My grow is over a quarter mile from the house so no fans (I'd need several). It's been a real chore to haul water, I can tell you! We have a pond nearby but the drought's been so bad, I am questioning the water quality this year. Hence, filling a lot of containers at the hydrant and hauling a few at a time with a truck or ATV.
I've been through frost before but usually a little later. It's a very anxiety-provoking time. There is only one night that is expected to go to freezing (31) over the next couple of weeks a lots of sunny days so I'm pretty confident the buds will be able to finish to perfection without taking extraordinary measures
