Ok… I gotchaHold up don’t get me wrong I know he does get runnoff but not every fertigation. But he does top/hand feed once a week which I’m sure gets some run when he saturates entire pot just when the irrigation is running I believe he shoots for just a little
Some folks on site have gotten incredible results with almost overloading the root zone with air….
Do a search above for “Max O2 dwc” and find the thread with pics of a rootmass that looks like what you want…. It’s just extra air
Ah, ok. I am doing DWC in 5 gallon buckets.
I wonder if the photoperiods I am growing now will get big enough to fill out the bucket like that. I've been looking at different trimming options, and I decided I'm just gonna top them like 3 or 4 times, and feed plenty of silicon so the branches are nice and thick.
I’m pretty sure derek420 ended up using those big flat air stones… tiny bubblesLots of factors and I know very little about dwc. I believe it can have to do with bubble size and how aggressive they are..
Stuff MOG has said about bubbles
It looks to me like your bubbles are too large and therefore also violent. The smaller the bubbles the better. If you look at the root that is still in the moist air, it has a bunch of fine lateral feeder roots that look like fuzz. These are the roots we strive to protect in the water from too much turbulence. The smaller the bubbles the more surface area to exchange oxygen to the water, it is from the water that the roots get the oxygen they need, not from bubbles touching the roots. I always had two stones on separate pumps in each bucket, one pump on a battery backup.
Changing the volume of air did not change the bubble size and that is what we are looking to do. You need better air stones.

Yes, air to the root-zone…. That‘s very important. It makes a HUGE difference. Can’t find any photos on it, but it’s like a frikkin BIG-PLANTS-Turbo!Some folks on site have gotten incredible results with almost overloading the root zone with air….
