EBB AND FLOW
Ebb & Flow: How it Works
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
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.

How to Build a Small DIY
Ebb and Flow Hydroponic System
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).
