I GOTTA LOSE THE AIR PUMPS! HOW?! Plus my awesome mini DWC :)

Finally finished my manifold. What a nightmare. It looks incredible though. I'm very very happy with it.

I like it A LOT!

I'll look back to see whether you mentioned this, but How are you aerating the rez?

OK I found it on page 2. If possible see if you can add a DIY venturi to the tubing exiting the pump. Basically a smaller tube on a ~ 45* angle inside the outlet tubing injects a ton of air as the water passes by, thereby aerating the flow

Also, I added these to the tote side of my totes. They work

Well I've got 2" pipe so I can't use screens unfortunately but root clogging has never been an issue. Hope it doesn't become one. The res I don't really need to aerate, but on the return from the chiller I suppose I could add a venturi. I'm using them in my smaller setups res.

You're gonna LOVE my tote upgrade I think. The inline pumps will be here anyday. They're the last set of air pumps to get rid of. The answer is venturis. I've already built and tested them. Ita truly incredible how much they aerate. World's more than any air pump could. But submersible pumps create heat and there's no chillers on these small totes obviously. So with this inline setup I've come up with, I think I'll be the first to ever do what I've got planned. Hope to inspire others.

These go inside the bucket. Just an extra step I take, cause you can't have too much aeration.

can't wait to see your grows. Whatcha going with?

Keep in mind my small setup is F & D, though I run 2-3 tents at a time.

I first tried a small ~ 150 gph pump in my 3g rezes, but it heated the solution too much, so I put the pump on a deep cycle timer, along with my recirculating fan set to 3 minutes on and 28 minutes off. Why 28 minutes you ask? To aerate the rez a few minutes before each flood cycle :fire:

Hello folks.

Many of you have probably seen my mini RDWC. It’s still kickin ASS and preps all my vegging clones for flower. BUT I have upgraded the setup and have gone with some short and wide storage containers with netpots in the lids for keeping moms and weeding out males. I just HATE having the air pumps being so noisy all the time, I’m reeeeally sick of them and honestly, I can’t turn away from true hydro. It’s too simplistic and fun to use nothing but water and get these kind of results. But if any of you have any ideas on what kind of remedy to use to keep oxygen in this small area for the rootzones, I’d love to hear your two cents. THANKS!!!

Hey man don’t know if you found a solution but this is what I did with great results. I’m not an artist but you can understand it. Water pumps up into plant buckets where the over flow send water back down cause air to mix with water in big tank below then pumped to plant continuously. Havnt flowered but here’s veg pics. I covered top of buckets with panda paper. Don’t know if it helps ya but def saves me from loud air pumps. Good luck

If you do F & D or RTW, it is totally uneccessary to areate your reservoir.
The moment that water comes out of a tube and get in cpntact with the air, it will have maximum DO.
The only reason why one could use a circulationpump in your reservoir, is to make sure that your water and nutrients are mixed well.
For the rest, no need at all.
Maxium DO is soooooo easy to reach.
Besides that, there is oxygen around your roots when they are not flooded.
If the roots are just damp, they will uptake so much oxygen in gaseous state.
The moment the roots get flooded, the roots will uptake water and oxygen (DO).
And after the drain, enough small waterdrops are around your roots, and also enough oxygen.
Oxygen in gaseous state is hundreds of times more effective, which the roots will uptake because of the film of water around the roots.
