A solid foundation is crucial for stability and preventing pests.
The materials used to build the foundation of a greenhouse include :

* Pressure-Treated Wood: A common choice for smaller greenhouses, providing a durable base that resists rot.

* Concrete: For larger or permanent structures, a concrete slab or footings offer the most stable and long-lasting foundation. This also helps with thermal mass, storing heat during the day and releasing it at night.

* Gravel/Crushed Stone: Can be used as a base for smaller greenhouses, allowing for good drainage. It's often combined with a perimeter of wood or concrete.

The type of fasteners you need will depend on your framing material.
The materials that can be used include :

* Screws: Self-tapping screws for metal frames, or specialized wood screws for timber construction.
* Bolts and Nuts: For securing heavier components or joining structural elements.
* Clamps/Clips: For attaching polyethylene film to frames, especially for hoop houses.
* Connectors: Specific connectors are used for PVC piping to create the frame.
