Direct planting in soil: Free and natural-looking, but may not be as stable and may require additional reinforcement. Also more susceptible to pests and diseases.
Concrete pad: Durable, stable, and long-lasting, ideal for heavy greenhouses. However, it's expensive and time-consuming to install.
Paving stone, slabs or breeze blocks: Cost-effective and easy to install, but less durable than concrete. May not be as level or as resistant to moisture.
Wooden base: Affordable and customizable, but requires regular maintenance to prevent rot. Can be less stable than other options.
Steel base: Extremely durable and long-lasting, but also expensive and heavy. Installation can be challenging.
Plastic base: Lightweight and easy to transport, but not as durable as other options. May warp or crack over time.
