Please Note: This is a brand new system with the exception that the controller is manufacturer refurbished, but it's still guaranteed to perform as a brand new item would. The EBB-12 Ebb & Gro (from 12 to 48+ plants) is the most versatile ebb & flow system on the market. With many growers going from large numbers of small plants to fewer, larger ones, the Ebb & Gro fits the bill! It is a simple system that uses 2 pumps and gravity to flood and drain the planters about 3 or 4 times per day. The fill drain cycles are controlled by the controller unit (the square white container) to control the feeding schedule that you set on it's built-in timer. This system can be set up in many different sizes and shapes to fit your exact growing needs. You can add more grow pots as necessary. It is completely expandable. The EBB-12 system works by connecting all of the grow pots to the controller unit. All necessary tubing and fittings are included with the system. Then you just set the timer to fill and drain the pots about 3 or 4 times a day. When the fill and drain cycle that you set comes on, it turns on the pump in the large reservoir (the 55 gallon drum), and starts filling the controller unit. Since the grow pots are all plumbed to the controller unit, the water in the entire system starts to level off with the controller unit. When the pots are full, and your drain cycle starts, the pump in the controller unit pumps all of the water back into the reservoir. When the level of the water in the controller unit goes down, all of the grow pots levels go down also. Then the controller unit waits for the next fill and drain cycle a few hours later. Each grow pot consists of 2 pots nested inside each other, the inner pot has a lot of holes in the bottom to allow the water to enter the grow medium and the root zone. This will allow you to be able to pick up the inner pot and move the plants from one site to another on the system. This will allow for even plant growth even at the

Update January 2015.
After four separate grows I have learned a bit for my specific use. First, so called "designer" nutrients are a waste of money. Talk with your local hydroponic store operator and buy off the shelf products that he/she might suggest based on what you are growing. They want long time customers and generally will not steer you wrong.
On the subject of nutrient replacement I found that what works best for me is to start with reverse osmosis water filled to the level desired (10 gallon minimum plus about 3 gallons for each pot works for me) and add nutrients as per label instructions or as guided. BTW I always use a couple "air stones" with an aquarium air pump to keep things mixed up and aerated. It does not cause any foam if done properly.
As water is used I wait until it gets to about half then replace with fresh reverse osmosis water only (NO new nutrients added!). That is repeated a second time so that when it again gets down to a very low level and there is barely enough to cycle properly it is time to change the entire water and nutrients out. For me that is about a month early on and maybe three weeks in full bloom. Or once for veg state, two to three times for bloom stage, then plain clear water for flush stage.
I've tried three different media and found the following. Started with coco coir chunks. They work great but are expensive. Advantages are great aeration and some water retention for safety if you leave for a time (I typically can be gone for a couple weeks at a time). Next I tried coco coir fiber. Much cheaper but way too dense. The ebb & gro system is too passive for it to work very well. I do not suggest it at all for my use. Next I tried expanded clay pellets. Much cheaper than anything else with great aeration and root support. The only disadvantage is very little water retention which places a lot of reliance on the integrity of the ebb & gro system if you leave for a period of time (which I now have).
Happy growing and harvesting!
