I need to keep plants hot in an ice chest. How can I for a long period of time?
I need to keep plants hot in an ice chest. How can I for a long period of time. It’s for a science project. Right now I have a heating pad in the ice chest with them but it’s not getting very hot? Any other way to do it safely and cheaply?
It’s for a science project my daughter is doing. I have 1 ice chest with a large frozen milk jug of water. We are comparing the growing rate in cold vs hot temps.
Light bulbs are great – come in different watts so you can adjust the heat. Use a "trouble light" that has a cage around the bulb – if the plants need to be in the dark, use aluminum foil to block the light.
