adding an airstone works great and i wouldnt do nft without 1 or 2 in the res ,keeps the nutes fresh and the roots super white 
Brand new system, NFT straight to 12/12, which nutrients?

I like your design man, V-Cool! you dont bother with spreader matt then i presume?
Standard NFT trays run water level at no more than 2mm, hence the Film in NFT, your system is almost semi-deeptrough NFT( at 10mm-certainly not classic NFT). Plants seem to luv it ah, the flow rate & high DO make for good rootzone conditions, where your winning imo!
is your RW sitting on the base of your channels?
Sorry if i missed it but are you on constant flow, or timed interval?
Ive always wanted to Hybridise NFT & DWC by placing airwands in a deeptrough NFT, sure it'd work great with a bit of tweaking! I called that idea 'Bubbleflow'(im sure its been done before), i still wanna give it a go, might have to lose the RW though & go with Hydroton or similar to pull it off. Your system is doing a similar thing really. same with fast flow, i like it brah!
G'Luck!

Constant flow, no spreader mats.. I guess it's kind of a hybrid as you said.. I knew that I would have to get a lot of water flowing past those roots with about 10mm of water to avoid any root rot. So far they look super white and smell like fresh cucumbers, maybe not the best description, but that's what healthy roots smell like to me
(Edit) i get ya, fast flow/DO etc. Aerobic being the word!
whats your channel solution temps & Res temps, are they the same? do you bother with a heater in your Res, i do myself, dont want it going under 68/70f. im asking questions because ive never run deeptrough NFT. in classic NFT with the 2mm sol level if you leave roots pooled in deeper water you can get issues, its a simple adjustment to rectify. Id say your flow, DO2 are compensating for that. Makes me wanna get my Bubbleflow trip on! A deep(ish) rapid of bubbling fizzing solution! i think they'd lov it, your system & look of plants says it would kick it!

This was my last NFT effort using the 424 contained tanks, run very well really, old equipment me n a buddy had a bit of fun with.
I do prefer DWC tbh, but ill always be a avid NFT fan, simplicity.(heater, 600lph airpump, & a Mj pump)

Nice clean setup..
I'm working on getting a 50 mm airduct on every channel, that way I can pull fresh air into the root chamber.. Have you ever tried this?

No, never had the need to adjust air temp in the duct channel myself, whats your thinking? does the channel get hot? in that case great idea! why not, afterall we all chase perfect/optimal conditions & the best environment for our girls!
Yeah im pretty Anul on cleanliness, gotta be done.
Luv ya set-up mate anyway!
G'Luck!
Thanks dude.. I also like a clean inviroment. I probably clean my growroom twice as often as the rest of my house..
I dont think my channels are getting to hot, the water cools them down. I was thinking more in the terms of getting fresh oxygen inthere for the roots.. Or is this completely unnecesary??
unessasary in terms of DO2, not the heat issue though, then id prolly do something about it. DO2 your gonna get from ya water flow & return action, waterfall & airpumped, temp dependant of course. as for airroots in NFT, your running deep so its gonna be a while before you get anything of mass & anything in the way of airroots, idk i dont think it'll matter with your flow, if its cool/temperate in there i dont think it'd matter much either, maybe a breath hole might help. N1
Its different to classic NFT in those terms for sure. new ground to me really. pumping in cool/temperate air, id say dont bother unless issues arise! i think your canopy cover will take care of any channel heat issues anyway!
haha, ill be racking my head over this one now. be sure interested to follow your progress!
If youve got sealed water inlets from ya res & add breath holes to your channel, the action of your waterfall outlet will suck in air, but would that help, mmm, depends on the temps in the lower part of your Cab/room, a fan or 2 set low would fix that up?
The only issue i can see is once the channels fill up with roots, is your flow gonna get restricted enough to decrease aerobic conditions/DO? nothing a lil H2o2 wouldnt fix up, i luv that shit with NFT & the right nutes. the way youve designed it i dont think it'll matter, & flow restriction would be minimal! idk, but will be watching to find out for sure.
just going back to the aqua!,I had a massive argument with a well known UK hydro shop/supplier over using Aqua & H2o2(Oxy+), they said it was compatible & then they changed the info in their catalouge shortly after that argument concerning that issue, backing up my argument! still dont know if i was 100%, but it makes sense with what aqua has in it. maybe OK at low doses idk tbh. you certainly cant run H2o2 with all your canna addys i know they are definately not compatible, Cannazym, Rhizo, Boost etc. Not sure if bleach would be a welcome alternative or not? something to consider maybe.??
Ive never seen a Canna H2o2 product on the market, says it all to me! H2o2 Works great with Substra/Hydro though.
Cheers!

