I'm making my own custom nutrient profile with Canna mono calcium.

Label is obviously misleading, as they state 15% Ca and nothin else. MSDS says it is Calcium nitrate Ca(NO3)2 in water solution.
Ok, so it has also shitload of Nitrogen!

But, how much?
And also on the back they state 11,6% m/m CaO. How is that possible? Sholud be other way around?

I'm using Cannastats calculator for calculating profile and have no clue, what to put in it.

Looking other Calcium nitrate fertilisers, I'm estimating ratio of Ca/N of about 11/9.


Thank you for your help

The dry calcium nitrate double salt is 15.5% nitrogen and 19% calcium. So if you dilute it in water to the point where the solution is 15% calcium, the total nitrogen content of the solution is approx. 12.24% (11.37% nitrate and 0.87% ammonium).

Calcium is 71.74% of the CaO (calcium oxide) molecule. So 71.74% of 15 is 10.6

Thank you for this.
But they clearly state 15% Ca in front of the bottle and 11.6% m/m of CaO.
Sorry, but still don't get it....

I'm usin RO water and need to supplement a lot of Ca, and N obviously messes with my nutrient profile. A LOT!! I get Ca def quickly otherwise.
GH Flora duo base nutes, btw.
So, what numbers should I put in calculator? 12N and 15Ca? Hmm.....

Thank you

I see now what you are talking about. Yes that is bassackwards. Obviously an error on Cannas part. Have you contacted them regarding this?

Best regards,

Canna tends to be fairly reliable when labeling and given non-compliant labeling can result in product recall is places like Ca and Oregon manufacturers tend to work hard at getting it right. I'd be inclined though to lab test it to get a reliable picture.

fucked up..if you are right and i think you are

you will have plenty of N in your "mono"

It dont make any sence that you have 15% Ca in solution from 11.6% CaO.

You need to find out if you can trust the numbers, personally i would switch to a more professionel solution


side note, its really difficult to make a mono calcium product, you need to evaporate the nitrate ect, also the end solution would be quite reactive so when you mix with other products to make your feed.
the Ca+2 would find a ionic partner and if any sulfur is around in the solution, the Ca would make gypsum and percipitate out of solution properly adding with it some iron and other trace elements.

So most solutions on Calcium use either calciumnitrate or wuxal products.

Calcium nitrate based products is regarded as the most effective way to give a plant calcium, quick and effective, non organic =)

Could you post a pic of the msds, i tryed to find it online but nada, just lame sale pitches =)

It could also be calcium chloride - thing is its entirely speculative until it is tested. CaCl may not be a bad thing in RO water where no Cl is present (maybe 1ppm) but use it in a tap water supply that has a high Cl content and things could quickly go pear shaped. Actually we analyzed a Botanicare Cal Mag product which contained 3.3% Cl, 3.1% Ca and 1.38% Mg - thing is Ag regulators don't require the listing of Cl so often (almost always) it is never listed. Logic tells me this is the way Canna may have gone if the product is being sold in States where regulators randomly test products for mislabeling --- i.e. it isn;t mislabeled because there is no need to list Cl. Shonky shit either way and why not buy another product that does make sense re labeling?

Thanks Avenger, qoute from link

"Preparation based on substances including water and calcium nitrate"

Pretty straight forward - calnite add water and you got canna's mono Ca, LOL

based on that i really dont think they evaporated the nitrates.
