This heavy-duty 1020 clear humidity dome is ideal for lettuce and garden seedling germination. Two adjustable vents help regulate temperature and humidity inside the dome.

The heavy-duty BPA-free #3 plastic (the same plastic used in drinking water pipes) will not bend under the weight of a towel if you need to place your seeds into a blackout period for germination.

The clear humidity dome fits on the 1020 trays we sell and has an interior height of 2-1/2-inches.

*Note: The product does not include the black trays.
