I would debate the grow performance.

A chemical compound is a chemical compound. Doesn't matter if someone gets nitrogen from steer manure or other chemicals it is still the same compound in the end.

 

[Douglas.Curtis]

altho NPK is NPK....
sources of those nutrients matters, read your "derived from"
def packaging and marketing plays into the cost, but so does the quality of the inputs

When you're working with plants great at phytoremediation, you really want to pay attention to what's in there cannabis doesn't need. Excess and completely unnecessary elements are readily absorbed by cannabis.

Cadmium is a prime example. Sample analysis has revealed unhealthy levels of cadmium, from cannabis grown in "Cadmium Safe" soils.

so you don't think there is any difference between ammonium nitrate and calcium nitrate?

sources of N are not all the same, altho ALL N will make plants green, they are not all the same
in organics alfalfa meal and/or blood meal are both N sources that can be readily available and may burn plants with excess N, so it helps to use different sources that become available at different times (some quick release, some longer term - SAME reason many farmers use a mix of calcium nitrate and ammonium nitrate)

as for grow performance, different sources will be more applicable in different settings (peeps growing in a bedroom/basement/tent won't have the same solutions as peeps working fields on farms)

I was thinking in terms of hydro, liquid nutes, chemical mixtures and what the chems were brewed from.

After looking at ammonium nitrate and calcium nitrate I realize that nitrogen and nitrogen fertilizer mixes are more complex then I originally thought.
So thanks for the morning food for thought. I only like to debate things I think I might learn from.

good vibes, def alot more to fertilizers than hydro companies would let you know

i'd love to do some tests on the hemp from my field... see what levels of these heavy metals are in them
any info about a lab to do these tests?

Wouldn't it be nice if the current 'required' testing included this information? I mean, who doesn't want to know the heavy metal content of their cannabis/hemp? Excluding those using the material for hempcrete and similar applications anyway.
lol

Unfortunately, I do not have the information on labs that I would like either. Anyone happen to have that info readily at hand?

 

[Lost in a SOG]

You want any lab that does Mass Spectrometry on plant material, that will detect all the metals..

Cadmium is also really high in coffee, tea (camilia sinesis), tobacco and chocolate.

Cadmium like many toxic metals locks out several majorly important cofactors essential for life like zinc and other elements with the same charge and affinity as cadmium.

The reaction a body has to cadmium once it is already toxic in it is like a drug which partly explains the abuse of these plants that are high in it excluding cannabis because it is significantly lower in cadmium and shows less of an affinity for bioassimilation of Cadmium than other metals. I remember reading a paper on it.

 

[jidoka]

So in these papers...any citations, what was the health of the plants, what was pH, what was the fungal load of both plant and soil, how much humus in the soil, did the writer have a motive, has there ever been another study that backed it up.

Call the dept of ag. Tell them you would like to test for Cd. They tend to be very helpful

If you wanna test a drug strain phytatech is it for licensed facilities. Hemp may have more options

Acting like shit is true on hearsay is bullshit

 

[ColoSpringBudZ]

Shake it jid

 

[Douglas.Curtis]

All of the reading I've done on the hyper/dynamic properties of cannabis came from studies on phytoremediation. I don't keep links or logs of my reading, you'll have to do your own searches. No, none of them were on cannabis boards. lol

Shit is still true, regardless of whether or not people remember where it came from. lol Back yerself up and open a case of internet research. You know what to look for now.

 

[Lost in a SOG]

Not knowing the reference ranges personally but knowing the guidelines generally applied to these things by gubmints "Cadmium safe" soil in this day and age is probably often still toxic i would imagine.

The issue with cadmium is that it's way too high in people anyway. If they did some herbal liver detoxing like Dr. Schultz protocol then a billion toxic white people would live a bit longer and be a bit less righteously angry as well. Cadmium is totally an elephant in the room for health in the western world. I'm not fear mongering I did my own research whilst doing a herbal degree, I also never bookmarked most of the 1000s of studies I had to go through.

people could try Mycoremediation on their soil and get rid of the mushrooms after they have accumulated the heavy metals..

 

[Rodehazrd]

using the correct terms I didn't have to look far for info on using hemp to clean heavy metal contamination. Here's a link to a news story in europe downwind of a steel mill.
https://www.cbsnews.com/news/cannabis-plant-soil-decontamination-italy-vincenzo-fornaro/
The first thing I think of is all the trace amounts in Kelp, Marl and Aragonite. Are we splitting hairs here or looking at a real danger?

 

[Lost in a SOG]

Imo splitting hairs unless you're maybe growing on ex industrial land or using horrifically contaminated soil or water for some reason in which case your smoke will maybe be getting on for possibly as carcinogenic/toxic as tobacco or a highly processed ready meal or going for a bike ride in a busy traffic congested city.

let's face it all smoke contains free radicals and heavy metals.

 

[Douglas.Curtis]

With most plants I'd say splitting hairs. With cannabis, it depends on how much of the end product is used by someone and how often. I'm a 24/7 edibles and smoke consumer, so cannabis with even a slight problem is ridiculously apparent.

Always avoiding the question. Never have your own data. How you know there isn’t Cd in your weed...you wanna say how can the “industry” sell w/o knowing. Look in a fucking mirror. Every time you get questioned there is always some kind of excuse why you don’t know

I recognize pure bullshit when I see it

Always the same. You don't like it when someone doesn't have a specific answer, so you want to attack character and make excuses for yourself. I never once mentioned not having Cd in my cannabis. That was never the topic at hand here, everyone is aware of this.

I recognize attitude issues when I see them.

Word on the street is this place will test for the public.

Smoke'em if you got'em.

 

[Douglas.Curtis]

That's progress.

When you run those tests DC make sure to include Al. My attitude problem wants to know
