I have been reading more on the venturi injectors. Looks like they use them in hot tubes and pools but the price is kind of steep. I'm seeing 100 to 200 dollars just for the valve and to top it off it looks like nothing more then a funnel shaped T. At any rate I would could easily incorporate something like this in my grow but I wont if I cant get that venturi injector for under 20 bucks or build something similar.

The way this thing works: The bucket has a pot inside of it with 5/8inch perforations on the bottom only; it fits a perfect seal inside the bucket. See first picture.... Super oxygenated venturi-driven water trickles in from the top through 1/2" tube when my timer kicks in. A venturi is better than an airstone for many reasons, we can get to that later. Also the oxygenated water has to feed in from the top in order for the process to work properly. This creates pressurization inside Rating: 5
