Seeds need to be warmer than room temperature (75-80 degrees, to be exact) to sprout, and so you will see a much higher germination rate with a heat mat. Spider Farmer’s Seedling Heat Mat warms the root area of seedling 50-77°F above the ambient air temperature, significantly improving the germination process and the success rate of seedlings and cuttings.

The current Clip Fans with RJ12 ports also support fine control, allowing you to set fan on/off timesstandby speed (for lower speed operation after runtime ends), and oscillation range. You can even simulate natural wind (from the speed you set to the L1 speed in a back-and-forth motion). If your Clip Fan or Inline Fan does not have an RJ12 port, it can still be controlled through the GGS Power Strip. If you’re unsure how to check whether it has an RJ12 port, please refer to point 4 in the description. The kit includes:
