v1.0 of Yet Another Nutrient Calculator is live

[wet]

Hi!

http://calc.petalphile.com is now at version 1.0

Here's some pics:



You can make solutions, dose by teaspoons, mg, g, whatever.


And then it'll say something like this.


It has these features:

* Support for more than 20 compounds/DIY fertilizers.
* Calculates all macro and micronutrients.
* Calculates dosing for the three most popular DIY methods (EI, PPS-Pro, and PMDD).
* Graphs and compares your results vs those methods.
* Friendly input: you could use 3/4, 0.75, or 0,75 teaspoons, for example.
* Dry dosing or solutions for target or dose.
* Solubility checks.
* Toxicity checks and a wiki for Copper.
* Warnings for tricky compounds (ex: K3PO4, EDDHA Iron, etc)
* Mobile-friendly interface available at http://calc.petalphile.com/mobile
* Approved by PlantBrain/Tom Barr!
* Open Source and totally Free: https://github.com/flores/yet-anothe...ent-calculator

Thanks!

Awesome! Thanks for creating and updating such a useful tool.

[Gatekeeper]

Great to see you back. I got your pm. Man, its been some time, but glad I was able to help.

Really nifty little tool. Bookmarked!

Thank you!

Sweet, I like the colored bar graph report, very smart.

Any chance you might add the combined Macro-Micro-CSM-B powder from aquariumfertilizer.com?

I got it by mistake (thinking it would be separate bags) and I'm trying to figure out how to dose it.

Cheers

Awesome stuff. I hate math so this is invaluable. Thanks!

[wet]

Thanks!

Sparky007 -- I'd love to. I'm pretty sure that by "parts" aquariumfertilizer.com is using volume and so I can get the proportions alright, I think. This might be an incorrect assumption and they may be doing "parts" by mass, though. Are you up for emailing them? (I've emailed maybe a year ago for something else and never got a response, but have also never ordered from them )

Do you happen to have a scale? If so, the mass of a teaspoon measured/averaged a few times is needed. If you don't, that's okay and I can mix up the same proportions and weigh it some point this weekend.

Hey Sparky007. I added AquariumFertilizers MacroMicro Mix to http://calc.petalphile.com

This guy is tricky since there's no information on their site, so I figured I'd explain how I did it.

First, let's assume by "equal parts" they're using volume, because almost everyone who says "parts" means volume. This would be doing something like adding 1 cup each of KNO3, K2SO4, MgSO4, and Plantex CSM+B into some bag and then shaking it up. Lets assume the mix gets evenly distributed.

Now lets pull a teaspoon out of that bag. That teaspoon will be 1/4 teaspoon KNO3, 1/4 tsp K2SO4, 1/4 tsp MgSO4, and 1/4 tsp Plantex CSM+B, of course. Such a teaspoon will weigh about 5.25 grams.

However, the mass of each of the compounds will be different and not 1/4 of the total. (KNO3, K2SO4, MgSO4.7H2O, and Plantex CSM+B all have different densities.) If we took each one of those 1/4 teaspoons, we'd actually have a mass like this:

		volume		mass (mg)	mass (%)
PlantexCSM+B	1/4 tsp		1075		20.5
KNO3		1/4 tsp		1300		24.8
K2SO4		1/4 tsp		1600		30.5
MgSO4.7H2O	1/4 tsp		1275		24.3
total 		1 tsp		5250

Now we have mass percentages, so the rest is easy. (All the % we know and love from our fertilizers are calculated by mass percentage, and so we have to speak apples to apples before we convert it.)

Lets look at all the nutrients of our MicroMacro Nutrient mix. Whats the percentage of each nutrient from each bit of the mix?

KNO3
	K:	 0.0957
	N:	 0.0343
	NO3:	 0.1519
K2SO4
	K:	 0.1368
	S:	 0.0561
MgSO4.7H2O
	Mg:	 0.024
	dGH:	 0.0017
	S:	 0.0316
Plantex CSM+B
	Mn:	 0.0038
	B:	 0.0024
	Mo:	 0.0001
	Mg:	 0.0029
	dGH:	 0.0002
	Cu:	 0.0002
	Zn:	 0.0008
	Fe:	 0.0134

We then take all those bits and add them up.

AF's MacroMicro Mix:
  K:      0.233
  N:      0.0343
  NO3:    0.152
  S:      0.0877
  Mg:     0.0268
  Fe:     0.0134
  Mn:     0.00383
  Mo:     0.000102
  Cu:     0.000184
  Zn:     0.000758
  tsp:    5250
  target: NO3

(I was rounding in the scripts above for the purposes of the thread. This guy does 3 significant figures at the end of all calculations)

Now lets check out what happens with 3 grams of that stuff into a 20gallon tank.


I'm not really down with this stuff, fwiw. I think the lack of PO4 and in particular the proportions make it smarter to roll your own mix.

Please correct me!

Hi.

Version 1.1 of Yet Another Nutrient Calculator -- http://calc.petalphile.com -- adds commercial premixed solutions. Here's a couple of examples:











It:

* Will let you calculate RootMedic and Pfertz (thanks for supporting our hobby!) initially
* Works off pumps, mL, or bottlecaps to make your life easier
* Is still in beta but you should have fun with it
* Works off the assumption of % being wt/vol, but please correct me

Check back to the calculator these next couple of days for:
* Seachem, Tropica, and more commercial fertilizers!
* Mobile site updates for these new features

Thanks!


Thanks!

Help me understand my results:

To reach your target of 10.0ppm NO3, you'll need to add 740.664grams of KNO3 into your 500.0 mL container.
Each 5.0 mL of that mix into 120.0 gal is:

Element ppm/degrees
K 6.31
N 2.26
NO3 10.00


KNO3's solubility at room temperature
is 360 mg/mL.
You should adjust your dose.

Why should I adjust it?

Too much KNO3 mixed into solution. It will not dissolve. 360 mg/ml, or 360 grams per liter. You are trying to put twice that in half a liter. It will be a chunky soup of solids.

it wont desolve in the amount of water you are using.
Ooops
ninja post while checking the math

Thanks guys!

It is looking very good and would be handy for me when doing setups and talks. Any chance of a dedicated web ap that wouldn't require web access after install?

Maybe mistergreen could help with that to some extent.

RootMedic would be happy to donate for initial costs and if you were to "charge" for the app, I'd offer something for free to every person that signed up.

Just let me know if you want to talk, wet.

Hey OverStocked!

First, this is awesome. Shops like yours are awesome for our hobby.

I can't commit to a desktop app for RootMedic's stuff. But I'm up for it and RootMedic can sponsor this project for a contribution or perks to your choice of AGA or SCAPE members (the clubs I am a part of). It's not a hard project, I just have my hobby computer machine time queued up for cooler http://ei.petalphile.com charts, some new tool for folks who find the existing calculators too hard, and some other stuff.

However, all my calculators are opensource -- MIT license: do whatever you want with it -- at the GitHub link above, and if anyone else wants to tackle your project, or build a cool frontend for my calculators, or anything interesting, I am eager to help with, support, and contribute code/time/ideas!

The mobile site is live for all of RootMedic and Pfertz stuff, by the way.
