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
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', 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!
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!
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!
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)

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

sorry man not trying to hijack
just trying to share some useful nft info
digging the thread =)
I knew that I would have to get a lot of water flowing past those roots
how much flow
like a fast running stream??
what size pumps for the flow
thanks for sharing all the good info man
