How Long To Use Heat Mat

Posted by thedoggroomer (My Page) on

I planted some petunia seeds 3 days ago and they're already up using a heating mat. Unbelievable. Now, they are growing under fluorescent lights - once they have germinated (even though the leaves are tiny), do I discontinue the heat mat? The room temperature is approximately 70*.

RE: How Long To Use Heat Mat

Soil heat is used only for germination. Once the seeds germinate the warmed soil can quickly cook the tiny seedlings, especially roots.

For growing-on cooler air temperatures are recommended. 60-65 degrees is recommended.
