Viagrow Seed Propgating Seedling Heat Mat, 20.5" x 8.5"
Place the ViagrowTM Seedling Heat Mat on a flat, dry surface and plug the cord into any 120V outlet. Place the seedling tray directly on top of the heated mat.  For best germination results, place a propagation dome (#VTD300) over the tray and keep it under T5 fluorescent lighting (approximately 300-800 foot candles.) Direct sunlight or high HID lights may be too intense for seedlings.  As a general guideline, seedling and clones grow best with temperatures of 70-80 degrees and humidity range of 50%-60%.  Please be sure to research your particular plant as temperature and humidity requirements vary for different species and hybrids. Dimensions are 20.5 x 8.5 in, and it is 18 watts.
