A few quick questions about the setup, I'm about to tear down my giant flower room and turn it into a veg/flower room but this time I'm going all hydro, no more dirt!
The self cutting outlet clamp, does this feed directly into the pumps intake?
The pump itself, does it go inside the reservoir, or was it shown outside just as a visual?
You T off from the pump and have a waterfall recirculating inside the reservoir, the other side of the T goes up and out the reservoir, and is then T'd off, to feed the left and right side of the room, correct?
And finally, if the self clamping outlet returns all the water to the res, why are there return lines feeding into the bottom of each side of the reservoir? Is this to mix the solution, for pressure relief? Not sure if I understand that part 100% if it works just as well with or without that part?
I think that's it! I have everything I need besides the fittings and that self cutting clamp outlet thing. Oh, also, your final size of your return lines were 1.5" correct?
Thank you sir!

I didnt feel like dishing out the $ for circle drill bits so I just use a SODERING IRON and make my own, only downside is the smell of plastic melting.
Im using DWC, is RDWC that much more better?

Yeah, unless you work drains in the bottom, each bucket will contain, for me, about 1/2 gal of old solution.
I had a technique where I'd use a tiny pump to dunk in each remains, but that gets old as the root balls grow.
But, I've been reading lately that you really don't want to run them with pure water, for a rinse, but a dilute solution of nutes will be better to rinse the roots. They don't shut down and the will osmosis out the extra salts.
OK<
I pump all out but the reminders and then fill again, overfull. So, I let the TDS run at about 200 over the natural load on the filtered water, so maybe 320 for me. I run that for 1 hr.
Then pump all that out and refill. Now I'm looking at very close to natural load, so no worries. And I did a rinse cycle for the roots.
Then I begin to dose and I dose only in proportion against the TDS meter these days. The marketing will ruin the plants at those dosages. You can end up with 2000 TDS very easily. I want to put various things in first before the GH 3 part. And they all change the pH.
- Cal-Mag
- AquaShield, stabilized for H2O2 environments
- SM-90
- Hrdrozome
- Silica Blast
- H2O2
Adjust pH down with nitric acid. Now I'm at base TDS and there is nitrogen from the acid...about 450 TDS.
Then with a 60 ml syringe, I begin the nute dosing. 10ml, 20ml, 30ml, the 1-2-3 flowering scheduled.
Wait for about 1/2 hr and see the TDS.
I keep that going maybe 3 doses over the next 2 hrs. And I land at 950 TDS.
I only do that 3 times in 60 days, and every 10 days I pump out one half of the pond and bring it to level diluted and then the proportionally dose to target.

Inspiring thread... I'm running a single 3 gal DWC bucket. 2 1/4 gallons up to the netpot. I drain the remaining gallon of nutes the following day and replace with fresh nutes every night. At least I know by doing this my roots are nice and lush lmao 
. but it would be nice to be able to leave it for a few days to go away for a weekend here and there. Having a remote rez seems like something I should look into building. I do have a bottom drain valve on my bucket for easy draining. That I learned from my first DWC gig.. I hated using a freaking hand pump to get all the old water out.

Well, based on my new friend Motul's ideas, I just lowered my top concentration to 450 ppm. I'm hoping the plants will grow faster.
I seem to be getting some nute lock out. The buds are forming but the plants aren't much above 1' tall, after 3 weeks.
But, the main thing is no visible roots. The first 3 times the rooting was very quick, but I think I went too high, too fast. Live and learn and smoke.

Well, I use a little aquarium pump, but i know what you mean. How about PPM? What's your plan?Inspiring thread... I'm running a single 3 gal DWC bucket. 2 1/4 gallons up to the netpot.

Hey check this out. Probably advanced right? A problem if you want to run multiple re-circulating ponds on one chiller, itinit? It might have the hp, but how to manage the heat across different nute and light areas?
Chiller coils and insulated cold tub. I am looking at this to keep 3 different rdwc systems chilled. Just working with 2 coils for now, running tests.
Right now, I have a rooting in pond and a 7 bucket bloom setup with the chiller. I'd like to link them this way. This will be Christmas wrapped with foil bubbles, insulated like the Root Station. Link these two systems. The interesting thing here is the tub water and so, the chiller can be set a bit colder to account for loses. I did one test, just in a bucket of water that chilled the 10 degrees to pond temp of 64 in just a few minutes.

I have experimented with most DWC methods. If I was going to try UC, I would place some kind of dam to break up the nutes to create splash and saturate the air space. I think offsetting the I/O holes would help, too. JMO
I prefer watering from the top down via Hydro Halo Drip Rings with simple gravity drain back to rez. Not using as drip though, I use a 320 gph pump which creates fast stream from the 54 holes per ring

Ah, interesting. Do you have that on a timer? I've tried some top watering. I seem to go too far/too much, as usual. I agree about the flow. I really wonder if I'm getting good mixing in the buckets.
A innovation for this next round will be flow deflectors. I see a synergy and I think I can exploit it. I cut these disks for the net pot holes.
I realized I can cut the center hole to 1/2 inch and slit the disk to the edge. Then I can work the disk onto the undercurrent hose that runs inside the cross tubes. So, on the current flow back, the water encounters the disk just a few mm out from the tube. And since i cut the center hole slightly undersized so it won't travel in the current along the hose, the disk will have a twist in it like a boat prop to add some spin turbulence also.
I have notice the root particles stay in the buckets and don't travel to the pump filter. That is no good. With a tote, I can offset the flow tubes, like you suggest. So, 2 hobbies.

Hmmm....inside the tub with air pots...very cool. How do you re-circulate the drain water from the tub?

Doer, click on my sig to review my thread. All should be answered there, including return to rez. Any questions, feel free to ask me there.
You will also see a youtoob vid there showing the drip rings in action, though with a small drip pump, where I use a more powerful pump to create a spray.
