What ever works. I have thought about using a small hoop green house with a 100 watt bulb outdoors in the winter too.
What keeps me from it, is my aversion to cold weather. I wouldn’t want to even go outside long enough to turn the light on or off.
It’s great that we have various options to grow our own stuff, I think.
I’ve been known to go out with a jacket and gloves to cover plants at 9 PM to make sure they don’t freeze. I learned from my dad to do everything you can do to save plants.
