Seedling Heat Mat Seedling heat mats offer versatility and portability for all your horticultural needs. Sizes are available for various hobby and commercial applications. The durable double-layer construction is waterproof, and makes them ideal for greenhouses, nurseries, and hydroponic hobby gardens in need of maintaining a specific root zone temperature for valuable crops. Instructions: 1. Place the mat on a stable dry surface this side up. 2. Plug the mat into a 120v source only. SPECIAL NOTES: PLEASE READ BEFORE OPERATING • To maintain stability in the root zone temperature we recommend a digital Heat Mat Thermostat (item# MTPRTC) and an insulated surface for optimal control. • Covering the seedling or cuttings propagation trays with a humidity dome will help ensure consistent temperature regulation. • Seedling heat mats are designed to raise the root zone temperatures approximately 10 to 20 degrees Fahrenheit above ambient air temperature. • Seedlings and cuttings prefer light that is not too strong, such as hot, direct sunlight. Full spectrum fluorescents are an optimal quality light source that works excellent when placed a few inches from the humidity dome or plant tops. • High intensity discharge lighting is adequate for seedlings and cuttings as long as it is placed at safe distances, such as the ambient light and not directly underneath. • Seedlings and cuttings should be kept moist, not wet. Do not allow excess standing water as this could lead to damping off. Overwatering is just as undesirable as not enough. • Transplant the seedlings or cuttings when a healthy network of roots (multiple white roots) has formed out of the starter cube. WARNINGS: • Fire or electric shock may result from improper use. • Make sure that the surface under the mat is free of sharp points or objects which might puncture or damage the mat. • DO NOT place the mat inside the propagation tray or cover it directly with soil or any other growing medium. • DO NOT immerse in water. • DO NOT place any heat insulating materials over the mat as this could cause it to overhea
