So far here's what I have in the build:

Chiller - 400
Pumps - 150
PVC and misc - 90
Sprayers, grommets, hose, connectors, pots, inserts - 150
(2) 45 gallon res - 60
RO system - 150
AN nutes - 120
Miscellaneous yet to come - 100
Meters - 180

I'll have just right at 1400 in this project.

Like Earl asked.... "How fast can you afford to grow?"

hope that helps

Loud...definite + rep for you. Thank you so much for sharing. Please check out my pics of the bathroom I'm using and give me your thoughts as to how you'd set up a res if it were your space. Obv I'll have the unit under the sink right?

What are my options for a res? If it's going to feed my other res it'll have to be by gravity right? So I'm thinking of placing a 30 gal res on the sinktop and have it feed my other res, then pump it back through to drain in the tub with a pump when it's time to change the res... or is there some other way to set it up? If I seem clueless it's because I am. Slowly though, I am learning. Thanks so much for your help.

(18 different) 1/4" hoses running out of the res to the pot sites. The sprayers will be positioned 2 1/2 inches on either side of the net pots. This gives you all an idea of how it will set up. It mimics Earls 4" design. The return from the chiller will act as a waterfall. I can't wait to get this soil grow over with so I can move on to this......

wait wait

its not that you sound clueless, its just i AM STONED

lol i've tried to read that 3 times and my stoned ass is having a hard time.

it sounds as so you are making it difficult for yourself....

why do you want to have the main res on a gravity feed?

i would think thas a bad idea incase it would leak or your plants drink too much and then the gravity feed/float valve kicks in and ruins your pH or ppms just because you had it interlinked

but i dont know, im kinda stoned, ill reread and get back to you.

tell me exactly what you wanna do and ill figure something out

sorry bro

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.

i would just put a pump (of course with a long poly tube) in the RO res and plug it in when you want to fill the main res

Why would I need a pump if it is located above the main res? Gravity should do the work shouldnt it?

Say goodbye to my last soil grow ever.....

I suggest you have two float valves

One for the RO rez.

And another float valve

for the nutrient rez.

I agree Earl. There will be float valves in both res'.
