Flooded Tubes vs Undercurrent

[waterdawg]

I know you said you weren't interested in ebb and flo but i have built a system and tweeked it over the last year and think i have solved the flood issues but never say never lol. It is basically a flood and drain system that recircs 24/7 with upper 6" deep tray and lower 130L res. i have a drain at 4" high so a constant water level of 4" also there is a overflow drain off of the side of each tray 1" below the top. If the primary drain becomes clogged the water runs out the overflow. I have no airstones and the waterfall effect as well as floomers on pump discharge nozzles add oxygen. Each tray is appr 2x4 with 6 plants each. Each system is less than $125.00 to build and very simple to maintain. I have ran the trays through appr 8 runs with no issues but i do clean out the primary drain once halfway through a run depending on strain! Good luck with what ever you decide!

My goal is to set up an automated recirculating system that doesn't leak and has a low probability of flooding my closet. I love the idea of lining the room with pond liner to contain a flood. I have been thinking about the ideal design for my setup, which needs to be simple and stealth. The flower closet will most likely run off one 15A 120V circuit with two 400w HIDs. I will have a small mom/clone/veg area in another room on a different circuit with a 250w MH, so I plan to veg rooted clones and seedlings about 2 weeks which I have found produces around 2' 6" - 3' plants for me. Plenty of room for 12 plants in flower.

My ideal system would be ucdwc, but I still haven't figured out a good alternative to 2" pvc and uniseals.

DFT with 4" - 6" pvc would be just as well, but I am not sure how I would set up the pipes and plumbing. Seems like it would have to zig-zag in a downward slope or something.

I don't think I am interested in any other methods right now such as ebb and flow, nft, aero, etc.

just to reiterate & emphasize: round PVC pipes for a NFT system (or whatever we want to call it) has been known to have flow/pooling issues (I can't recall all of them)....I would likewise recommend something square (like gutter) over a round geometry.... Also, I sorta/kinda disagree that root size is limited in a NFT (not disagreeing, but this could be a "Relative" thing)....my limited experience with cannabis (using real "commercial" purchased NFT shit) was that the root mass eventually found its way to the sump about 10ft away (that's through 6ft trays and about 4 ft of tube) ...just saying I'd pay attention to the design with roots clogging, pooling, et et ...

Oh and here's the girls at 25 days flower, they were vegged for 15 days from seed .

I really don't care what kind of grief I get for suggesting this, and especially whatever grief I get for how old this thread is. I have to say your plant looks like it's foxtailing, and that is a tell tale sign of some gibberellin going on. So, was there some added gibberellin? I haven't used it or other growth hormones, though I do use Jasmonic Acid... Not a growth hormone, it's natural, and it's about plant defense. Yes, it increases trichs supposedly. Though, I only see some difference maybe none. Anyway about it, I wasn't trying to call you out, but to ask you what your using to make your buds so enormous. I believe strain has much to do with potential but the grower also has much to do with that too.

NFT works very well with larger plants but this is system design dependent
many of the tube/pipe systems are designed for small plants and have very narrow channels

the NFT tray/multiduct systems would be better than the pipe systems for large plants
and generally better overall
as the water will run along a much wider flat shallow channeled surface it has a much larger surface area to spread roots out
also being flat the channel will stay shallow .5cm or less deep the groves cut within the bottom of the channel ensure water can flow under roots
without creating puddles

dwc can grow large plants too, although NFT will get them bigger imo
dwc will work well with small plants sog

This haze plant below grown in a 20 liter NFT tray yielded 21.5 oz (600g)
it was 7 ft wide 5ft high needed 3x 600w to cover it

peace

No, nothing was used other than nutes (vitalink max)
i do not believe in using additives , i like to keep it simple

that plant is not that unique, if you search for mango haze you should find similar traits
on the same run, a sister of this plant only yielded 3 oz and did not foxtail at all she was more like the nordle(afghan) in the cross

fox tailing can happen for different reasons, in this case its genetics
that plant had 3x 600w of light at one stage so it was not lack of light either
