I grew plants for years in a tank with plain gravel, no fertilisers except fish poop, and an old style flourescent strip. It was a nice tank, too. And happy fish.
So yes, 🙂 you can definitely grow plants in a tank with ordinary substrate and that light. But only really tough ones will do well.
But (as with most things) a little extra money, and care, will reap huge benefits. A few drops of fertiliser and a bit more $ and you could have magnificent plants. But I recommend slow growing ones or they will swamp a 3 g very quickly.
