    Building another RDWC system for VEG

    In my closed loop chiller system i'm running RO water with a little H2O2 to make sure nothing builds up. My cooling coils are not copper, they are food grade Stainless Steel 304 wort coils connected with black vinyl tubing. I got a coil in both VEG & FLOWER Reservoirs and they work great!

    Building another RDWC system for VEG

With a 400 GPH water pump I'll circulate RO H2O through this closed loop system from an insulated 5 Gallon chiller reservoir to 1/4 HP Active Aqua water...

    I've been revising yet again... Here is my latest design for my 6'x6'x7' flower room: • Moved 2" return & 1" waterfalls closer to the outer wall for more room to maneuver around plants. • I removed the 400GPH water pump. • Added a sample pot for testing pH, EC & water temperature. • Added valves...

    My RDWC Setup. I'd appreciate your input...

    Correct, yes 48 lpm. I used those medium sized air stones but found they put out much bigger air bubbles, so I made my own DIY air diffusers with 50’ of Dramm 1/2” ID soaker tubing with each: 4 - 1/“2” Tees, 1 - 1/2” Cross Tee 1 - 1/2” to 1/4” Reducing Tee

    Thanks for the input, but as for the alita 40 linear air pump... “Underpowered” NO WAY! Uh uh, this pump is a HORSE! I got 1/2” tubing I’m pumping through. TONS of micro bubbles
