I’m looking for recommendations on how to safely heat my little 6×8 corrugated plastic greenhouse. I’ve sealed all the cracks, added brick on the inside and outside of the base with bubble wrap between and added an extra plastic door to the inside of the sliding door. I hoped to be able to thermally heat it with the addition of a black bucket of water and a 2×2 raised dirt bed but overnight temps drop to just above outside temps. Are there heaters that would be safe to run overnight in here? Or would a heat lamp be enough? Or other ideas?

Did it drop below 50 f or 10c? If not, don’t worry about it. If it did, how cold?
You could try placing a large black container full of water (+50 Gallons) in a spot that gets a lot of sun and see if that helps keep the temps inside.
Bought a timer from Amazon to turn on and off electric heater during the coldest times of the morning here in 9B. Seems to be working great.
Would avoid using heat lamps, so many horror stories regarding them.
It really depends on your outdoor temps and how much you actually need to heat your greenhouse. If thermal heat from your black buckets of water isn’t enough, you can get a tiny bit more heat from incandescent Christmas lights.
A radiant heater is a good safe option.
