Is it ok to use garden soil with it or only bulb fiber can be used?
What Kind of Soil Do I Need to Use in Growing Indoor Daffodils?

You can use any growing medium that is light, like potting soil, peat moss or the bulb fiber.
I would not recommend using true garden soil from your garden as it is rather heavy and will compact in the container. This will make it hard for the bulbs to grow roots well, which means the whole plant will not grow as well.
