Here is an example of what is available online they are typically called a seedling heat mat…this one is sold by Burpee.
My husband pretty much found everything for free, although he did have to buy a plug. You know if you look around as you are driving down the road people throw away all sorts of things you can use for projects around your homestead.
Materials for this project:
stainless steel tray
pipe heating cable (12-15ft)
potting soil/soil amendment mix
electrical outlet plug
First my husband secured the cable to the bottom of the metal tray with some heavy foil tape. He then set the gravel on top and then filled it with soil mixture. Next he wired the heating cable to the thermostat and mounted it to the side of the tray. He then installed the electrical plug and made sure everything was properly grounded.
And then we have our own DIY Seedling Heat Tray!
We planted some tomato, ghost pepper, and some Texas Blue Bonnet seedlings that all came up within 2 to 3 days!
This might be a project you may want to do if you have the electrical skills on your homestead. I know I would not have done this project myself but it was really neat to see him put it together and its going to be a lot of fun to experiment with seeds with it this winter!
Happy Planting to all those who are seed starting now!
