There are a number of books available in your library or local bookstore that can teach you how to get started in hydroponic gardening. They can give you the basics of the practice as well recommend some products. However, it may be easier for you to learn how to get started in hydroponic gardening from an online community.

In an online hydroponic gardening community, you can have conversations with experienced gardeners and learn from their mistakes and successes. You can learn how to get started in hydroponic gardening from people who have been there, and later on share your experiences with other community members.

If you are more of a hands-on learner, visiting an existing hydroponic farm or even a small-time hydroponic gardener is the best way to learn how to get started in hydroponic gardening. If you find someone who is willing to take you through their setup and share their secrets with you, this can be a great way to learn.

There is really no substitute for seeing the methods and results first-hand. In exchange for the lessons, you might volunteer your time and your hard work to the farmer or gardener in question. They will probably appreciate the help, and you can pick up some valuable practical experience before setting out on your own hydroponic adventure.

In some areas, you may be able to find university or community college classes in how to get started in hydroponic gardening. The horticultural departments at many schools are embracing the "new" hydroponics, and this is the perfect way to learn from a master. Even garden centers are getting in on the action, so if you know of a garden center that uses hydroponic gardening, ask if they offer classes or lessons on the subject.
