I use my workshop for all things grow-related, and my workshop is not as warm as the rest if the house during the winter and we keep the house at 68 degrees in the winter anyway. I have a small warming mat I use for seedlings when I start them for the garden in February. The mat works exceptionally well and I have found it maintains a very consistent temperature. I have put it to work now as a heating element in the grow cabinet and darned if that cabinet doesn’t hold a steady 75 like it was made for this task.
I watched Kyle Kushman’s video on germination and he said to keep the seeds at around 70-77 degrees, which is the sweet spot for the mat. However, I wonder if, with two plates semi-sealing the seeds and water in the sealed area, it wouldn’t get too hot for the seeds by retaining the heat rather than letting any escape.
Thoughts or experiences from experienced growers?
