There are actually different heating pads that you can buy from gardening specialty stores but there are also some seedling heating options that you can do. Probably the easiest way to get heat to your seedlings is to place the seed flat on the top of a refrigerator, television or other appliance that puts off a considerable amount of heat. Or if you want an enclosed area for your seeds, you can build a light box with incandescent bulbs. It's up to you if you want to use a free standing light or a desk lamp if you donÂt want to do electrical wiring yourself.

Steve,

I have used a heating blanket with success. If you have one of those you might try it on a medium to high heat setting...
