Ok no problem you have to pass it the ph value. Can you email me the ino file and I’ll fix it up for ya.

What I sent was pseudo code it needed tweaking based on what you had already, variable names, etc. I should have been more clear. It was intended to describe the logic but not be copy and paste.

i knew my "phValue" needed to be linked somehow.. just wasn't sure where or how many times.

i figured your guide wasn't line for line but some of the caps and colors made me think you laid it out special for a reason.

i've ran all the hardware so far except for the relays thats the only wires i need to connect to the bench test yet.

i really appreciate your help Moe!!!!

i don't have a definitive answer on the pH tests yet. messing with me for sure.. so today after a full 24hrs the RDWC system has not moved at all. it's still 5.8 from when i added 5ml of up yesterday right before the race started. been 27 hours and it's still the same.. IDK it ain't broke so i'm in holding pattern.. i need to go back and look in my notes. Aqua Man taught me something a while back about the affects of water when air is not introduced before the nutes, i can't remember exactly what it was but i might have it written down or typed out. i'll check if i can't find it i'll bug him again on it.. it might be a factor in this. idk

all the other tests seem steady as well, the one that moved the most was the tap water with just ph down, that one drifted up 0.7
and the beaker with just plain tap and nothing added seemed to dive down a bit, i have everything written down and will continue to monitor.
it's enough that i need to do an extra dab or two to keep what little of sanity i have left!!!

it's pouring rain out now so i'm gonna add a beaker of that to the test... no rain collector or plumbing from it, just mother nature falling from the sky.

plants are growing, some slight issues that i'm not to sure about one my be slight mutation and the other might still be my leaf curl issue.. way to early to say for sure but noteworthy nonetheless!

i will say though one goal was for a better root base and not so one stranded.. i gotta say i need to take a mini victory where i can get it!!!

her downstairs first...





her cousins came over to play... a little SIP in soil airpot action!!! Funky Monkey

Racking my brain as to why you are either introducing a strong base or creating a reaction that results in one. This just should not happen with the chemistry as you describe it. There is something happening here that we don’t realize.

I am just trying to figure out what causes water to act like yours is.
No hydro experience at all but I get water.
From my line of sight, I feel there has to be an organic source of rot to cause such a drastic drop.

guys i'm pretty sure there is something in my rdwc system that is the problem. last night at 7pm i said it was fine, at midnight it was 4.8.. i put in a lot of up and some down to try and make a buffer to slow it down but all the samples were and still are perfectly fine. the sample of just the same solution has crept up 0.1. same with the sample with the coco in it, that bumped up .2. all the other samples of water mostly stayed steady. the water with just down came up a little but it was unaerated and the tiniest bit of down lowered the small amount so much i was expecting it to come up a little anyway. it's not diving at all and that was the test.

i didn't pour anything out and will continue the test but my heart sunk last night when that ph was low. i didn't want to believe it and even quickly cleaned and calibrated my ph pen (it was spot on anyway) because i didn't want to believe that rez was really that low, it was. it's fine now at 5.8 but i don't feel good about it and if it's low again tomorrow i will be confident it's something in there.

to be continued...

Man I have thought for the last 2 grows now there was a contamination in your system. I don’t know what. But the curled leaves last grow and this ph thing….

I would think it is fixable but probably not during a grow. I would expect that if you use a strong acid to bring the ph up to 10 and run the system holding it there for a few days it would neutralize the base that is causing your problem. Then run it a couple days with tap water and bleach. Finally draining and reset using rain water. Put in the nutes and get to 5.8 and run it for a couple days without plants. Verify ph sticks now

1 week without plants should reset this system for you I would think.

This sucks man sorry you are going thru this. I have never seen this issue before, new territory for me. I do not know what is causing it.

I used to make biodiesel. Big cone shaped vat that the waste oil goes in then other chemicals get added heated stirred then separated into bio and waste.

At the end there are certain tests you run to verify good product. Been doing it for a while and not having problems. Then all of a sudden I cannot pass a 3:27 test no matter what I do. Driving me insane. Multiple batches fail.

Turns out a rubber hand grip from my dirt bike that was on the shelf over the vat had fallen in at some point when the lid was off. Every time the methoxide got added to start the process it would start eating at the grip and destroying my batch.

I kicked myself for weeks over all the source oil I wasted because of carelessness but at least I had my solution. I think you have a hand grip somewhere in your rdwc. It will be obvious when you finally figure it out but right now it’s a head scratcher.

it was all of your first reactions to the symptoms. i probably shouldn't have rushed these plants in there.. rushing to fast always bites me in the ass! i never learn.

i want to look for whatever it may be, i would think this has to be a chunk or blob or something large enough to be seen?

the whole time release thing is just totally confusing.. i almost want to set up that new ph probe to a logger and let it go for a day and half!! it's like a mouse is peeing in my rez every night when i go to sleep! just weird how it's been doing this exactly every night. so messed up.

i knew this wasn't gonna be quick... sucks!

could my grip possibly be the seal in a can i used? or teflon goop for fitting threads? i mean it didn;t do it before but that don't mean it can't now i guess..

i've seen you using it on your lids so i figured it was okay.. i used the spray.

i didn't go check it yet today, lights just came on now..

I really wouldn't think so.

OK, first I need to apologize. I have been saying the PH / acid / base thing wrong. Your res is going acidic not basic. I'm a brain fart idiot. I also need to admit this is not the first time I got these wrong. Need to quit shooting from the hip.

Your issue is added acids, not bases, no matter what the idiot posted above. That said, you should probably take everything I post with a grain of salt.

If your water has no hardness which is the case with rain water, it would not take much to make the water drop or raise ph.

Here, listen to someone who does not have their head up the azz syndrome:

1. CO2 Concentration in Water​

The concentration of carbon dioxide (CO2) dissolved in water becomes a factor that affects pH. The reason is carbon dioxide triggers an increase in the concentration of hydrogen ions which makes the pH of the water decrease. That means when carbon dioxide is high, the pH of water automatically becomes acidic. This carbon dioxide can come from the atmosphere and air around polluted water. Apart from pollution, carbon dioxide also comes from the process of plant respiration that occurs at night, where much carbon dioxide is released. This causes the water to have a lower pH than neutral. While during the day, where many plants photosynthesize by releasing oxygen, the pH of the water will rise.

2. Temperature​

The temperature at which water is located affects the solubility of carbon dioxide. When water gets a lot of heat intensity from sunlight, the surface temperature will rise. When the surface temperature of the water rises, the solubility of carbon dioxide will decrease so that the pH will rise and the water is alkaline. Meanwhile, when the temperature and temperature decrease, then the surface temperature of the water will come down and automatically the level of carbon dioxide solubility becomes higher. Therefore, when temperatures are cold, the pH of the water will drop and the water will be acidic.

3. Carbonate and Bicarbonate Concentrations​

Next, the factors that affect pH are carbonate and bicarbonate ions which are basic. If water has a high enough concentration of carbonate and bicarbonate ions, the pH will change. From what was originally neutral, the water will turn into a base.

If initially acidic, it can turn into neutral after receiving additional carbonate ions and bicarbonate ions. Changes in water into a base due to carbonate and bicarbonate ions often occur in water flowing out of the mouth of the cave by passing carbonate rocks that contain calcium.

4. Organic Material Decomposition Process​

Decomposition is the process of decay that occurs in organic matter and living things that are in the water. Because organic matter and living things contain the element carbon (C), so when the decomposition process occurs, there will be a lot of carbon released into the water. However, because organic compounds tend to be unstable and easily oxidized, what enters the water is carbon dioxide and water itself.

Therefore, when there is carbon dioxide entering the water, it is certain that the pH level will change. Water that was originally neutral can become acidic because the dissolved inorganic carbon content can increase hydrogen ions so that the pH will decrease. Therefore, when working in a laboratory or industrial production process, it is better to keep water away from organic materials that can change the initial pH.



So maybe cut the bubbling in half to start with, and make 100% sure there is nothing organic in there to decompose? Maybe the time lag comes from the time the bacteria take to convert organics to waste?

I went back and edited the 2 posts where I said base vs acid for clarity and future readers. Again sorry if I threw you off.

I really wouldn't think so.

i didn't either and it's been in there since day one. just had to ask..

i totally missed right passed that man, i followed along and understood what you were meaning and never caught the typo!! haha great that you edited it for back reads!!! Thanks!!!

thanks a lot for this, some good stuff in here and now bookmarked!!!!

hmm.. my bubbles are quite strong. now that i think about it Smoke and i had a convo about this once before. I'm using an ALITA 6A pump, this is what i use for my rez and two buckets. sometimes i also bubble the mixing barrel with it too.


so i ran a line from my air manifold to my rain collector and another to a side project to bleed off some air. it's now at least half of what it was. it looks like this now, does this look acceptable?

tonight the rez ph was low again (5.0) the sample of this same solution from days ago hasn't moved. 100% confirmed.



so in a way it good that we know it's the system or in it and what to concentrate on.. and we know it's not my water.

even though we still don't know exactly what it is yet this is still way better than dealing with mites!!! way better!!! HA!
