My greenhouse heater gave out during that cold snap in February
Some folks say a backup system is essential, others think it's overkill for a hobby setup. What's your fail-safe plan for protecting plants from a sudden equipment failure?
Honestly, that's a pretty clever hack. Those old bulbs do pump out a surprising amount of heat. Just watch they don't touch anything that could catch fire.
Remember trying that in my old apartment and my cat tried to use the bulb as a pillow. Woke up to a weird smell and a cat with a warm, lopsided ear. I mean, it worked for heat, but I spent more on vet bills than I saved on my heating bill. Probably should have just worn another sweater.
