This chart shows the range of soil temperatures needed for seed germination.
Temp needed for starting seeds on a mat.
Read the back of the seed packet to verify the temperature requirement of your seeds.
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.
Because we live off grid we needed to find another way.
Using a seedling heat mat is the cheap and easy way to provide the optimal conditions for your vegetable seeds.
How do you achieve this idyllic consistent temperature.
Other near equal factors include seed vitality the age of the seed soil moisture soil air and soil conditions and workability.
Vegetable seed germination is greatly dependent upon soil temperature.
Outer limits for all seeds for microgreens range from 50 degrees f 10 degrees c to 85 degrees f 29 degrees c.
The germination mat helps keep an even germination temperature between 65 80 f.
The temperature varies on what you are growing.
The warmth that most seeds do need is commonly called room temperature around 70 degrees f 21 degrees c during the day though somewhat lower than that during the night.
Set the heat mat to the proper germination temperature for the type of seeds you are growing.
Our seedling sprouting area is near our windows and since we start our spring garden seedlings in january it can get pretty cold for them.
A lot of people these days will purchase heating pads to germinate trays of pepper and tomato seeds.
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.
Most plants require a soil temperature of 70 to 72 degrees fahrenheit but some plants like peppers require warmer temperatures of 80 to 85 fahrenheit.
However you can speed up their germination process when you provide more warmth for vegetable seeds.
With a heat mat we can ensure quick and reliable sprouting for our vegetables.
Ideal temperatures for germination depend on the plant but generally speaking seeds need a consistent temperature of between 65 and 75 degrees.
