RDWC return line question

Those return lines look pretty small.....but like it shouldn't matter as long as you have air stones......

I really like sqydros/heath style rdwc better than undercurrent style. That being said, I'm sure both can do well.

It was actually brought up in sqydros Diy build thread by Doer, that pythium loves air stones. I had a pythium problem (well had many lol) caused probably by a few factors, but I blamed my commercial air pump. I can't remember now, but I used my infrared thermometer on the air tube being pumped to the air stones and it was extremely hot. I'm sure this can probably be overcome by rapid flowing water and chiller but just food for thought. I like the simpler design without air stones.

Dissolved oxygen is ......well oxygen in the water, what the roots need.

P.S. Sqydro it looks like from the photos you setup a perfect room? How'd that work for you?

Oh yea, Im not too worried about the air then. I have used the pump with with DWC, just not RDWC, and the plant was massive. but i let it die. itgot some bad root rot, which at the time, was too far in to fix.
and that is why I am doing this RDWC to allow easier control of the temps. because i wont have to risk taking the plants out of the buckets and doing it one by one, which wasnt very fun to try and pick up a plant by the net pot when it was 3 feet tall and a big ass bush. lol

and I plan to use a Chiller to cool the water. When I get it all running with the air stones, ill take some pictures and such for you all, and you guys can share some more ideas to make it better (:

I want to get this down, before i move to anything more complex.
I got Soil down. So now its time for this annd if i like this and get good results ill stay with it, or upgrade (: im sure ill wanna upgrade, we always want something better.

chiller is essential in any DWC imo, to easy to kill em otherwise and its expensive but loosing 50oz of smoke is more expensive lol

Thank you for the pictures!
Yea and I wil be using airstones with a commercial air pump. so im not worried about the water flow keeping air in the system.

and like yours i plan to wrap in the foil tape.

And can you explain the dissolved oxygen to me?
dissolved oxygen is oxygen in your water, it gets there by water fall, airstones, fluming, it takes place at the surface being broken and air exchange takes place, air stones dont put air in your water its the bubbles breaking on the surface and mixing that does

airstoneless DWC FTW imo i done this grow with 1 pump running 4 pots and 0 air stones

Yea, and one day ill maybe change, but I worked hard on this set up, and i feel it will work woth airstones for now, I do need to get a chiller. I dont want rot, that sucked. lol
Nice pictures man.
when i get this set up and going, ill start a journal for y'all

yeah look forward to it mate, some bennificial bacteria in there never hurts to battle the pathogens mate but chiller n u should be fine all the best mate

So i am looking into ways to help prevent root rot.
I know chiller to keep the water cool is the best. but they are a little costy. So Since I am using an Air pump, i'm thinking about making a way to "water cool" it. because those air pumps get hot. And i'm sure the air heats the water up.
what do you guys think?

Hey guys

So i am looking at getting a chiller, I figured idk need 100 BTUs, so im going to get a 2200 one to be on the safe side.


But I am confused... I am goingto use a 10 gallon rez and there is a total of 11 gallons in the control and planet buckets. for about 21 gallons.

So how would I chill both the rez and the Control? Or Is the rez excluded from that because it doesn't need to chill that water until its in the system, right?

I did go ahead and move the res outside of the tent. I'm going to put it next to another 10 gallon that will be used to cool the air from the lights.
I made this out of a oil cooler which i got for free, only cost me about 7 dollars for the vent and a few cuts from the aluminum. lol

I'm waiting for a pump so I can test its cooling. Im looking at sealing the room. so I can introduce C02.
but its almost there once it it ill start a journal for you all (:
Wanna get it perfect.
