I’ve never tried this but how about one of those small DIY greenhouses?
It’s super easy to build a greenhouse for very little money. My greenhouse, used commercially, is an old Costco “barn” someone was throwing out. I spent $125 on good quality greenhouse plastic and another $100 or so for automatic vent openers and then reinforced it all with scrap wood. Another small farm down the road built one mostly out of old windows they got from a neighbor who was replacing theirs.
You can also just make a smaller cold frame with an old window and/or plastic. It’s also really helpful to have frost “blankets”, either as old used blankets/comforters or row covers like Remay or Agribon. I use Agribon 50 which gets you about 8F of protection. Not very environmentally friendly though!
