Growing pumpkins indoors is possible but not recommended for most varieties. Pumpkins are typically large, vining plants that require a lot of space, sunlight, and airflow. Growing them indoors can be challenging due to their size and the need for pollination.

However, some smaller or bush-type pumpkin varieties might be more suitable for container gardening indoors or in a greenhouse setting. These varieties are specifically bred to take up less space and can be more manageable for indoor cultivation.

If you have limited outdoor space, you might consider growing compact pumpkin varieties or other types of small gourds that are better suited for container gardening.
