Never tried it, but you should try just to see if it would be a good option for you. I am in zone 9b and I left the majority of my echeverias outdoors during the winter. I left them in their container plantings, had the containers banged up against the house under the eaves and put a frost cloth over them every nite. Our lowest temp was 29 degree F but I assume you have lower temps and more moisture in WA? You can always leave one outside in a protected area and leave one indoor under artificial lights and see how it goes.

Our winters vary from year to year in term of lowest temperature. This winter the coldest it got was around 16 degrees F. The one thing that stays constant is the rain. It rains a lot in the winter!

My husband is an electrician so he is going to make some growing lights for me. I'm really interested to see how the echeverias will do. I will keep you guys posted.

I winter most of my plants and I use T-8 fluorescent shop lamps. My table is 4 ft. x 2 ft. and one 4 tube lamp about 1 foot above them. Works fine but put on a lamp timer switch. I keep it 12 on and 12 off. It may need less light to induce their winter sleep. On my Sanserieria plants, I noticed some variegation is lost. More all green grows on new leaves. Natural sun works best. of course.
BTW I am a retired electrician/instrument person myself.
