Suggest an oil filled radiant heater. No risk to the gasoline. Something like this:

Amazing heaters. Used them when raising the younguns. Safe efficient and cheap.

definitely a decent heater, im using 1 as we speak

That temp is cold enough to cause cellular damage. If it was just the one night and you may get lucky. But if they get any ice or frost that actually forms on them, the area it forms on is done for most of the time.
Oil heater or hps lights, heat lights something to keep the Temps up or they will be gone if not all ready…
Got any pictures and maybe give us a better idea

Installing a temperature controller, a device that allows us to adjust the air intake and keep the air temperature well within the optimal values, thereby preventing any difficulties caused by extreme temperature swings, is a simple approach to avoid this problem. I've been in a similar situation before and installed an electric warmer; nevertheless, this has drawbacks, most notably its high electricity usage, which I believe is not realistic for most people. One of my friends who works in a [cannabis store](https://thestashandco.com/pages/ottawa-centretown) recommended utilizing a temperature controller, and I've been using it ever since.

Try insulating the pot and rootball. Most plants as long as the nip is contained to the leaf and the roots stay warm they’ll be fine!
Over short periods.

Styrofoam cooler. I got a couple of freebies but they are too small for my 3-gallon pots but might work is I do a short run in 1-gallon pots.

How does it get to 10° and you not be proactive ahead of time? Didn’t you get notification of cold weather?
