Creating an environment conducive to healthy plant growth will make or break your propagation system. Temperature is a crucial aspect of this environment, and seedlings and clones do best in a range of 75-80 degrees Fahrenheit. It is uncommon for this to occur naturally, especially in certain climates, and thus most growers use a seedling heat mat.
What is a seedling heat mat?
These mats are a very simple way of increasing the temperature in your propagation system by 10-20 degrees Fahrenheit, and are relatively inexpensive. Most mats are set to provide a temperature of 78 degrees, which is perfect for seeds. After the seeds have germinated, the plants should be kept at a temperature between 68-75 degrees.
Using a hygrometer can help growers maintain optimal temperatures. It is important to ensure temperatures do not extend outside of the ideal range, as this will dry out plants. The plant will have trouble holding onto oxygen, and this leads to an inability to absorb nutrients, while creating an atmosphere where algae can become an issue.
