12 Things To Consider When Selecting Greenhouse Site - Pest Pressure & Level and Stable Ground

5. Pest Pressure – Choose a site away from existing agriculture production areas which could harbor insect pests in the fields. Insect pests of concern include white flies, aphids, spider mites and thrips (see here for pests and control methods).

6. Level and Stable Ground – The ground upon which the greenhouse will sit must be

• Graded for routing surface water to a drainage system or a holding pond. (Typical grade = ½ % or a 6 inch drop over a distance of 100 feet.)
• Compacted such that there will be no settling of the site after the greenhouse has been constructed.
