I liked tefers heater link. I do fear that beeks will be hoarding all the incandescent light bulbs though. It would also be wise to wire that baby into a GFCI circuit. Liquids and electricity is not the most fail proof of systems
Anytime I've tried to save money and make my own I end up spending the same money, lots of time and it doesn't work as well.......then I buy what I should have in the first place so I'm really out twice as much plus my time. For once I said screw it and just paid the money.
LOL, isn’t this the TRUTH!!! I can’t even count how many times I’ve wasted time and money re-inventing the wheel.
