Anyone know Molasses breakdown?

Anyone know what 5ml/gallon of Molasses would be PPM wise? NPK CA NG S ? been searching and cannot find

If you are using a horticultural molasses then sulfur would be a key ingredient. Other than the feeding of microbes than I don't believe it has any other nutritional value to the plant. I would also think the ppm value would be really low. I use horticultural molasses also as a ph down and every time I water.

Looking at the side of the Jar 15ml is
15mg sodium
150mg potassium
15g carbs
40mg calcium (4% DV)
.75mg iron (4% DV)

how would that convert to PPM? for my Cannastat calculator

There can be a good amount of soluable magnesium and several other micro/macro nutrients. It is variable due to differences in sources i.e. cane or beet..... Processing methods and levels of refinement vary as well.

Use the site search someone has provided the 3LB's very informative molasses write-up. There is an extensive thread on it.

c'mon dude that's easy. put forth a little effort! Elbow grease?

google search convert mg to ppm

multiple conversion calculators and this thread in which physicists from Los Alamos explain it, all on the first page of results

http://www.convert-me.com/en/bb/viewtopic.php?t=437

1 mg = 0.001 grams
1 kg = 1,000 grams

0.001 / 1,000 = 1/1,000,000 = one part per million

All you need to do to convert is take "mg/kg" off the end, and stick "ppm" on.​

sweet so 5ml a gallon of grandma's blackstrap gives me roughly

13ppm potassium, 3.5ppm calcium, 5 grams sugar

too bad the label does not state the magnesium

Huh?

To get PPM...you have to mix it into something. 15ml mixed into a liter is a whole different PPM than 5ml mixed into a swimming pool.

Sorry that didn't have your answer. However, I think it varies by souce and production technique. I am open to correction on that. Seems like taking the label info and calculating is maybe best. I just use it as an additive in organics and try not to over apply.

Have fun and best regards.

nutrient profile/npk - molasses, fnb, etc...

nutrient profile/npk - molasses, fnb, etc...

DonkDBZ said:
A few people asked the PPM breakdown in that thread but no one answered.

But I guess I should have used google like carl did instead of yahoo
searching wont work.
have to do the math. & convert values. *mistress* did so, here

calculating npk/nutrient profile

the generic npk is roughly:
1-0-5 npk (molasses)
though there is phosphorus there in small amount.

this should provide all data required.
& formulas on how to calculate the profile on any fert &/or foodstuff, by using nutrition facts on label.

example (link):
wholesome sweeteners organic molasses:
per 1 tablespoon/22 g, in 1 gallon of water/3.785 liters:

potassium: 730 mg/~20% of 3500 mg dv for k/730/3.785=192.86 ppm

calcium
: 115 mg/~10% of 1000 mg dv for ca/115/3.785=30.38 ppm

magnesium: 8% of 400 mg dv for mg/.08*400=32/3.785=8.4 ppm

iron: 15% of 18 mg dv for fe/.15*18=2.7/3.785=0.71 ppm

*vitamin b6: 10% of 2.0 mg dv for vit b6/2*.1=.2/3.785=.05 ppm

*sugars: 10g

*total carbohydrates
: 14g
enjoy your garden!
 
Why are you curious of yer PPMs off molasses?

I use Honey ES (molasses based product) in my bloom feedings and I must say, I will check the EC/PPM after all nutes are in and then again after correcting pH.....and the Honey adds very little (maybe .1 - .2 EC) to the mix.

IMO, these PPMs don't really need to be factored into the whole equation.

I used to be all wrapped up in what my PPM was. I own a Truncheon and do use it, but these days its more to reproduce results than a walking stick.

Sometimes you can see really high PPM numbers and the plants jam. Other times you see low PPM numbers and your plants are burned. Every plant is different and so is every nutrient in the sense of how the plant uses it.

So, add molasses at 1 tsp per gallon IMO and carry on.

I am running modified H3ad/Rez in Coco. I don't wanna deal problems from throwing my ratio's too far off. Plus work is slow and I have nothing better to do then read on the internet all day.

And ever since I download that Damned fun to play with nutrient calculator from Cannastats I keep messing with my nutes all the time.

But when I was making new mom's I lost the sheet telling what was what so I had to dump em. I can get em all back but my 8 week Jock Horror I grew from seed. She was my control subject for all my nute experaments

if list nutrition facts label #'s...
have to convert daily values(dv%) to ppms, then can get millimhos, ppms, or ec, etc...

molasses has 3 separate physical properties:

sugar matter
soluble carbohydrates (disaccharide and monosaccharide hexose sugars). mineral matter tends to hold sucrose in solution, so it is the balance of reducing sugar and mineral matter that determines the theoretical yield of sucrose from sugar cane. the residual syrup is very often referred to as blackstrap molasses.

non-sugar organic matter
non-sugar organic matter of molasses accounts for many of its physical properties, in particular viscosity. It consists mainly of carbohydrates, such as starch, nitrogen compounds (which gives beet molasses its earthy flavour and smell) and organic acids.

the proportion of crude protein in standard cane molasses is very low averaging about 3-5%.

crude protein/6.25=nitrogen content...

although crude protein is primarily listed on feed grade (livestock) molasses, some food grade (human) also have protein content listed.

there is also a significant quantity of organic acids in cane molasses, the major one being aconitic acid. molasses also contains volatile fatty acids averaging about 1.3%.

the acids may help maintain ph-stability... major component of gh's bio-thrive line. molasses chelates micro-nutrients in organic shell until planty can uptake/exchange elements.

mineral matter

calcium - up to 1%
potassium & sodium (as chlorides)
magnesium
sulfur
copper ~7ppm
zinc ~10ppm
iron ~200ppm
manganese ~200ppm

b1, b6...

molasses ~ npk [(kg/l)/3.785=~ppm per gallon)

ph - 4.2-5.0
nitrogen kg/l - 0.45-1.60
phosphorous p205 kg/l - 0.10-0.29
potassium kg K2O/L - 3.74-7.83
calcium kg CaO/L - 0.45-5.18
magnesium kg MgO/L - 0.42-1.52

1.025[n] - 0.195[p205] - 5.785[k20] - 2.815[ca] - 0.97[mg], or...

1-0-5-2-1 npk-ca-mg
