Grow Light Question

Greetings all. I hope this is the appropriate place to post this if not please let me know.

Me and the Mrs. Have a few plants that we are wanting to move indoors this fall that we’re needing more than the usual window light.

We had tried sprouting a few avocados to see what would happen and now have three small trees in pots out near our garden that are growing pretty well. Our porch is not enclosed so the next thought was our garage (it can get too cold outside where we are at).

We were looking at some lighting recommendations. Amazon seems to have almost too much and I was not sure what would be best for the trees when it came to color, etc. I didn’t know if they had to have A LOT of light (I have seen some people say 5 hrs some say 12) and if it mattered as to the type or style of the grow lights.
