I think you have medium lighting and should be able to grow a wide variety of plants. There isn't a specific ideal setting for plants. It just really depends on what plants you want to grow and if you're able to find the right balance between light, CO2 and nutrients. Your lighting shouldn't restrict you to low light plants, so you should have a lot of options. If you use EI dosing, then nutrients won't be an issue either. From there, it's just a matter of fine tuning your CO2.
