IF EVERYONE COULD HELP ME BETTER UNDERSTAND,HOW THESE SYSTEM WORK AND THE DIFFERENCE IN USING THEM.
THANK YOU VERY MUCH!

I personally use the ebb and grow its less maintenance than the water farm and far less can go wrong. Cons of my system do not fill up that big ass res unless your doing 15 - 20 plants kind of a waste of money from a nutes point of view.Pros... easily expandable, easy cleanup Plants get HUGE in this system and i mean it huge! not much else to say its a great system been using mine going on 2 years...

One is a drip system and the other is basically a flood and drain with individual sites. I've used a single site waterfarm before and switched to flood tables. Too much cleaning, too many moving parts, and too many tubes and wires to get tangled. Wish I could be more help but out of the two, I'd suggest the ebb and grow.

Bump!!
Thanks

Yesterday my ebb and grow was delivered and dry it seems to be a nice system. Before I actually fill mine I going to add a level sight glass, fittings on top for the chiller, and insulate it. Perhaps a shut off to each circuit would be convenient as well. This should be a good experience.
