A small greenhouse can also work outdoors for starting your seedlings in early spring before the ground is ready for use.

These greenhouses are also known as mini greenhouses and are available in starter kits which include grow lights, if you need them, the starting medium and include small containers. Many of these kits are available with transparent covers to keep in the moisture.
