What to use for bottom heat source for seeds?
I got my shop lights today, and have my shelves and a large oscillating standing fan. And I got my seeds and planting mix.
Now I just need to figure out what heat source to use for my seeds. Can someone suggest some inexpensive ideas? The room where I will be growing these seeds has a south facing window, but is kept around 66 degrees. So I think the plant trays will need a heat source.
