Which would produce more DO in a DWC?

Towers o' Flowers :)
The smell is so thick that I could bottle it up and sell it as Hot Sauce! :)









Even with the weight of the colas, I still have to keep the branches anchored, so they wont reach the hood.


It's pretty dense in there

They are hard to find, luckily I have some therefore I have the name of them which is Nie-Co-Rol a Dutch product, here are some US links where you can buy them mate...

Mind you they are actually pretty expensive in the US, so here is a link to Pflanzburg a German vendor that also send to the US.

Does anyone know the actual gallons this 27-gallon tote holds? I'm trying to guess the number of gallons for my nutes/pH. Is there a way to determine the number of gallons, besides the obvious "pour n-gallon containers of water one at a time and mark the levels"?
If your still wanting to know how to calculate h20 volume per your container..take total volume % container height =
Then you take container height minus netpot height or water level height=...
Then you take that last number x by the 1st so like the 27gal containers with 8" net pots
Gal 27. Height 15" 27%15=1.8gal per inch
Net pot 8" is 5.5" container 15 so 15-5.5=9.5
9.5x 1.8=17.1gallons...and depending on size of pvc 2 or 3" it's about 10% add and theres your water level the measuring tape too is a good idea if it's a absolute must....I never really go by gallons on nutes anyways since everyone is so half ass backwards on how much too use company wise..I go by ppm and p.h and has done just fine for me esp with rdwc


I'm thinking that the 2" pipes and 3 of these totes, filled to that level, would be around 80 gallons. Around the third week of veg, I usually drop the level around mid-way.

Dabhead710, yes they might be a tad expensive at 1.10 dollar a piece, but they can be used for years and they are in my experience better and much more flexible and adjustable than a net, not that a net or two isnt good...

Instead of buying hundreds of yoyos and them being everywhere why dont you do a adjustable layered scrog net 2 or 3 layers and problem solved very easily.....View attachment 4320646

That's a great net you built. Mine is a little more simple, in that, I have my pvc ziptied to the posts, directly. The frame adjusts up and down very easily. I do sometimes put up my second net, but I waited a bit too long, and ran out of space. I usually use the second net to support the buds. But these branches are still pulling the hell out of the net, trying to reach the light. They aren't having any issues supporting those buds :)

One thing I try to do, is salvage my net, so I don't have to keep stringing it up. It takes a little more work pulling the branches through, but worth it. Is that what you do?

Idk why everyone thinks the diy actual true scrog nets not a fuckn trellis netting big diff....same with the growing styles like scrog is with super cropping lst manifold or mainlined or topped a few times...anyways the nets are not a 1 time use I re use mine all the time and get several grows out of a net before I have to restring it which takes a few min you just have to use the correct string and do it right...as you see my scrog I didnt use screws they suck and it's easier to just keep drilling the hole all the way thru and there you go you dont have to have ur clothes get caught on the screws all the time or hair etc plus the squares are straighter it's a tighter fit and 10000x cleaner too...and I can do several levels too depends on strain and lighting etc too

Yes I pull the branches in from the middle usually and then thread them out too so as they stretch u just keep weaving them out til ur even canopy...also with the scrogs as the top net is pretty much for keeping the buds upright from the weight thats aboot it and also they have plant yoyos that has 2 hooks ea which would be better but still fuck that plus not everyone can reach the back of their area to do yo yos but it's nothing to slide some pvc into place...I also found a new attachment method for the 2nd net instead of using screws or dowels etc I got these push in pins that has one that goes on the outside and it secures the pin that goes thru they are nice and super easy to remove or adjust. However with the fully adjustable scrogs u HAVE TO USE 3/4 pvc 1/2 does NOT WORK...as u have to have the crosses that will slide into the uprights and the 1" cross to 3/4 pvc works 1/2 with 3/4 cross wont slide thru the pvc......and using braided Mason line and cut with a flame only.......it will last forever and it will not fray either they have it at home depot lowes etc...just dont get the twisted then you will be replacing also wats nice about the scrogs is I can chop the plant down and flip it upside down still in the net or I can cut the limbs off

Big Beautiful Buds! These are frickin' heavy! Some of the branches are pushing 3ft, with another foot below the net with some decent smaller buds still to trim!

I'm going to have to grow these again, but with a better plan. I know I could've harvested quite a bit more, with a little more attention.

Looks good mate, maybe a tip on trimming, I know to each their own, but I have always found it nice to trim all the small buds first hence they are the most tiresome to trim, which then leaves me with only the big buds to trim and they are always fast and easy to trim. A nice way to end ones trim cycle...

At one point while doing DWC I got sick of air-pumps and air-stones and remembered a test a guy who owned a o2 meter did with all the "common" type of air-stones they had. What he found was the highest D.O. was when he poured the water into the bucket. So I used a small water pump and some tubing so that the water was constantly getting poured into the rez. It worked wonderfully. Was actually pretty silent too.

Yep, that's called a "waterfall", and is one of the components of an "Undercurrent" DWC. I'm pretty sure it was @rkymtnman who did the DO comparisons. But the waterfall by itself isn't enough to provide DO to the center of the root balls, once the roots get really dense. This is especially true for the plants at the end of the chain, where the current is the weakest. Even though the water may have plenty of dissolved oxygen, the roots can still drown or rot. So, along with the waterfall, you need to have a water pump powerful enough to circulate the total number of gallons in the system, 12 times/hr.

My pump is only powerful enough to circulate the water about half the amount. I could get a larger pump, but the reason I haven't is because larger pumps are going to add more heat to your water, which you want to keep below 70. I also like having redundancy. If either the water pump, or the air pump fails, the other will keep things going until I replace the broken component. Yes, I could just keep a spare water pump on hand, but DWC is very unforgiving. If the water pump were to go out during the night, the roots can drown in the hours it would take to notice the issue. One of the other advantages to using an air pump, either alone, or to supplement the waterfall, is that the DO being delivered to the roots is the same at the last plant, as the first.

I'm able to suppress all the air pump noise to virtually nothing, using dense foam sound isolation corner blocks, and by hanging the pump from ceiling hooks, which prevents any low frequency vibrations in the walls.
