Have u seen the Mr. Green vid? hes got an ebb n flow sytem and he sets it up step by step. u can find it on this forum, somewhere

go to youtube and type "how to grow green" it comes in seven video sets and the dude is painted green but he does not cover nutrients or ph for that type of setup so come back here, these dudes know their stuff.
and trust me ph is a HUGE FACTOR 5.8-6.2 keep it in this range.

6.5 is perfect ph

Man for a Ebb N Flow setup plants like it slightly more acidic, 5.8-6.0 is ideal
