There’s quite a few to choose from, price will be a deciding factor. Gaia green is good but a little pricey, roots organic more affordable and about the same result, they just require amending the soil, vs what a lot new growers use which is Fox Farm Ocean Forest. Nutrients are already in the soil, you just water and that’s it. If indoor is your desired method, I would get a light, among other things. Since the sun is your source of energy, why not just put the plant outside, that way it can take full advantage of the sun. If you aren’t really worried about the size of the plant, the pot you are in right now is ok. But if you want more weight, I would suggest upping the pot size to at least a 3 gal minimum.