I use H2O2 (17% hydrogen peroxide) from Vitalink with Canna Aqua, Rhizotonic and Cannazym right now.. No problem. I only use ½ strength of H2O2.
Id never do that, ill be very interested to see what progresses, Cannazym aint compatible with H2o2, ask supplier, Canna Rep, i think it might say so on the bottle? Nor the Rhizotonic nor the Boost, trust me i luv H2o2.(PK is fine/compatible))
Put it this way bro, i wouldnt advise runing that regime at all, H2o2 breaks down all organic matter, those addys contain organics, a big big no-no with H2o2 & Hydro ime. half strength or not, especially with Aquaduct type NFT & rootmats etc.
All sorts of shit building up imo, cant b e good, unless you havnt told me something i should know?
(edit) Hydrogarden make Vitalink/& their Oxy+.(British)

So you're saying that H2O2 isn't helping me at all?
I will definately take this into account when mixing a fresh tank of nutrients.. The idea was to prevent any future root rot with H2O2.. But perhaps I should quit using H2O2 until/if any root rot occurs.
haha, now ya talking, lol cool! No it dont mix well with organics bro at all!
Aqua & Canna addys with h2o2, never! as an inbetween cleanse/flush then great, if it has to be(but not with this Canna line/range)!

Nice clean setup..
I'm working on getting a 50 mm airduct on every channel, that way I can pull fresh air into the root chamber.. Have you ever tried this?
med-man leaves open holes on opposite ends of his trays
he says there is a noticeable benefit to getting some fresh air into the tracks
https://www.icmag.com/ic/showpost.php?p=4292599&postcount=80
sorry man not trying to hijack
just trying to share some useful nft info
digging the thread =)
Great info.. He's got it figured out that med-man.. I will definetly try to work the technique into my next crop.. Peace
Rootrot & similar pathogens, Canna have accounted for in their addy line up, Cannazym & Rhizo etc. Thats why(one reason why) you dont see Canna themselves advocating use of things like H2o2(it'll just fk it all up), keep solutions aerobic & at the right temp, & you should get no issues. You dont see H2o2 on their calculator/or product lines for good reason bro!
H2o2 will break down the enzymes/plant extracts in Cannazym rendering it useless, & your just wasting your money. similar goes for the rest of their addys too.
Theres loads of info out there on h2o2, well worth getting it straight, its a strong oxidiser, why its such a good anti bacterial etc.
I could stick up a hunderd links to info but im sure you can find it yourself: http://www.h2o2-4u.com/
I only advise use/regular use of h2o2 with full mineral based nutrition, even then with regular change outs, as it should be in Hydro. Organic hydro is a relitively new ting & H2o2 dont mix at all!
G'Luck!

how much flow
like a fast running stream??
what size pumps for the flow
thanks for sharing all the good info man
I posted a drawing of my system earlier in this thread ^
I use two 2500 liters pr hour pumps, the pumps are pumping water from both ends of the channels. So in total 5000 liters per hour run through my system, the water dept in the channels is about 10 mm or so..
No problem man, I'm trying al the time to learn new stuff myself..
Peace
