Hundreds of companies offer commercially made hydroponic systems that can have you growing successfully in no time at all. These systems are easy to setup and easy to use. The drawback to using these systems is that they can be very expensive. A small setup for 6-8 plants will cost you over $200 and that does not include the lighting which will be required when growing indoors.
An alternative is to make your own hydroponic system. There are thousands of free plans available on the Internet to construct just about any hydroponic setup you can imagine from large outdoor systems to compact indoor systems designed to fit on a window sill.
If money is not an object in your preparing plans, consider purchasing the necessary equipment from your local hydroponics store. Although expensive, you will save loads of time and be gardening more quickly than you can imagine.
Explain to the employees at the hydroponics store what your goals are and they will be able to direct you to the best equipment for the job. Make sure you know what kind of produce you will be growing and approximately how many plants you will be starting before going to the store. This information is integral to making an informed decision about hydroponic equipment.
The more affordable route is to build your own system especially when you are just starting out. There are many ways to build hydroponic systems at home for pennies compared to the cost of purchasing the same equipment.
