I'm so confused. You always put too much information. Your a mad scientist. It looks like the system requires you to completly seal off the plant from the roots. All those layers look like they are creating an air tight seal, is that correct? My second question is more about the venturi's. That is something entirely seperate then the system you designed right? Where did you get those things? Could they be used by themselves in other grows to get better results then air stones?

One more thing, since you seem to be an ebb and flow expert, why do you run your timer every 3 minutes? I just built an E&B setup and was curious about watering times. I was setting the timer to 12 minutes. It only takes 20 seconds to fill my tub and maybe 10 seconds to empty it. I use 3" netpots filled with hydroton and a neoprene collar on top. How often should I set my timer?
Prodaytrader Reviewed by Prodaytrader on . The Suck-it Bucket (NEW) Ok. 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
