Reverse Engineering everyone's nutrients

Its now 3am and i work in the morning so i haven't read past page 6 yet. But what i, a complete beginner to growing, have taken away from this so far is the following:

a) There are a ton of different companies with brands of nutrients.
- this one seems obvious, but most of these companies i haven't heard of before. there seems to be 10x more than i realized
b) All the different brands seem to do the same thing, with the obvious differences coming into play with the 3 different stages of your plants.
- this was my biggest take away, as i've always seen people arguing back on forth on which nutrients to use any why, with no really facts to back up there argument. When you take "a)" into consideration, this makes learning how to grow way more overwhelming then it needs to be
c) You can save a ton of money by buying the chemicals yourself and mixing them

d) Unless you have the ability to run tests on your soil/water/plants for deficiencies, and then want to mix for your own plants specific needs like a badass, a general blend of nutrients is fine for everyone else.





Mixing your own nutrients (specific to your plants needs or not) to save money becomes ever more valuable the larger your grow-op is. I'd be interested in knowing how big your grow-op is, OP, the amount of fertilizer you use monthly, and the monthly cost difference between brand-name and self-mixed is for that grow. (ignore this if you've discussed this at some point in the thread as i will eventually get to read it)

An issue i have, is i already have brand nutrients bought. Its only an issue for people like me who are getting into growing now that its legal where i live. As much as i would love a grow-op of 20+ plants, i'm too chicken shit to do it and don't have the room too even if i wasn't. so i'm suck to 4 small plants and the brand name blend i already bought that will last me was seems like years now. Not to mention when its finally gone, i'd have to invest in a way to weigh the chemical compounds for mixing. id have to do a cost break down to see if its worth it i guess. However this has REALLY made me want to throw it out and mix my own :mrgreen:

Thank you so much OP!! This has helped me tremendously with a lot of uncertainties floating around in my head in regards to nutrients!!

While it is not a nutrient I am still trying to work through reverse engineering Lost Coast's Plant Therapy since it is such a simple concept.

Label:
Organic Soybean Oil 38%
Peppermint Oil 0.5%
Citric Acid 0.25%
Inert (Water, ISO Soap, Sodium Citrate) 61.25%


I made some with oil, alcohol, soap, and peppermint at 1 jigger each of oil and alcohol and used it on a test plant. Not the same sheen. I bought some PT yesterday and it smells way more flammable than I thought and is more viscous which could be soap, oil, or citrate. For some reason, I originally had decyl beta d glucopyranoside on my list but I am unsure why. Maybe from the SDS? (YEp)

Just to confirm I am understanding the method here, for example I could add 12.5g sodium hypochlorite to 100mL RO water to get the solution, then add 18.6mL of this solution to 10L of RO water.

End result, is a 10L jug of UC Roots?

I usually find it easier to by a 12.5% solution. Mostly because a 12.5% solution is easy as shit to find. And it's pure.
And something to remember: 12.5g/112.5g =/= 12.5%
If you want to use 12.5g to make a 12.5% by weight solution, you need to add 87.5g of water, 87.5mL.
Also, you'll want to make sure you're using a graduated cylinder or a burette for measuring out the liquids in this case.

Cultured Solutions UC Roots
This is a 0.028% solution of hypchlorous acid. Most likely created via a solution of sodium hypochlorite. There's been a fair amount of documentation in the hydroponics world about the uses and benefits of sodium hypochlorite. Look for them somewhere else.

To make your own 0.028% hypochlorous acid solution from a 12.5% sodium hypchlorite solution by weight (15% by volume), add 7mL per gallon.

12.5% sodium hypochlorite: 7mL/gal (1.86mL/L)

Let's say I have a bucket of 20 liters of sodium hypochlorite acid at 12.5%
To make a 0.028% solution of hypochlorus acid.
I want to make a 1 gallon solution since creating a 5 gals is useless (I guess it's less effective overtime?)
I have to add 7ml of sodium hypo to 1 gal of water... as stated by Misterblah
But then Klx is asking if he has the right way: 12.5g in 87.5ml of water to make a 12.5% solution but then add 18.6ml of that solution to 10 liters... it gives the same .02308

How do we calculate the .028% vs 12.5%

7/3790 = 0,0018469656992084... * 12,5 = 0,0230870712401055 and not .028% as stated... So I am kinda confused...


Also, another question, if we have a 65% solution instead of a 12.5%, we simply divide the 65/12.5 to calculate the amount needed?

Thanks for help :)

Lol, I don't remember on which page but... All of sudden, oh sorry, a lot of error cut&pasting... We don't have any clue which one is good or not :P

Hi, it looks interesting to follow your point of view! But I searched your article and didn't seem to see any growth logs about plants! I am eager to know~ How do you achieve precise control of the NPK ratio according to your practice?

If you are starting with a 12.5% sol'n of sodium hypochlorite and dilute it it is no longer 12.5% so that doesn't work.

To make a 0.028% sol'n from your 12.5% it's easiest to use metric measurements throughout. A USG is approx. 4L so we'll go with 4L or 4000ml.

As we need to figure out how much of the strong stuff to use to get our known volume and percentage of dilute sol'n X will be the amount of 12.5% needed for a 4L batch.

12.5 x X = 0.028 x 4000
12.5X = 112
X = 112/12.5
X = 8.96ml

9ml is close enough to add to a gal jug to get you really close to your desired 0.028%. 5ml to a tsp if that's all you have for measuring with but a syringe would be a little more accurate but it's not critical if you're off a half ml either way. I would use a 10ml graduated cylinder but most people don't have one of those laying around. I'm not most people tho. ;)

:peace:

Thanks, I found out how to do hypochlorous acid the right way :)

My stuff is fresh, no more 6-8 months shelves bottles that is loosing 1-3%/day... Sad thing!

I can't see the original post you quoted from for this?
