Ever since I saw product demo video by a company called O2 Grow, I've been interested in alternate methods of aeration. The O2 Grow product is just ridiculously priced so I looked for alternatives and a found the Venturi method. I had a spare 250gph pump that came with a venturi kit, so I put it in the control bucket of my RDWC system, and tbh it works pretty good. It spits out a lot more smaller bubbles compared to the air stones and the pump really churns up the water making the bubbles stay below the surface for much longer. But there are other versions of venturi that use a higher pressure water pump (around 50 psi) to create micro bubbles that turn the water milky because the bubbles don't really rise to the surface. Is this overkill? I mean when it comes to hydroponics the more dissolved oxygen the better right? What are your thoughts?
Anyone use a Venturi injector for aeration?

I agree. Venturi is where it's at. Dissolved oxygen happens at the surface where the air and water meet. Not in the water. Agitation of the surface is what you want.

You would use a separate reservoir. It's used in RDWC not single site buckets.

Thats y i said i want to figure it out. Dont want a separate bucket i dont do dwc anymore but will do a run or 2 again just for fun. But even then I'll run a single or double 10 gallon tote and that will fill my 4x2 tent completely out.

If you end up using something like these 17gal home depot yellow lid totes you see on here all the time, you could probably put a pump right in with it no problem. Use a mesh filter bag to help to keep roots from growing right into it.

No one might see this but I'll comment anyway. I designed a rdwc system using venturi pvc tees and it works perfectly. Search "rdwc with no air stones" on Reddit.
Just going to have a look but check out my new thread on here will ha please @DarkChild758
