well, i dont think any1 special made this ebb and flo system, its pretty generic from a local hydroponics store, does this answer your question or have i misunderstood u?
as for the updates of my plants, most of them are thankfully healthy, while one seems to be pH burnt, and the last pis is apparently a mutent mutent..
the brown 'marks' on the 1st 2 plant pics are from foilar sprayed a few hours ago wit a plant food/growth enhanser and carbonated water mis... not sure if its normal to have that, if not please inform me...
