Want A Seedling Heating Mat? You May Already Own One!


When starting seeds indoors, one way to get your seeds to sprout faster is to offer a little extra warmth while still keeping the soil mixture moist. You can buy germination heating mats to place under the containers or make your own like I did here.
The idea actually came to me when I was putting away some decorative LED rope lights during the holidays and I noticed they were slightly warm. Perfect temperature for gently warming my seedling containers!
-Simply string the rope lights back and forth in rows along the shelves and sit the water-tight seedling containers on top of them. No need to tie the lights down-the weight of the containers holds them in place.
-Most seeds don't actually need light until they have germinated so just move them to the grow lights once they have sprouted. .
Make sure you read the label on your lights. MIne says it's fine to leave them on but do not ever submerse them in water so I make sure all of my containers do not leak.

LED rope lights to the rescue. Don't just pack them away after the holiday season!

    Lorna, LED lights are different and give a better and more organized lighting spectrum for your plants!!! I.E..the choice for LED lights.

    These have to be incandescent rope lights not LEDs to put off heat. The LED rope lights are cool to the touch.
