Toker Daily Toker, my friend, thank you for your awesome feedback. Don't worry-I'm not going anywhere! I think I found my vocation in life! Lol. Thanks for subbing-much appreciated. Peace and happy growing, Everest.

+Guy Guyer Thanks for taking the time to comment, Guy! It's feedback like yours that really helps the videos to keep coming! I've got so much backed up in my todo list it can be a bit daunting but this sure is a labor of love now-so there's no going back! Thanks again for the positivity. Peace and happy growing, Everest.

Legal in Oregon Thank you my friend. It's a labor of love, that's for sure-something I know you understand. Peace brother.

+eshindi Thanks Eshindi. I hope you're subbed and good luck with your grow!

Thanks Frank.

+Jeremiah Wilson Sounds like you've been 'round the block more than once Jeremiah! ;) I've lost count of the number of times folks talk about pH drift with an esoteric look in their eyes. One particularly over-confident Welshman once swore blind to me that letting your pH drop to 4.0 and then up to 8.0 was the way to go. He was adamant that this was the only way to go. But he was an idiot, obviously, who - when pressed - could not even begin to offer up anything resembling a scientific explanation for his actions. Truth is: This topic goes very deep! Once I have pH 103 revised I will get to grips with this in pH 104 and look at the science of selective ion uptake and how pH actually affects this at the molecular level. Then we can finally put this myth to rest or, at the very least, describe what is happening in less general terms.

Thanks so much Skipper. Much appreciated.

+pogos kuregyan It really is my pleasure Pogos. Any time.

Great, glad you enjoyed it. I will probably make a 103 follow-up video so if you have any questions just shoot.

Thanks Mike.

by the way... what do you think about "Lucas" formula where only Micro and Bloom parts are mixed in 2/4? or what ratio you prefer? gmb 3-2-1 at Veg and 1-2-3 at Bloom. with 2-2-2 at preflower

+Stanion Wuffy Now THAT'S the sort of feedback Everest likes to wake up to. Thank you. Love coming right back at you Stanion. :)

Yes! I blame my immigrant chemistry teacher. :)

we got some hatians and we got some catians in this here bucket... All the chemist's are laughing at you lol After watching the rest of this video I am appalled...chemistry definitely doesn't work in the way you have described.

Definitely loled on that too.

Claudio Mateos Hi Claudio. Thanks for your positive feedback and question. From my standpoint, General Hydroponics is still General Hydroponics: premium quality mineral inputs, tightly batch controlled / consistent, easy to use, versatile, pH stable, and properly and respectfully priced! That's why I have used it for many years. (Put another way, my plants are even less interested in hydroponics industry politics than I am! Heh!) Okay-from a business point of view, General Hydroponics is still General Hydroponics! Sure, it's become part of a larger family tree but I understand that its day-to-day operations are run by the same people-the same researchers work in their greenhouses-the same friendly folks answer the phones when I bug them with queries, the same CEO, and it's the same state-of-the-art factory making the nutes. You're right, Monsanto have no ownership links with Scotts or their subsidiaries, Hawthorn Gardening Group / Hawthorn Hydroponics so that's probably just BS spouted by invidious competitors. I'd add that Scotts are hardly "faceless". Hugely successful, yes, ubiquitous in garden centers, yes, and a publicly listed corporation, sure, but don't forget that it started as a family-run business and some of the descendants of the inventor or Miracle Gro still help to run parts of the company today. Big doesn't necessarily equal bad. I have huge respect for the founder of GH, Mr. Lawrence Brooke, who was pioneering the hydroponics industry back when I was in diapers and has led it ever since. I even had the pleasure of meeting him at a trade show once along with dozens of their awesome sales reps and they are a top class crew. So, awesome products, awesome people. Of course, there are many other nutrient brands out there and all that competition is a good thing, but I think that GH R&D potentially having even deeper pockets can only be a good thing for us growers. If you want to change something, look to our debt-based monetary system which anonymizes dollars and monopolizes credit in the hands of commercial banks. To quote my main man Henry David Thoreau, "There are a thousand hacking at the branches of evil to one who is striking at the root." Let's just be sure that, before swinging our axes, we've picked the right tree! Peace and happy growing, Everest.

+Johndeere Carter yes they need to be kept wet too.

justgivemethetruth Thanks my friend. I appreciate your feedback and support. :) I blame my high school chemistry teacher-he was an amazing guy but a Polish immigrant and it kinda stuck! Lol.

