I’ve tried the indoor thing we have a 6 foot slider due west but Michigan is not the best state for sunshine. I brought in a young volunteer tomato plant one fall and tried to keep it going. It got long and spindly and gave me one tomato! I do alfalfa sprouts sometimes but that’s about it.
Well, that’s why I have the grow light to use for those cloudy Missouri days, and also to extend the “daylight” hours for 2-3 hours each day.
The new grow lights last a long time, and use less electricity than my other lights, so I just use them and keep the other stuff turned off.
I usually bring in tomatoes that are advertised as patio/container suitable while they still have flowers and green tomatoes on them-so I get a decent return.
The pepper plants were great though. They just bloomed and produced, and bloomed and produced all winter long. I had them in tiny pots, so they weren’t really big, but just right to add to a salad or add to other veggies in a stir fry.
