Ok, lets compare ebb and grow to a flood and drain system.

They have in common, one water pump and one timer.

Here's a list of the extras the Ebb and Grow has

It uses two water pumps, so:

1. it has an extra water pump
2, it has 2 float valves
3. It has a control board that runs the float valves.

Just those "extras" are FOUR separate things that can go sour. If one of those malfunctions, and you're not in the room for 12 hrs, you could have a dead crop - at least cause a lot of stress on the girls.

It also means you are FOUR TIMES as likely to have a disaster compared to Ebb and Flow. The odds are too expensive, and it has cost me a lot of losses in yield several times, and I am tired of it.

From all the comments and such I have read about this setup it seems the biggest gripe is that the last bucket can end up with stale water. If fact I believe it was Daddy that pointed this out and I think he was the one that mentioned turning it into a drip system. So far here is what I have done.
