T.O. Plastics 10x20 Humidity Domes are designed to work like a greenhouse. These pieces of clear plastic fit perfectly over T.O. Plastics standard 10x20 seed trays. The idea behind humidity domes is to capture heat and retain moisture – both variables that improve and quicken seed germination. 

There are several advantages of using humidity domes to start seeds. Humidity domes trap heat and moisture during a time when seeds need these particular conditions the most – during germination.

Humidity domes are proven to speed up the germination process. By design, humidity domes hold in the moisture that most seeds need to sprout.

While seed protection might not be the primary purpose of a humidity dome, it certainly can accomplish this purpose! Humidity domes are perfect for creating a barrier for birds and other animals from getting to your seeds.
