Frequently Asked Questions (FAQs)

1. Should a greenhouse be waterproof?

This is a hazard best avoided. It's a fact that no greenhouse is 100% waterproof! Water can come in under the bottom of the base, from watering spills or from an occasional leak and so it's very important to allow the water somewhere to escape naturally.

2. What metal is used in greenhouses?

Although aluminum is used in greenhouses, steel is almost always the material of choice for the structural components of a commercial greenhouse due to strength. Not all grades of steel are equal.
