pH in Hydroponics: Explained

[@lorettastinnett6848]

Awesome video, that was the most comprehensive explanation I have heard yet. Great job.

[@trishapomeroy9251]

That was awesome! I look forward to seeing the next installment. I have a constant battle with keeping my pH low enough.

[@jaylodewijckx2898]

try using a lower ph water to start with like rain water or ro water

[@charlesdeuter]

Amend your nutrient solution with ammonium sulfate! It's a cation so it's absorbtion will make the pH drift lower. This is especially important when doing kratky method.

[@mateuszgezakowski5442]

It's also worth mentioning that CO2 from atmosphere can dissolve in water when it's sitting over long periods of time like in hydroponics setups CO2 then reacts with water and forms carbonic acid H2CO3 which is soulable in water and dissociates to H+ and CO3 2- and some more chemistry happens, but keeping it brief over long periods of time that can bring down ph. That's the reason why in chemistry labs all solutions must be kept sealed.

Many thanks Mitch. I've saved this to my YT play lists. +1!

Do one for nutrients please

[@djredhareaus38]

Ok but should I add ph down before or after i mix the nutrients and dose it really matter what order i put in the nitro cal

[@rmcnasty7319]

Good Video Hooch👍 In what order do I add nutrients first ?

[@kjoemack7013]

excellent. great layman's explainer. more please

[@lindacouture3915]

really interesting, I always knew that pH and electric charges were closely related without knowing exactly why, thanks !

[@antoniosanford4675]

This is quality content. Can you do a video on dosing hydroponics systems with nutrients and Venturi mixers and the doseatron?

[@gutrali]

It should be mentioned that full-time pH and EC measuring devices still need to be cleaned at least monthly I find. They should be calibrated as well since they can drift as much as any other sensor.

[@geoffmastus6136]

Thanks for this one…I’m still struggling with how temperature affects PH even to the point of calibrating my PH meter.

[@michellecolledge2355]

I needed this video. Thank you.

[@SinnerByAnyOtherName]

Great video. Just of note/interest - the pH can be below 0 or above 14.

[@TheCassenator]

No, this wasn’t too intense. Some people don’t like purely educational content, but this is the kind of stuff you need to know to be able to do hydroponics. With all the content that you have, you should put together some kinda guide like Rob Bob did for people who feel overwhelmed and don’t know how to get started.

[@downunderfulla6001]

I’m fine with ph but ec makes me confused

[@TheHayruss]

Does the scale or range of pH to ion exchange in plants differ between soil based vs water based grow methods?

[@paulveenings6861]

Why does my ph drift, mostly down, in my nutrient primary holding tank. This tank supplies several different tanks which require different micronutrients. I keep the water temperature as close as possible to 25deg C in all tanks. 🙂

[@paulburke2000]

Is there an update for the purchase of the Hooch Multi Buckets?

[@pesai5695]

is it okay to supply EC up to 2.9...i thought usually people just use up to 2.0

Great vid as always! If you haven't already found him I'd check out some of Daniel's video's from Science in Hydroponics. He's got so much great in depth information on pH and everything else hydro, if you're anything like me you'll be binge watching them!

[@stephenmarch3736]

It's great to get a dose of the theory, but I am not going to lie to you - I was very distracted by the vertical hooch buckets and the mason jar siphon sneak peek :)

[@MARTINREN1231]

I know will most likely kill my lettuce seedlings but i tried something which will most likely fail. Since i ran out of the hydroponic solutions, i tried mixing together some 14 14 14 fertilizer (the slow release type) and some humic acid. I managed to dissolve it and tested the PH(its at 6). Its on an isolated jar kratky setup so its not that painful if it fails. my current mix is 1L of water, 1/8 tsp of 14 14 14 fertilizer and a pinch of humic acid. i might do more mixture variations just to see if any will survive. or even work. well, if it does, its a cheaper mix with untested results lol

[@D-Grows]

Ooh cool little sneak peak that Hydroland is going to sell the Campbell's nutes in small packs! Hopefully with their buying power prices will be decent 😁

[@gazorbpazorbian]

love this video, but I have a doubt, suppose that you have water with a ph of 6 and also mixed with a+b solution, which I suppose it would have ALL the minerals like phosphorus and nitrogen and what not, so as I understand, if the PH get high, some of this minerals will be hard to be consumed, but what if you use top down to lower the ph? would the nutrients that weren't available be available again?

[@mmmsshenanigans9422]

I am curious about this as well. Hopefully we get an answer

[@Hoocho]

It’s my understanding that over time as the nutrients become unavailable they literally fall out of solution. The longer the time at a specific pH the worse it becomes. Also some elements are chelated, which means they are essentially bonded to a metal to make soluble. Once these react in solution they cannot redissolve. If anyone has greater knowledge please chime in.

[@Hoocho]

Essentially yes, you can adjust your nutrient to make the dissolved nutrients available again. But the longer it remains outside the ideal ph the more precipitation of nutrients will occur.

[@dirty_haute]

As long as the nutes stay in solution, yes it would be fine. But as hoochos said, once they fall out, that's it. It's because the calcium and magnesium reacts with them forming a non solid precipitate (chelated). But as far as drift on the plant itself, the transport pathways through the cell membrane use a sodium (or calcium? I forget) pump to increase the concentration of the nutes inside the cell vs the surrounding solution. These pumps can only create a fixed differential on ion concentration between the inside and outside of the cell. So if the solution concentration of H+ is too high, then it it makes it harder to pull + charges metal ions like potassium, if the OH- concentration is too high is makes it too hard to pull - ions like nitrogen. I like to use the analogy of a car going up a hill. At ph 5.5 the slope is decent but doable, the amount of work the car is doing to get up the hill is reasonable, just the the amount of work the sodium pump has to do to raise the concentration of + ions inside the cell. But lowering the pH to 3, then the hill becomes a cliff. Since at ph 3 there is such a giant about of H+ ions floating around, it's impossible for the pump to overcome them. So the cars rolls backwards and water flows out of the cell.

[@ericacarter8194]

When the nutrients precipitate, are they harmful or inert? Wouldn’t the EC be lower, which can be corrected by adding more nutrients? Better not to get in this cycle in the first place, but also would be good to learn how to get back on track. Looking forward to Part 2!
