found exactly what i need at the local shop today, they have everything i could possibly need to get a similar setup to yours, thanks man. I was thinking that with dwc, youve got about, 45 gallons of water to change since solution is contained in each bucket. But, with a drip setup like yours, i can automate the res and not even have to worry about the plants, just let the res self adjust, i wanna get solenoid operated dosers and a controller, that way my res can be whatever i program it to. Gonna wait on this for a bit, gotta get a RO machine up and running first, im tired of buying/carrying distilled water when i can make it myself.
