The ebb and flow hydroponic system (also called flood and drain) is the classic hydroponic setup. It is easy to understand, build and maintain. It's versatile and can accommodate pots of any size, or even rockwool blocks. We love the ebb and flow and use it often.
Individual potted plants are arranged on a drain table or "growing bed" which can hold a few inches of water. Periodically, nutrient solution is pumped in, flooding the holding bed. The plants are watered from the bottom through the drain holes in the pots.
After a few minutes of
soaking, the pump cuts off, and the table drains, the nutrient
returning to the reservoir below it. This flood-and-drain cycle repeats
2-4 times a day. Simple but very effective.
There is a link at the end of the project series to a nice printable booklet of the process!

Not into Do-It-Yourself? Perhaps one of these complete kits is perfect for you: Hydrofarm's Megarden Systen or the Big Boy Bucket System.
This is a great, dependable little unit. You can grow four- 6” to 8” pots or several smaller plants. It costs about $90 (not including a lamp and food). Most of the materials are available from Home Depot or Walmart. A few items must come from a hydroponics supplier (but we give you a good cheap source).
