Happy New Year! Today I started doing some tests with my new toys I got for Christmas. Pictured here is my new seedling heat mat. Normally you would use this to warm the soil in your pots but I'm trying it for my seed starting. It will take a little experimentation to get the temperature just right and make sure it doesn't fluctuate much. Every hour or so I'm using a thermometer to check the temps. When I first started out and didn't have the seeds on the mats I found that temps were around 75 degrees with the mat sitting on the shelf. I put a towel under the mat and temps went up to about 85 degrees. I then add the zip lock bags with the seeds and checked the temps but found that zip lock bags were trapping heat and the temps were getting up to about 92 degrees and I'd prefer it around 88-90 degrees so I've removed the towel and seeing what that does.
