DWC bubbles question

I use to run a very large air pump,now I have a small 4 port running in 5 gal pails.Bud growth is noticeably better.Cant prove that its the reason but for sure less air does no harm.View attachment 4811340

Really, the "correct" amount of air is what's needed. Looks like you're within that range. With everything, too little or too much is usually not good.

Why such large netpots? You really only need 3" to 4" for dwc.

Good question! When I started dwc grows years ago I blindly purchased 12 inch net pots, ishould have done more research. That much grow media is totally unnecessary. I typically veg a while (8 weeks) to get big bushes. I am actually in the processing of changing that so I'll use 3 inch net pots and veg only a few weeks. I need more harvests!

So instead of 1 plant per tote I'm shooting for 6

I grow just 2 per tote. I think 6 would get pretty full, unless you were going for a sog/scrog

So can you confirm is that level of turbulence 'not' too much for the roots causing breaking roots? I just got a 20 Watt pump with a 4 manifold for my 13 gallon Single RDWC units. With three small air stones (one for the top drip) I get that rising turbulent spots where the air stone is. I am trying to decide how much turbulence is too much. I suppose I could get bigger airstones which would spread out the turbulence?

Here's a short clip showing the amount of bubbles I have. My yields have always been impressive, so don't be concerned about "too much", work on solving "too little".

I've been doing DWC for 8 years now and never have issues and get big plants quick.. I was just wondering about the bubbles bc sometimes my airstones get caught up in the roots and I don't see many bubbles.

I have heard using paint bucket strainers will keep the roots out of the pipes and airstones.
