Viagrow™ Two Tray Seedling Heat Mat, 20.5" x 20.5"

• Warms root zone 10° - 20° above room temperature
• Speeds germination and encourages strong root growth
• Fits snugly under two standard size seed trays
• High quality, water resistant construction

Place the Viagrow™ 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.

*For precise temperature control we recommend operating heat mats with heat mat thermostats and a thermometer to accurately control and monitor temperature. See products 726702 & MTPRTC.