Thanks Haroon.

Thx

Gabriel Engram Thanks Gabriel.

Hi Olga, what is your water source? Are you using hard water with lots of carbonates and bicarbonates? I'd wager that they have neutralized your acid over time.

Hi Everest I use RO water with 0 PPM. My natural water pH is 8+. I always bring it down.

Hi Everest, I have been doing some testing (new to hydro). Here is what's happening: RO water with 0 ppm gets infested from air os something with bacteria when the temperature rises. My water was left on the table with some residual light from the LEC lamp shining on it and got warm. It had enough food from the feeding solution for bacteria to multiply. The bacteria and the temperature rise cause the spike in pH. Since then I learned to control the environment in my reservoir. Watching your videos religiously but when I start doing something there are always hurdles that nobody talks about. If you want to get some interesting feedback, I'd be happy to share (if you wish to provide some place for posting those observations -PM, channel blog, or something) I have done some rockwool experiments and water experiments. My plants are now happy and green, explosive fast growth. Thanks!

Vasa Rastkov Hi Vasa. No I have not used ion exchange resins in my reservoir although I have read a little bit about them. Do you have good things to say about them?

Everest Fernandez Unfortunately no, but it's look like a very interesting and cheap technique. Maybe in one of your next videos you will try it?

Vasa Rastkov Sure-I will see if I can source some Amberlite IRC-50 or something similar and conduct some tests. Thanks for the info!

Thanks my friend.

The clouds are carbonates and bicarbonates precipitating out of your solution due to high localized pH rises-and, as such, they are unavailable to your plants. You should dilute your pH up 100:1 with water first and then use that to adjust your pH.

+Everest Fernandez (Just4Growers) yr the man! honestly, you have helped me alot lately. much appreciated buddy

justgivemethetruth I'm very happy with my auto pH-adjuster. Just don't get lazy with the res change-outs! It cost US$629, or the "non-connect" model (it doesn't send data logs to a computer via WIFI) is $569.

justgivemethetruth you can get ph adjusters that work just as well as blue lab for less . Look around

Everest Fernandez Thanks. This reservoir change out thing is one thing that has me concerned about hydroponics in general. Even though they you save water compared to regular farming/gardening, it seems to me that throwing out the old water is a real waste and it can still be a lot. And by the time you have to throw it out, seems like it is on the edge or being almost toxic ... because of too much salts. What do you do with all that water, and how much does hydroponics really use? Is there really no way to remove to bad stuff so you can continue to use the water. Here in CA water is at a premium now because of drought. The auto pH-adjuster looks like a win to me, even at the price. The more you can automate these systems the better I assume. It is a great idea. I also like the idea of getting data online about performance. I have not done a hydro system myself yet. I tried a small scale aeroponic setup. When I move though I will be trying this out.

justgivemethetruth Hey JGMTT. Properly dealing with spent nutrient solution is a really important topic-one that I intend to devote a video to in future. If you start with high purity (ideally reverse osmosis) water in the first place then the working life of your nutrient solution is increased dramatically. It is the accumulation of micro elements that really dictate the lifespan of a nutrient solution. My advice is to dilute your spent nutrient solution 50 / 50 with tap water and use it to feed your tougher houseplants, lawn (if you have one - unsurprisingly they're not really my thing), or other containerized plants. There's no need to pour it down the drain. Yes, you could-in theory-filter and purify your nutrient solution but it would be a time-consuming and costly process getting rid of all those salts.

Everest Fernandez Thanks for addressing that issue. I don't know if it is solved because what are the long term results of continually adding unknown concentrations of nutrients to ground, lawns or containers ... but at least someone is thinking about it.

+George Grimany Thanks George. All love gladly accepted from my fellow growers!

+David Newton Thanks for your question David. I had concerns about using undiluted pH adjusters with my doser too. After some research I discovered that the amounts of acid pumped into the system by the Bluelab pH doser were so tiny it didn't need pre-dilution, so I used the GH pH down (a blended acid product) undiluted in the doser.

