pH for Hydroponics 102
Ever wondered why the pH of your hydroponic nutrient solution tends to drift when you recirculate it? And what’s the best way of managing the pH of your nutrient solution so that it’s pH perfect? Following on from our pH for Hydroponics 101, we go deeper into the science and the gadgets to help you stay on top of your grow.
Great Content Man!
Thank You from Russian growers!!!
you are fucking awesome keep up the good work!!!
Then explain why my ppm and ph are both climbing up it was at 349 then next morning it was at 249 then the next day it was at 348
Finally…someone dispels the "let pH drift up…then knock it back down" myth. I remember back when I was 17 or so (yes – I was very much into hydroponic gardening way back then – almost 25 years ago) I would skip regular high school classes and sneak over to the public library across the street and stay for an hour or 4 devouring any crusty book on hydroponics and soilless gardening I could find. Dr. Howard Resh had the best ones. Hoaglands salt fertilizer recipes…Cornell "peat – lite" mixes…raft systems. All kinds of groovy info I implement in some fashion to this day. At anyrate…I distinctly remember about authors saying letting pH drift out of target was definitely not a good thing. I also remember bugging landscape pond shops to order me a particular Little Giant submersible pump that I wanted to build my first closet system. Indoor gardening shops were unheard of in my area back then. Lol. Good times.
Oh man, those was the facts I was missing to understand PH drift, thaaaaanks a lot
Talk slower! There is no need to run your mouth off. It ruins it all.
Pretty sure that was redmans idea lol
very good information…
Hey man im doing dtw and am having ph spikes daily that are quite large any pointers
nice video man, i wish you’d slow down abit on your speech
key-late, cat-ion 😉
I need information on Aquaponics
Not adding chemicals
I live u Everest! No homo! Lol this content is AMAZING!!!!
Pro growers never use PH up or PH down in their nutrient reservoir. Those should only be used for testing the solution seperately.
Why do Americans talk like they are running out of time?
it’s pronounced cat-ion and anne-ions
My pH starts at 6.5 and takes seven days to drift down to about 5.4-5.3. At day seven you change the water. 1 gram per watt, automatic water changes. You never adjust pH unless you are mixing a new batch of res water.
So when the plant converts NO3 into OH- by using the H+ from within the plant, what is used within the plant to convert NH4 into H+?
It’s vacation "vacashun" and cat ion or an ion. All kidding aside, great videos. I use vinegar and sodium bicarbonate solution to adjust pH.
Dude I just want to say you’re a fucking champion!
"cashions"? Is that a Cajun cation? LOL…it’s pronounced CAT-ion and anions are not relatives of onions, they are pronounced AN-ion. Sorry, my biochemistry gene just spasmed and went crazy with that!
Not sure if it was a good vid or not. I couldn’t get past the cajuns or Haitians or whoever killed all the cats.
Your other video says do not add PH up or down direct to solution but this does just that?
Confused ?
You made a mistake at 5:34. You said NO3- is taken up by roots and is converted into NH3. I looked it up and found that NO3- is taken up and reduced to NH4+ by the enzyme nitrate reductase. Or am i mistaken? Do clarify.
Now i find you…..it took you tube a while….but im here now🤣
very good vidjhoes , question please , do you have to keep all ph probes wet meaning hand held are the same ??
My friend, you are the real deal! Great videos with the right combination of science based facts, and a fun to watch tutorial. Rock on!
I thought I remember you suggesting to add pH down FIRST to the reservior? If that’s the case what happens when these pH controllers add pH up/down? Also, is there any difference in adding cal-mag supplements first or last? THANKS again for another great video!
Very informative ! I am facing an issue with ph up from 5.5 to 7.5 in every 4 to 5 hours with a slight raise in TDS level. I am using phosphoric acid as ph down. Thanks for the help. 🙂
also chelate is keylate
thank you, Everest, for making me smarter, no easy task. this video (all your videos, actually) has answered so many questions about my grow!
That’s a great break down for circulation, but it does not explain the same effect in a drain to waist reservoir.
In the 101 video you mention diluting your pH adjuster before adding it to your solution. However, in this video you seem to be adding it straight to the solution through your doser. Are those specific brands already diluted enough to do so or did you just not mention the dilution in this video?
That’s why I stick mine at 5.80PH Still it barely drifts. I let it go for 2 weeks and it drifted .05ph Botanicare PBP nutes.
Hello Everest,
I posted a bunch of comments with questions to your other videos and here is a question about pH.
I made a pH adjusted feeding solution for my seedlings in a measuring cup and there was 1/2 of the cup left from the time I top watered those little Grodan plugs. Two days later I wanted to use the solution again. The pH has risen from 5.5 to 6.7 just on its own. I use General Hydroponics PH DOWN.
It is clear to me that the acid that was dissolved in water simply broke down whether completely or partially. I must say that the PH was lowered by the feeding nutrients first and then I used the pH down.
Is there any pH adjuster on the market that would not break down this fast.
I can understand now why pH in my res water grows faster than my plants :-).
Thanks!
Great info, thank you.
It is pronounced "cat-ion". Not sation or kayshun.
excellent video. i’m getting huge increase in ph over 24 hours by at least 2 points so deffs gonna add some extra part A which has Nitrogen in it.
Hey guys can someone help me out here? Im new to gardening and decided to feed my soil plants with General Hydroponics. For a month I’ve been adjusting the PH BEFORE I add my nutrients to my water. Today for the first time I tested my PH AFTER adding nutrients to my water and got a PH of 4.1!! So I tried adding a bunch of PH-up to try and get it up to a PH of 6. But after using large amounts of PH-up Im still only getting a reading of like 4.3! What the heck is going on???
Brilliant
O:39 "Cajuns" ? Gotta balance out dem der Cajuns!
Jc thank you thank you finally understand this drift
I love you and your videos Everest. THE MAN <3
thanks spot on :O)
CAT…ions. 🙂
At the 3:40 mark you realize this is really just a long ad for a PH meter.
did he say…heavy fruiting annuals?? 😄💨
Nice work….the audio was really weak though. I full volumed the content and when the sign-off came on I nearly blew my speakers.
Lets say tomatoes 😉 yeah thats why thats the sweet spot
i use ph up and canna 2 part nutrients. i always end up with clouds in the solution. i think it might be canna coco b that causes the clouds. how do i try to avoid the clouds? will the plant still be able to uptake some nutrients from this cloudy solution? thanks.
