Viagrow 20.5 in. x 8.5 in. Seed Propagating Seedling Heat Mat

Studies have Proven that plants with a root zone that is kept warm thrive & propagate at a much faster rate than plants that do not. Simply place the seedling heat Mat on a flat, dry surface under a seedling tray & plug the cord into a 120 v outlet. For best results, use propagation dome over the seedling tray & keep it under T5 fluorescent lighting or in a greenhouse lighting environment. Direct sunlight or high HID lights may be too intense for seedlings.
