Types of Greenhouses

There are various greenhouse types to choose from, each catering to different gardening goals and space requirements:

Benefits of Portable and Small Greenhouses

Small and portable greenhouses are particularly popular due to their affordability, ease of setup, and flexibility. They can be moved to different areas in your yard, stored during off-seasons, and provide a controlled environment for seedlings, herbs, and small crops.
