Viagrow 20.5" x 20.5" Seedling Heat Mat (Case of 25)

Studies have proven that plants with a root zone that is kept warm thrive and 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 and plug the cord into a 120 V outlet. For best results, use propagation dome over the seedling tray and keep it under T5 fluorescent lighting or in a greenhouse lighting environment. Direct sunlight or high HID lights may be too intense for seedlings. Warms root area 10-20 above room temperature Speeds germination and encourages strong root growth Fits snugly under 2 standard size seed trays High quality, water resistant construction May be used with a compatible thermostat for temperature control Size is 20.5 in. x 20.5 in.
