120V Plant Seedling Growth Electric Heating Pad Gardening Seed Germination Warming PadSeedling heating mat is one of the most important and effective ways to improve germination and rooting.It increases the success of seedlings and cuttings by warming plant roots and maintaining a controlled temperature all season long.The stronger heating wire and thicker multi-layer construction offer more uniform heating and the durability to withstand rugged greenhouse environments.With the ability to warm root area 50\u2109 to 68\u2109 over ambient temperature、 this heat mat will work even in drafty places.Making your plants to spend a warm winter with this heating mat!Specification:Material: PVC + heating coilSize: 20.5x9.2!#!amp!*!quot;(L*W)Thickness: approx. 2.5mm \/ 0.09!#!amp!*!quot;Power: 17WVoltage: 120VPlug: US plugCord length: 6 feetApplication: seed starting、 home brewing、 terrarium warmingFeature:Constantly maintains temperatureEfficiently improves root growth and germination timeOptimizes seedlings and cuttingsInnovative water resistant constructionPackage Contents:1 x Seedling Heating Mat (not include plant tray)1 x Outlet Plug (matching according to different countries)                                                                                                                                                                                                                 INSTRUCTION:           1. Place the mat on a wet drained surface (without standing water)           2. For wamer mat tempratures、 place it on an insulated surface rather than a cold floor. Covering your plant tray with a humidity cover or dome will also keep root area warmer、 and maintain humidity control for better rooting.           3. Plug the amt into a 120 volts power source.           4. This mat is designed to raise rooting area temperatures approximately  50-68\u2109 above ambient air temperature.                      WARMING:           - When ambient temperature is at 18\u2103 to 20\u2103 (64.4\u2109 to 68\u2109)、 the temperature of heating mat is 10 \u2103 to 15\u2103 (50\u21095--59\u2109) warmer than envrironment temperature.           - The  mat can not change the temperature.           - Fire or electric shock may result from improper use.           - Make sure that the surface under the mat is free of sharp points or objects that might puncture the mat.           - Do not place mat inside tray or cover directly with soil or growing medium.           - Do not place any heat insulating materials over heat mat、 as it may cause it to overheat.           - DO NOT IMMERSE IN WATER.
