Thanks on all the advice.

I actually have a seperate hanna ph champ and a serpate tds/ec pen. I also purchased a complete RO system stage 5 i think. My city water has a ppm of 60 and the ec says 114(if i read EC right). Im debating if I should take the RO system back and just use tap water.

Any suggestions on my water quality?


As far as the flood tray im not sure how much it holds. The hydroponic store i got it from was helpful but not very giving on information specifics. I know its 22" x 22" x 7" and the res is 20 gallons.

I got some 5 in net cups and hydroton rocks im going to put in tonight.
