ATTN JACK's Professional users: who has tried their new "Hydro Herb"?

I have been using Jack's Professional Hydroponic + Calcium Nitrate for a while now and absolutely love the results! Couldn't be happier after trying many different much more expensive base nutes.

Throughout my experience with Jack's I've kept in contact with Jr Peters Lab picking the brains of the technicians and have been told just the other day about how sweet this new "Hydro Herb" product really is.

Basically it is a one stop shop for your base nutes (at least throughout your vegetative stage, after that you will need to adjust your NPK ratio by adding "blossom booster" or equivalent).

For those who are new to Jack's, if you are like me and have been using it before this new hydro herb has been released for sale then you have 2 different bases, Hydroponic + Calcium nitrate.

These must be mixed individually and in a specific order to ensure precipitation does not occur. Really isn't difficult, pretty simple actually but it does become more time consuming when "topping off" your resevoir, or mixing smaller, more specific PPM mixes.

Also you must be sure that you do not mix these together when the solutions in the tank are concentrated. For example: Say you have a 50 gallon resevoir and you first dissolve your "hydroponic" mix but only dissolve it in 10-15 gallons of fresh water, well you should NOT dissolve your "calcium nitrate" in that concentrated mix without first diluting it down by adding the appropriate amount of h2o for your 50 gallon tank.

I am very interested in trying this one bag mix. The JR peters technician seemed to be in favor of using this new product and the convenience side of it has me sold to try.

Wondering if any others out there who are using the most amazing ferts out there (jacks of course) are using this new hydro herb?

I will be posting more on it after ive tested it within next few weeks!

GUARANTEED ANALYSIS F1313 Total nitrogen (N) .......................................................... 5%
5.00% nitrate nitrogen Available phosphate (P2O5) ............................................. 12% Soluble potash (K2O) ...................................................... 26%

130 oz / 1000 gal
3705 g / 3785 l

3705000 mg / 3785 l = 979 ppm

N 979 X .05 = 48.95
P 979 X .12 = 117.48
K 979 X .26 = 254.54

N 49+ 101 = 150
P 118 X .436 = 51
K 254.54 X .83 = 211

Actual available PPM:
N 150
P 51
K 211

Or 3-1-4

Seems like a great profile for veg and bloom. However, i haven't used it.

math lookers good to me
maybe 101 divided by 15.5% or 155 = .65 g/LCaNO3 ?

Interesting find guambomb! I use Scotts Professional and this seems like a bit easier to use than mixing the fert + calc nit. I hope someone takes the dive and gives it a go! Even though I dont mind mixing one by one, i am always interested to hear about new products from reputable companies!

So we are looking at 15-12-26 (check me math) vs 16-4-17?

That is interesting. Does anyone have the actual GA on this? I would definitely be interested in the Ca and Mg levels.

I suspect the new level of P is actually a good thing. I wonder about that K:N ratio though. My guess is it is most excellent for veg/stretch but I would think it is a little low for flower. Then again, what the hell do I know.

It has not yet been registered in Washington or California so one would have to depend on J.R. Peters guaranteed analysis claim. The product photo of their label on their site is not of high enough quality to be read after being enlarged. However it is possible the only fertilzer contributing to the calcium is the calcium nitrate thereby meaning the nitrogen is possibly all nitrate. I doubt that is the case though.

However if it is all nitrate, according to hydrobuddy the Calcium ppm would be about 144.5 ppm if the Nitrogen contribution from the calcium nitrate is 101 ppm. IMO The possible lack of 15% or so of ammonical nitrogen would very likely lead to a continual rise in pH if growing in an inert medium or aeroponics with a recirculating reservoir. If no other calcium is provided in a soil type grow pH rise would also likely be a problem. There is not enough phosphorus to act as a buffer for any length of time.

So I would consider that the initial Nitrogen provided is ammonical nitrogen or at least in part ammonical nitrogen and therefore it is hard telling what the magnesium and sulfur level is as there are just too many possible options. For an example using ammonium sulfate to supply all the nitrogen as ammonical nitrogen if used in conjunction with magnesium sulfate would supply a heck of a lot of sulfur if shooting for a fair amount of magnesium.

Surely someone contributing to this forum has bought some of the new J.R. Peters product and will provide the magnesium and sulfur levels.

Disco, give it a go, I am sure you will love it!! I thought it was funny when I was these nutes. Between the Scotts and the Calc Nit, it was approx $70. But with how much i water, the two bags will last decades!!

Here it is...a little ammonium nitrate in there.

Some would say not listing the % of sulfur in the guaranteed analysis just can mean there might be less then 1% sodium and therefore it need not be listed. Their list of ingredients doesn't even list a sulfur source. There need not be a lot of sulfur but there should be some. Before using it I would inquire if there is any sulfur at all in their formula. Typically magnesium sulfate would also be used in the nutrient formulation therefore there would be more than 1% sulfur in the formulation therefore requiring them to list the amount of sulfur on their labels GA.

There is nothing in the derived from section that has sulfur in it. I ain't exactly one of AN's PhDs but I know that is no bueno for marijuana.

Also the Ca and Mg would be too low for me in coco.

I am hardly impressed by this one.

you can't have sulfur in a 1 part, because the calcium and sulfur form CaSO4, which is Calcium Sulfate aka gypsum which is abound form of calcium and sulfur. Although the roots are still able to absorb this in this form, it would clog drip system and is not ideal for liquid feeding

How much of Jacks and how much calcium nitrate do you use per gallon?

Also what is the PPM you are shooting for roughly?

Been seeing a lot about Jack's recently but haven't come across these answers...
Also where do you purchase it? A quick google search isn't returning too many promising results


Thanks

jrpeters.com sells it, not sure how you couldn't find that on google and why nobody responded to you but I will!

heres the info I have on Jacks and Cal nit
1 gram of Jacks Hydroponic in 1 gallon of water = approx

N=13 ppm
P=14 ppm
K=57 ppm
Mg=17 ppm
S=22 ppm
Ca=0 ppm

1 gram of Calcium Nitrate in 1 gallon of water = aprox
N=41 ppm
Ca=50 ppm

I use 3 grams Jacks 2 grams Cal Nit per gallon in flower I switch from citric acid down to Phosphorus acid and add 1/4 gram of epsoms per gallon...I use it at 80% strength ...so if you need it for ten gallons mix it for 8 ....I hope this helps ...good luck ...Jabapc
