Gravel is not a suitable growing media, unfortunately. If you are growing hydroponically, then I would try puffed silica stones, or puffed clay pellets. These options are lighter.

Otherwise, I would recommend using the potting soil of your choice, or soil according to the type of plant that you intend to plant.
