Which would produce more DO in a DWC?

LOL! "4 screens"! Someone may need a little more practice at scrogging than myself :lol:
It wasn't a scrog so much as a very tall sog, supported by screens. I think the purpose of no branches was the idea that water, nutrients and hormones are best delivered along the apical meristem. I think his idea was you get the most AAA prime tops this way, and less larf/smalls, even if the net yield is smaller. This was done by one of the top(quality, not yield) commercial growers in my state.

Small bubbles can also get stuck/cling to the roots easier, and gaseous oxygen is of no use to roots. It has to be dissolved. Not saying you can't have healthy roots with small bubbles, just postulating the idea that large ones may, at least in some ways, be better. Airstones restrict the volume of airflow in any case. Easier maintenance with open hose, too.
First.. 02 IS A GAS... And once again info pulled from a Butt and NOT washed B4 sharing. https://www.acniti.com/technology/different-bubbles-sizes-and-why-it-matters-to-the-properties/

It sounds like an experiment :). Do you remember the yield? I bet he had some interesting results. I imagine the distance water had to travel up the stock had a negative effect on the growth. But that's just a theory.

I turned up the fans and moved the light closer, to about 14". Can anyone tell me how deep my 600 watt HPS penetrates the canopy?

I'm debating trimming off some of the old, large leaves, but I'm in week-4. Early on I cleaned up a bunch, so I'm able to see through the canopy (barely).

Opinions?

If it's super bushy by all means. Most pruning should be done by week 3 but you can always defoliate here and there to maintain some sort of uniformity.

Should have done that B4 the new addition.
No biggie. I've got room to work, and I'm 6'3" so I've got long arms. I may be a dork, a nerd, and a dweeb, but I'm tall, and that's something!

Now everyone, golf clap :clap::clap::clap: LOL!

I actually did defoliate the first week of flower. The canopy was pretty thin, and I was concerned about how much was going to grow after that. But everything filled out nicely during stretch.

I started trimming from the bottom, but there are so many buds that it's hard to work around them. Doing anything from the top always results in my bopping some buds on the head by accident LOL! I think I'm just going to leave them alone to do their thing.
