Growing hydroponically is a big step for many people and can be a huge learning curve. Please do your homework. There is a lot of information online. You can enter "key" words into a search engine, open a new folder in your computer document section and then begin to download (or print) articles that are of interest to you.
When you are ready to begin growing, decide what type and size hydroponic system is most suitable for the plants you wish to cultivate. There is a wide choice of systems…the best decision will be guided by the amount of space you will dedicate, the accessories, the power access, available lighting, etc. Growing hydroponically is more of a science than putting a seed into the ground, but it is easily learned and can be used all year even in colder climates and is extremely space efficient.
We all have to start somewhere so choose one plant, one system, and start growing. Once you are comfortable with your first project, the odds are you will be ready and eager to move on to growing more and different plants. Check my website for a comprehensive plant list. If you are new to hydroponics, my suggestion would be to start with basil in your first system…you will have immediate success…it grows quickly, is a low-growing plant, and there is nothing like fresh basil in your home cooking.
Check out the videos on my website as they were especially produced for the beginning grower and can guide you step-by-step through the process. I have been interested in hydroponics for thirty years, and have engineered my website to make everything as clear and simple as possible, thereby giving you encouragement to begin your first project.
