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.

well, how hot do you need them, are you cooking them or sprouting seeds? and why does it have to be in an ice chest anyway? I"m assuming it's for the insulation to hold heat in. you could try a heat lamp similar to what is used for baby chicks, these are available in farm supply stores, maybe even just a trouble light would do. I think you can regulate the heat to a certain extent, maybe add a thermostat. Just remember you are playing with a serious fire hazard, so I"d at least put a smoke detector nearby.

Put a sheet of clear plastic over it to keep the heat it. It is called the greenhouse effect.
