I used a new bag of "Black Gold" organic potting soil. It has the little white thing in it too. I do save the contents of the bags of my better teas after it's dried, so I can mix that in if need be. Might be a good idea to do so.

Fertilizer is another issue. Potting soil doesn't usually have enough nutrients for continued rapid growth. There are organic type liquid fertilizers available.

NASA studies I've seen have even embedded their LEDs inside the plant canopy to maximise use of the power available. You could also try adding a reflective material around them. Basil ideally needs about 6 to 8 hours of bright sunlight per day.

It might help to get some cardboard, put foil on it and surround your plants to act like mirrors so the plants can get more sun.
Also on your food scrap plants try to get them to turn green and growing before putting in soil. Be sure to change the water every day so they have fresh water. But don't let the water be too deep.
Have you thought about doing sprouts or microgreens? I do sprouts in the winter when I can't grow outside. I use dry beans from the grocery store. They have to be cooked so I put them in soup. I have not done microgreens.

I like the idea of reflectors to maximize the use of already available light. Just remember to use actual mirrors (which may turn up cheap at resale shops) or flat white surfaces.

Here is a link to an inexpensive grow light set up using Christmas lights. This is the season for after-christmas sales, so I thought this might be of use. You could set your starts in this at night, so you don't miss any natural sunlight.
Also, I second the microgreens suggestion. They are mostly sprouts that have been allowed to green up some, and so take less sunlight than full grown plants. I've used lentils from the grocery store to make sprouts, too.
The government thinks you are too stupid to make your own lightbulb choices. But this tiny ad thinks you are smart:
