Adding Calcium and Magnesium
    #301212 - 10/21/09 06:10 AM (11 years, 4 months ago)

Hi There,

I was recently watching a video on youtube about hydroponic solutions, and the guy doing it said in addition to using "Grow," "Bloom," and "Micro" solutions, he also dropped in dietary supplement tablets containing calcium and magnesium. So my first thought was "Oh, my guys could probably do with some as well."

So anyway, I have this stuff at home and was wondering if it would be beneficial and if so how much should I add?



Right now I'm using the "Advanced Hydroponics of Holland" stack, and Big Bud as well.

I wouldn't eat those pills either so go ahead and try to compost em. You should know you will have to do some without and some with so you'll know the results. Take pics!

In response to the amount, I would guess you would want about 5-20 pills crushed throughout the soil or 5 crushed per gallon.

If the correct micro and macro nutes will be used by the plant I sort of doubt but that is my non-informed opinion.

Hopefully this won't kill the plants. Unfortunately, I can't do two test groups, but I figure I will notice a significant change, good or bad....

Alright, 6 hours later and they're still kicking. I guess that's a good sign.

The water is very murky now though. I cannot see the pump in the water. I also added some urine and 3 extra liters of water.

Was that a bad idea? Other than the murkiness though, I've only seen improvement in the plants. I have a feeling that's more of a result of the PH calibrating I've been doing since yesterday.

In any case, I'm not sure the extra calcium and magnesium helped in any way but the plants are growing well.

Well, I added 200ml of urine, only because I read it really boosts nitrogen levels, which I discovered my Advanced hydroponics of Holland stack is a little on the low side.

I didn't think it would be an issue considering that the cultivation guide on the site suggests adding urine to the nutrient solution. Should I flush the system?

Wow I don't know how I missed this, but I just saw this post today. I'm doing an immediate flush right now.

-Edit-

Total Flush complete.

-Edit-Edit-

Yeah, totally cleaned the system. Washed all the tubes, scrubbed the rez, and even cleaned the inside of the flood chamber. All the plants were flushed with clean water too before being put back in. The system is now only using the AHOH stack, Big Bud and clean water. :-)

Sorry about everything guys. Thanks for your help though.

Sorry Spency but I am laughing so hard on multiple levels now...mostly because of Harry's comments...too funny dude.

I gotta throw in my two cents...why in the hell did you add pee to your plants water...lol.

Anyone who told you to do that should be pissed on...lol.  If you need to boost N levels, do it the proper way...with Nutes.

"I didn't think it would be an issue considering that the cultivation guide on the site suggests adding urine to the nutrient solution"

Really?  Do you have a link to this guide that says to do this?

Also, doing something and waiting 6 hours for results...well sometimes it can take days before you see results.  Although I always find that positive results take days to appear...damage happens so fast it makes you want to cry and vomit.

"did you seriously just fucking pee in your hydro reservoir? why in the motherfucking fuck of fuckerlot would you do that?" - Hahaha...love it...I am laughing so hard I am crying...time to get high.

Before trying to make me look stupid, you should read the cultivation guides on this site. There's only 1 really.

http://www.growery.org/2796/Cannabis-growing-guide

Scroll down to Vegatative Growth. If you don't want to, here's a direct extract from it:

"HYDROPONIC VEGATATIVE SOLUTION, per gallon:

Miracle Grow Patio (contains trace elements) 1 teaspoon

Epsom salts 1/2 teaspoon

Human Urine (OPTIONAL - may create odors indoors.) 1/4 cup

Oxygen Plus Plant Food (OPTIONAL) 1 teaspoon"


That's a lot of urine imo. Much more than I actually added.

Here is where I got the original idea:
http://www.hydroponicsonline.com/forums/hydroponics/1427-better-tomatoes-urine.html

A guy said he just took a leak in the system and saw massive improvements. I only added 200ml just to test it out myself.

Also heres some stuff I just pulled off of google:
http://forums.gardenweb.com/forums/load/hydro/msg0112194811411.html
http://www.howtodothings.com/home-garden/how-to-use-urine-as-a-fertilizer (I think this article said something about NASA using urine in their hydroponic systems)

That's my experience as well. My exact word were, "6 hours and they are still kicking." To clarify, what I meant by kicking is not dying. Also, I had the system running this solution for several days and actually noticed an acceleration in growth - I took measurements of the plants as well as general notes about appearance each morning and night. I was very impressed. However, I am not advocating adding urine to the reservoir - in fact I think this acceleration was more of a result of the PH calibrations I've been doing using Organic PH Buffers. However, I did not see any hindrance; only improvement - with the urine in the system. If you like, I can post pictures of the plants. I only just flushed the system 6 hours ago, so certainly they could not have improved in that time right?

I'm glad your amused, and I admittedly found that particular post funny too. However, I hope it's clear now that I did this with somewhat of a foundation.

I respect you a lot Azyle00, you've been really helping me and giving me some solid advice regarding my vent system. I like feedback, and advice - it's how I learn and improve, but I found it hard to derive any sort of useful information from your "2 cents." It seems to me that you just came here to beat me down, when I'm already on the ground. So, I'm sorry if I came off a bit harsh in this post - but I wasn't quite sure how else to respond to you.

So I hope there are no hard feelings and I hope everything is clearer now. :heart:

well it does seem to me that you at least did your research in this case, which IMO puts you miles ahead of some of the n00bz I've seen around the web. That said, the vast majority of food humans consume is so artificial and nutrient-poor that it's downright toxic for most plants. If you're a health nut vegan, then you may witness some different results, but I can guarantee 100% that if you eat fast food on a regular basis your poop will NEVER turn into manure for fertilizing

As it just so happens to be I'm an organic food nut and a vegetarian. I couldn't say I'm healthy (smoker) but what I eat is. Haven't eaten anything close to fast food in a couple of years now. Beer and wine might be a problem.... :tongue:

Anyway, let's close the lid on this. This system was emptied, scrubbed down and refilled and now only has the AHOH nutes and big bud in it. Again I don't actually know if the urine helped, but It took me about 3 and a half hours to clean my thing up, so believe me, I'm not willing to do another urine experiment.

Nonono...you overreact, I just found the whole thread quite amusing, whether right or wrong.  Not at all attacking or saying you personally are an idiot or anything like that (which is why I wanted a link to where you got the info), and honestly read what I posted...in no way do I say anything to put you down.

Never ever have I personally heard about human urine being used to feed/aid plants.  I still do not believe it, despite it being in that guide and I think the "Optional" was a good clue that perhaps it is iffy.  Never read the goodle stuff you linked yet, maybe there is some validity to it...so I stated my opinion, asked my question of your source and laughed hard over Harry's comments and the whole situation.

But you were too harsh and now I am not laughing...I am crying and my feelings are hurt badly...just kidding :smile:

I would be concerned about your urine being bad for the plants because you smoke?  Cigs?  Nicotine is poison to weed plants.  However, if you are a health nut then maybe you could produce the urine that this guide had suggested, but Harry is right, the average human diet would make both urine and feces from said human not productive and likely harmful.

If you were truly posting like a complete noob incapable of doing some research, I would not even post answers, but I can tell you are intelligent enough to figure out things and research etc.  HB is correct that a lot of the noobs here post shit that places your knowledge miles ahead of them.

Remember to clean those hands of nicotine before you touch the plants though if your a cig smoker.

Hrm...read those threads over and I can honestly say they do not convince me at all that there is sufficient evidence for this to be valid...even read the part where the urine is supposed to sit for 6 months before being used.

It is experimental and controversial and imho if that is the case for a theory...it makes great for an experiment...but not worth the risk with your babies.

Again...you were reading a guide on this site that actually indicated that Urine was a realistic additive...whether the guide is right or wrong...we tend to hope and believe that these guides on Growery are fine to follow and contain true and tried methods and information.

Completely understand why you did it :smile:

Congrats on doing your homework Spency :thumbup:

We all enjoy when members post links to references!
You took an educated guess by what you read, it just so happens that is not such good advice. :shrug: But you corrected the problem and now learned something. Patients is definitley a virtue when it comes to message boards such as this. Good advice sometimes takes hours to days. Research like you did is the way i go while i'm waiting for some answers. Then use both to accomplish what i set out to do!

sterile at first but promotes bacterial growth. why do you think 20 min old piss stinks worse then fresh pee?  and in survival you never store piss you have to drink it right away because of that. not sure if that comes in to play in a hydro set like i said. :smile:

Oh sorry, my misunderstanding.

It came off that you were taking the stance that my actions were absolutely wrong and beyond justification, mainly because you said this:

So sorry for over reacting. :smile:

the man said:

That's not actually true. Urine is actually loaded with nitrogen (ammonia Nitrogen to be specific), when exposed to our atmosphere I think the nitrogen slowly leaves the urine and leaves behind ammonia. This is actually where the smell comes from. I really don't think urine promotes bacterial growth. Also, I'm fairly certain ammonia by itself is incredibly toxic so if anything it would kill bacteria - that's just a guess. I think that's also why people say to pee on an open wound if you need to sterilize it but don't have anything else to do it with - this would seem counter productive if urine promoted bacterial growth, and I'm pretty sure it's fact that it works as a makeshift sterilizer.

I've been reading more about urine being used as a fertilizer. Apparently, it's an excellent fertilizer if it's used near immediately and heavily diluted with water. One guide said the ratio of urine to clean water should be about 1:5. The reason it should be used immediately is because the nitrogen leaves the urine quite fast.

I would think urine would be an excellent soil additive, as the ammonia left behind would eventually be washed away anyway - however, hydroponically, I'm not sure it would be as beneficial because of the lingering ammonia that would circulate the system.

In any case, I now fully realize how unbelievably sensitive pot plants are. So while a hardy plant like a tomato plant would be able to tank the ammonia and actually benefit from the nitrogen, pot plants may not be able withstand the ammonia as effectively.

You are correct about tomato plants.  Strawberry plants too.  They are survivor type plants.  I grow tons of straw plants and have seen my babies get decimated by a multitude of things and they just refuse to die or suffer.

We had a hail storm in July that punched holes through all my plants leaves, then a drought while I was away for a week after that storm, I came home and they looked dead.

They all lived, they all regrew and all churned out crops.  They are still alive and producing berries even today and it is almost Nov and we have had frost...yes they are in baskets hanging even.  It is like they do not care.

Tomato plants in my experiences are similar.

Weed...well we all know, you can look at a weed plant the wrong way and it will wilt lol.  But then weed is a survivor plant too, hard to kill, but easy to fuck it up so it does not perform and produce the way we want it too.

Not one thing in this entire thread is gonna help plants grow. Go and get a good hydro solution. Hydro solutions are complete and are not short on anything. They will not be short of calcium and magnesium that is a problem found in shitty soil.


Man I swear you guys make my head hurt sometimes.

Well actually if you do a bit more research on the subject of urine as a fertilizer you would find these...


---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------


This is a scientific study published in The Journal Of Agricultural and Food Chemistry, that was conducted using urine to fertilize the tomato plant.  It's great, you all should really read this one.

Stored Human Urine Supplemented with Wood Ash as Fertilizer in Tomato (Solanum lycopersicum) Cultivation and Its Impacts on Fruit Yield and Quality

http://pubs.acs.org/stoken/presspac/presspac/full/10.1021/jf9018917?cookieSet=1

Excerpt:
"The new study found that plants fertilized with urine produced four times more tomatoes than non-fertilized plants and as much as plants given synthetic fertilizer. Urine plus wood ash produced almost as great a yield, with the added benefit of reducing the acidity of acid soils. "The results suggest that urine with or without wood ash can be used as a substitute for mineral fertilizer to increase the yields of tomato without posing any microbial or chemical risks," the report says."

Quote:
Urine typically contains 70% of the nitrogen and more than half the phosphorus and potassium found in urban waste water flows, while making up less than 1% of the overall volume. Thus source separation and on-site treatment has been studied in Sweden as a way to partially close the cycle of agricultural nutrient flows, to reduce the cost and energy intensity of sewage treatment, and the ecological consequences such as eutrophication, resulting from an influx of nutrient rich effluent into aquatic or marine ecosystems. The fertilization effect of urine has been found to be comparable to that of commercial fertilizers with an equivalent NPK rating.

Excerpt:
" Urine as a fertilizer- Urine is a locally produced resource that is free.  As a fertilizer it is effective, is a high quality fertilizer, urine is sterile and requires no processing other than dilution, is readily available, can be used immediately or stored, rapid acting, and is easily applied. Urine provides a constant supply of fertilizer, instead of the annual or semi-annual composting systems that require physical labor to aerate and require management.
As a fertilizer, urine is rich in nitrogen and also contains substantial amounts of phosphorus and potassium.  A family of four produces enough urine to fertilize 1/3 of an acre at a rate compared to the application of 100kg per hectare in developed countries -note that Africa currently has the lowest fertilizer use in the world at 8.5kg per hectare.  The use of urine as fertilizer has been studied by Arba Minch University  in Ethiopia and the Sodo Agricultural Department investigated the use of human urine as fertilizer for different crops. Their research indicates equal or higher yields of maize and wheat when fertilized with urine when compared with the applications of chemical fertilizer."

Quote:
"Urine contains large quantities of nitrogen (mostly as urea), as well as significant quantities of dissolved phosphates and potassium, the main macronutrients required by plants. Diluted at least 8:1 with water it can be applied directly to soil as a fertilizer. Undiluted, it can chemically burn the roots of some plants, but it can be safely used as a source of complementary nitrogen in carbon rich compost."

Excerpt:
"Tushabe added that human urine is a good fertilizer because it contains nutrients that support plant growth.
He noted that in countries like Ivory Coast, Eco-san toilets have increased agricultural production by three-fold."

Last but not least  here are a ton more links about the use of urine as a fertilizer.  you too can find out by typing in "urine fertilizer" into Google!! In case ya'll aren't familiar with this procedure I have enclosed a link here that does just that for you!!

These types of situations arise often throughout history.  Certain people that think they know, excuse me "know" what can and can't be, burn someone else to the stake because this other has a radical different idea than what others have previously thought. 
Galileo ring a bell...  Burned to the stake for claiming the the earth was not the center of the universe..  Who was wrong there??  Many more of these figures exist, some more famous than others(Darwin, Cuvier, Lamarck and Patrick Matthew, etc) with many different fates.  One thing they all did was to change the world drastically.  One of the best ways to come up with knew ideas and knowledge is to experiment. Yea, you mess up and have to start over, but this is where the cutting edge is.  People not afraid to test out new idea, even if these go against the main stream.  Their all sheep anyway.  Following what others have already Donne, can't blame them, for the most part it works. 

I think it's great what you did experimenting with urine in hydro.  Perhaps you can give it a try again, with more refined techniques, and a control, on regular nutrients, GH perhaps.  Also maybe trying to find other complementary things to use along side of urine, especially during flowering.  Good job, don't ever listen to anyone who tells you  you can't do something or that something can't be Donne.  Anything is possible.

I'm sorry I don't mean to sound condescending, but I study botany, and very close to getting my degree.  This is one of my greatest passions, and urine as fertilizer is one of the greatest realizations of our time.  It is a way of promoting sustainable agriculture that doesn't rely on buying expensive chemical fertilizers from conglomerate sized corporations like Monsanto :thumbdown:, who has no care or thought to the poor farmers that it hurts inside and outside of our borders.. multinational conglomerate machines engineered for the sole purpose of acquiring $$$$, and patenting Genetically Modified life at any cost (to everyone else).  We need to improve our knowledge banks and find other green ways of living, to stop evil corporations like Monsanto, and reclaim what was never theirs to take or patent... LIFE!

Hope this helped a bit, hopefully we'll get to see more research done with urine in Hydroponics.  It can be done, it just needs to be refined.  Also I hope many of you will watch the movie/documentary "Future of Food"  Did you know Monsanto's GM Corn is registered a s a pesticide!!  No Shit.  Yummy.  Watch it and find out why this is so.

Peace
Ish

sterile at first but promotes bacterial growth. why do you think 20 min old piss stinks worse then fresh pee?  and in survival you never store piss you have to drink it right away because of that. not sure if that comes in to play in a hydro set like i said. :smile:




Mammal urine degrades quickly because it has a high nitrogen content. The high nitrogen content is present because mammals excrete the unused nitrogen from proteins contained in their food through urea. The urea makes up approximately two to five percent (2-5%) of the urine content. After the urine is excreted by mammals, the easily released nitrogen from the urine combines with hydrogen in the urine to form ammonia.

For $20, and that's in Hawaii, you can go get a bottle of Cal-Mag, one teaspoon for one gallon of water. 500 teaspoons per bottle. Easy/cheap
Hope this helps.  Aloha  Walter808

Hi There,

I was recently watching a video on youtube about hydroponic solutions, and the guy doing it said in addition to using "Grow," "Bloom," and "Micro" solutions, he also dropped in dietary supplement tablets containing calcium and magnesium. So my first thought was "Oh, my guys could probably do with some as well."

So anyway, I have this stuff at home and was wondering if it would be beneficial and if so how much should I add?



Right now I'm using the "Advanced Hydroponics of Holland" stack, and Big Bud as well.




are you using tap water or R/O water? if your using tap water ur calmag is probably fine, if ur using r/o you should get a bottle of liquid calmag. will probably work much better than those pills. i put 250 ppms of calmag in my r/o water no matter what before i give to plants.
