 7: Utilities/water

  8. What does this mean for greenhouse management? • It is not as easy as just going outside and building a greenhouse. There are things to considered just as in any situation. So remember, depending on your location and climate, you will have to consider the • shape of design • location • utilities • market • personnel