+pogos kuregyan Thanks for your question, Posos. There are three environmental factors that most commonly affect the pH of a nutrient solution (even if it isn't recirculating) - namely: 1. High air temperatures in your grow room. High temperatures favor something called "nitrate influx" in your nutrient solution. A nutrient containing mostly nitrate nitrogen will steadily raise the pH of the solution over time in most cases and vice versa for an ammonium nitrogen dominant nutrient solution. As I said, temperature has a role to play here-high temperatures favor nitrate influx and low temperatures favor ammonium influx. 2. CO2 enrichment-not relevant to your situation but I'll mention it anyway. If an air pump is used to oxygenate a reservoir, then we can expect gaseous C02 to enter the nutrient solution and a percentage of it will form carbonic acid, which will lower pH. This is especially relevant for those enriching their rooms up to 1300 - 1500 PPMs CO2. Nothing to worry about, but worth being aware of. 3. Biological growth in the nutrient solution. Algae will raise the pH: this is because the algae will absorb some of the c02 in the solution. Bacterial and fungal growth in general will lower the pH of the nutrient solution: as part of primary metabolism acids may be excreted lowering the pH. Hope that helps!

Fatsacks Allday probably has to do with the concentration of oxygen atoms in the res, which also have their own unique charge which will affect the pH balance.

Great answer thank you

heres the link to my reference: kzfaq.info/get/bejne/pa1nirGAmtyxY30.html I will be grateful for any clarification. Thanks

Thanks so much for taking the time to comment Shan. It's correct to say that NO3- is converted and there is more than one step in the process: NO3 first has to be converted to NO2 and not directly reduced to NH4+. I hope that, in trying to simplify for a wide audience, I haven't abused the truth in the process! I plan to delve deeper into the pathways and processes surrounding all the primary nutrients in the coming months so stay tuned! Thanks again, peace and happy growing-Everest.

+propertyservices1 PPMs going up is normal, your plants are using more water than nutrients meaning the overall concentration of remaining nutrient solution increases over time, hence why we top up with water or half strength solution. pH going down kzfaq.info/get/bejne/jL1mhcJ1v6fbfpc.html

+pogos kuregyan Hi Pogos, what are the PPMs of your source water and starting pH before you add any nutrients?

Fish food is chemical.

+dontbeknowing Thanks-do you really want me to read a little faster? A lot of folks give me stick for reading too fast! Please consider subscribing anyway and thanks for taking the time to give me some feedback. I appreciate it. Peace and happy growing, Everest.

Its perfect, just trolling

Heheh. Okay. Do you aerate your reservoir?

Zane Caldwell Thanks Zane. It's on the list. 103 will be a lot more practical and less theory!

Was enjoying the theory to be honest. Clears up misnomers you get in the forums. Thanks as always.

+Zane Caldwell If you're enjoying it Zane then sure we can go deeper, especially with that encouragement. Thanks!

Heheheh. Just you wait until pH 103! :)

+pogos kuregyan Your source water is 1,350 PPMs and you add nutrients to bring it up to 1,550 PPMs? Or are you referring to your water / nutrient solution's conductivity in miliesiemens?

+pogos kuregyan Yes Pogos, you should readjust your rising pH daily to keep it around 6.0. Iron, for instance, becomes much less available as your pH rises above 6.0. You probably already know that iron is a key component of chlorophyl-your plants' solar panels! If you don't care of your rising pH, an iron deficiency is in the mail!

Only I’m not on commission...

Thank you. Cat-ions. Cat-ions. Cat-ions. I will repeat 1000 times as homework :) Thanks again!

Man you are positive, make you even smarter keep it up:)

heh, but besides that, loving the video!

+Colin Godsey Thanks Colin :)

Thanks Nicholas-my bad. :)

Everest Fernandez you're good. love your videos, the science nerd in me had to say something

Hah same, awesome!

+Steven Deadilus Thanks Steven.

Kind of flows off the tongue, doesn't it?

🙇

+DrValerie800 Apologies for the spasm-inducing mispronunciation. Not as bad as the time I mispronounced the word "mispronunciation" in front of a girl I was trying to impress in high school. That was really bad..... :)

LOL; I can imagine. Not to worry, though, we all go through embarrassing mispronunciations occasionally. I have a huge vocabulary and it still happens to me. :-D

+DrValerie800 One should never be afraid of mispronouncing a word because it shows that you took the personal time to read it. But I hate the thought of corrupting others with it. Truly I do. Lol.

You say tomato.... :) lol.

+Nicholas McKenzie Thanks Nicholas.

THANKS so much Y.Jedi! I really appreciated that! +++++

Same, keep it up! All this trolls on an-ion, actually its latin, and right pr would be anion/cation, so who cares, as long the content is AWESOME?!
