Seedling Heat Mats
Heat mats can both increase germination rates and help you achieve more uniform germination by giving you control over temperature — one of the environmental factors most closely linked with germination. They also decrease production time by maintaining optimal root-zone temperature, thereby increasing growth rates in the early stages of a plant's life cycle. Johnny's offers heat mats in range of sizes, from small to large add-on commercial styles, as well as thermostats and control devices for precise circadian regulation of bottom temperatures.
