If food from indoor farms had any flavor they could “fine tune” it. All we can get here now are tomatoes from indoor farms, you might as well eat the packaging.
They lack the minerals that are in soil.
After a few years the minerals are also depleted from soil
You have to add rock dust and/or Jersey Greensand to get provide the minerals and get the flavor.
This could be done in hydroponics be either perhaps adding it to the nutrient mix or to the growing media.
Any fine rock dust from a granite quarry or gravel pit that has granite rock from stone crusher will do.
I don't know about other rocks.
Try it in your own garden, it makes carrots, tomatoes, beets, etc., much sweeter.
