    Loop manifolds for air line

    I think you talking about creating a buffer system between a weak acid and a weak alkali, they used a lot in biology experiments. I have quite a bit of alkalinity in my water already you see, my pH is like 9. something. I have never had this problem before because I used ghe wich contains lots...

    Here's my ratios for veg mix: NH4 = 2.8ppm NO3 = 30.8 + 5.6 + 10.5 = 46.9 = 50totN (5.6%NH4) P = 15.5 + 1.55 = 17ppm K = 19.5 + 29.25 = 49ppm Ca = 40ppm Mg = 12 + 4.8 = 16ppm S = 16ppm Total: 188 ppm N—P—K = 3—1—3 K—Ca—Mg = 3—3—1 My flower mix: NH4 = 2.8 NO3 = 30.8 + 5.6 + 21 = 57.4 =...

    Loop manifolds for air line

    Phosphoric acid works well and is cheap and widely availible, but I already added like 30ppm P from MKP and an extra 0.05 mili-molar units of phosphoric acid will bring it up to 34ppm actual P. So I don't want to go further into "the luxury range" as too much P causes problems. I have 60ppm of N...

    But potassium bircarb is alkali, I'm having problems keeping it down

    Loop manifolds for air line

    My tap water is very clean, only like 50ppm. It's also very alkali so I use acids mainly to keep the pH in check. Do you guys know the NPK Ca Mg S ratios your're using? Because I make my own, setting the ppm targets for individual nutrients is important, and takes much trial and error.

    Does anyone have 'optimal' nutrient ppm levels for undercurrent/rdwc?

    Loop manifolds for air line

    I've actually noticed that my pH is struggling to stay below 6....sits at 7 after a few days. Have to add water and nutes 2x a week in this buckets lol, see why totes is more practical there. Gonna formulate sulfuric acid into my stock solutions. That should add some protons to the MKP buffer...

    Loop manifolds for air line

    Nah they pool pump grommets, not uniseal. Also my smaller 1inch ones are a local irrigation co ones which work. Good thing my buckets are floppy under eminence pressure when pushing a pipe thru it. Tho as the plastic ages we'll see. Bulkheads I have had them snap and leak, they far more finicky...

    Loop manifolds for air line

    I just got a 4 plant UC system set up (I only have one light so far). Man it was a pain getting those 50mm (2inch) grommets in even with lube. I also noticed my smaller veg undercurrent (much smaller system) had roots going into the connecting pipes, which were only like 1 inch. Got a 30l/hr...

    Loop manifolds for air line

    That's exactly as how I see it, but I compare a ratio of manifold inlet area(s) to the sum of the outlet areas. A loop manifold means I can get away with thinner pipe as 2 pipes raises the volume. I know you get those short aquarium manifolds, but my garden is quite long vs wide, so my 5mm...

    Loop manifolds for air line

    I've never had a problem with pH and air. It's nutrients without sufficient "pH buffer" that cause pH swings. Google how a chemical pH buffer system works, it's magic, it's like a chemical control system. Phosphoric acid and Carbonates work well to keep pH in a non-linear zone. "Surface...

    Loop manifolds for air line

    2 plants per 3ft wide should be enough, seeing that I'm vegging not too long. Basically 4 plants per 600w HPS space although it's LED. Maybe for industrial scale larger totes makes sense, and also then I would have to veg and trim like crazy Airpumps do keep the O2 gradient higher than just...

    Loop manifolds for air line

    They wont be too big, just enough to fill a 8 x 3 ft. Honestly they not 5gal, just realized, I think in metric, so I'm using 8 x 25 l bucket filled to about 20l I figure, about 3/4 way up, that 20l is a max possible value. My buckets are different to ones in the US I figure, because 7gal US =...

    Loop manifolds for air line

    Wow that's awesome! I heard on riu forum that the undercurrent/rdwc crowd here knows much. I also experimented with flooming last year, like just a pump inside a tote with a short vertical spout so it sploshes down. But now I wan't to try undercurrent 8 site in 5gal buckets you gets. So to start...

    Loop manifolds for air line

    I noticed that blower and I thought one can only really use piston type compressors for bubbling water. Yeah less pipe does seem simpler, and also means I can theretically squeeze in between the buckets, but the garden is quite narrow (1m wide max, 3ft) so I can reach over without being in...

    Hey rdwc and UC community. I am building an 8 site undercurrent ie 4 x 2, so my garden is longer than wider. So I thought of running a pipe long the middle with outlets tapped in for each 25l (~5gal) bucket's airline. Something like this between the buckets. Am worried about The tail ends...
