General rule of thumb.
Best heating mat temp for rootiny.
The top of my electric water heater has proven to be a reliably cozy place to put a small tray of seedlings.
8 x 12 inch 20 x 30 cm 16 w.
You can either get a self regulating heating pad that maintains a temperature of 37 degrees above room temperature or you can get a heating pad that can be controlled via a thermostat.
For the thermostat you can set the temperature between 40 150 f.
27 29 is too hot floor surface temp should be around 23 which will give room temp of 21.
Almost all quality plant heating mats come with a built in safety shut off that will trigger when the heat mat reaches a temperature of 10 degrees above the room temperature.
You can set the temperature to the exact degree that works best and the exact amount of time that you want heat within given ranges.

The heat settings range from 113 degrees fahrenheit at the lowest setting to 166 f at the highest.
At least that is what the marketing material mentions.
Soil temp stays dialed in at 78 deg f when thermostat for the water is set at 125 f.
Most seeds need soil temperatures somewhere between 70 f and 80 f for optimal germination and heating mats without a thermostat usually heat somewhere between these two temperatures.
Cuttings of most plants root best when the rooting medium is at about 70 degrees though temperatures as low as 55 degrees are acceptable.
One almost surefire method is to use a seedling mat an electric heating pad that sits under the seedling trays usually regulated by a thermostat.
Ideal temperatures for germination depend on the plant but generally speaking seeds need a consistent temperature of between 65 and 75 degrees.
The vivosun seedling heat mat temperature stays between 10 and 20 degrees f above the ambient air temperature.
Heating the rooting medium above 75 degrees isn t.
Obviously near the manifold the floor temp will be higher.
You may be wondering what wattage your heat mat should be to provide the best heating for your leopard gecko.

In our experience the temperature of the heat mat never gets too high when ambient room temperatures are in the 70 s or lower.
