What I meant was that the RO res will be in the bathroom and it will have to feed the nute res in the flower room. The RO res in the bathroom will be on top of the sink so it will be higher than the nute res in the flower room. The RO res will then feed the nute res through the wall via gravity through the float valve, correct? Told you guys I wasnt a damn plumber.....lol

Plus, I'm stoned too.
