VIVOSUN 20 in. x 20.75 in. Durable Waterproof Seedling Heat Mat

VIVOSUN’s heat-mat technology hits that sweet spot temperature around 10℉-20℉ above ambient air temperature – perfect for seedling starting and cutting propagation, After covering with a humidity dome, the mat gets warm enough to create dew throughout the plastic dome, keeping your plants from drying out. Keeps a steady temperature and distributes heat evenly, even in the cold (with an insulating layer underneath).
