Mixing stock solutions from now on
Thats funny was thinking that same thing, I just don't want/worry about stock mixes dropping out and having a bunch of shit in the bottomDo you find it easier? I felt like dry weigh nutes were more natural for me, scales and I go weigh back hahahaha
And yes that was a pun
As a fellow jacks user I feel once it's dissolved you wouldn't get much if any fallout. Maybe give it a good shake.Thats funny was thinking that same thing, I just don't want/worry about stock mixes dropping out and having a bunch of shit in the bottom

Beautiful!I used 5280 grams of 5-12-26 in 6 gallons of water and 3480 grams of cal/nitrate in 6 gallons of water.
@10 ml per gallon of each I get 850 ppm.

I do agree organic veggies always seem just a lil bit sweeter:) Looks like I need to start growing more of my own food as well.
Tried to find the levels of toxic metals in this product, went to the common sites but no luck, have also contacted J.R peters to request a list of heavy metals for the hydroponic formula.

anyone know of a better site to check ?

I did find a more detalied label for the two products, and have inluded them as a pdf download, you DesertS where you at:DView attachment 149094

what program did you use to calculate your stock solution?Maximum solubility is 3 lbs per gallon of jacks hydro 5-12-26. No dropping out of solution worries here
what program did you use to calculate your stock solution?
This is quoted from the JR Peters Blog and it is also the same instructions sent with the fertilizer when shipped.
" To make 10 gallons of solution follow this formula: In 10 gallons of water, dissolve 1.3 ounces of 5-12-26, when that is totally dissolved add 1 tablespoon of Epsom salts for extra Magnesium and Sulfur. Finally add in .86 ounces of Calcium Nitrate. This will give you 150ppm of Nitrogen, which is the perfect rate for growing hydroponically."
Converting Oz's into grams gives us the following:
Jacks Pro Hydro 5-12-26 gram weight= 36.85 ( 1.3 Oz)
Calcium Nitrate 15-0-0 gram weight= 24.38 (.86 Oz)
Looking closer at the ratio between the two we can observe that there is a .661% difference. Or, for every 1 gram of Jacks you must mix .661 gram of Calcium Nitrate. (24.38/36.85= .661)
There it is, boom. If you mix the stock solutions according to that ratio by weight in grams - equal volume of each Jacks hydro and Cal/Nitrate will lock in the NPK ratio. This is our main goal.
And so I concentrated my stock solution making sure not to go over the 3 Lbs per gallon cap while keeping in mind what ppm I would achieve @ 10ml a gallon of each stock solution. You may choose to mix more or less into a stock solution depending on what you're mixing preferences are. Do you like hitting you're target ppm @ 10ml per gallon of each or 5ml of each?
*Important Note
I actually had to add 10 more grams of calcium nitrate to my stock solution (listed above) to achieve the .661 ratio correctly. I messed my initial calculations some how. Total cal/nitrate grams for my stock solution in 6 gallons of water = 3490
Also, my previous findings of 850 ppm when mixed @ 10ml per gallon each are incorrect when using the grams of each I listed above. I Believe it is 650-700 ppms.
Overall I am easily mixing my reservoirs now- no more waiting for salts to dissolve each time. I also check my solutions with a ppm meter when mixing. I have posted an equation in an older post that details how to mix according to ppm meter and I would advise following those guidelines if you are getting used to mixing reservoirs with stock solutions. Ya know, so you keep the ratio's the same in the rez just incase you slightly strayed from the .661 ratio some how.
More power to the people. Hope this helps.
@Capulator What is this software ? need a link to it Bro, I'm diving head first into this shit...:cigar:
3.0 grams/ gal of hydro comes out to 680 ppm on a .7 conversion = .97 EC
1.0 grams of epsom salt comes out to 120 ppm= .17 EC
1.8 grams of cal nitrate comes out to 330 ppm =.47 EC
This was all measured after I added each to 100 gallons of demineralized (RO) water in the order above, and waiting for EC to stabilize before adding each additional part.
Total EC using demineralized (RO) water= 1.61
I measured it all out with my triple beam to the tenth of a gram.
As it turns out:
1/8 tsp of hydro = 1 gram
1/8 tsp of CaNO3= .9 grams
1/8 tsp of epsom = .5 grams
...high folks, i'm new around here, or rather, i've not been around for a couple three years, so i've not had the time to read through the thread but i thought i'd announce myself as another Jack's Pro fan, i've been running it in my coco hempy's for the last couple of years and i love the stuff.
...anyway, just stoppin' in to say 'hey'.
peace, bozo
