Hydro nutes cleaner than some organic?

[ScrubNinja]

Hello, I grow organic and chem so I would like to state that this is not a troll attempt or anything like that. Just an honest question about health.

Over on the nutrients part of the forum, there is a great thread on heavy metals in nutrients. As far as the hydro nutes go, I have been using Dutch Master since I started and I was pretty amazed to see they are about the cleanest chem nute there is. Apparently they use british pharmaceutical grade stuff etc.

So my question is, if the dutch master has metal levels so low they can't be measured, is the resulting weed better than from a grow using organic nutes that do have metals in them?

I realise that not all organic stuff has metals but I know some of the stuff I've used has. I also realise that to make those pharmacutical grade ingredients for the DM probably just created more pollution in some other way. To sum it up, the question is about the resulting weed and how safe it is. Perhaps there are other issues I've not taken into consideration. Thank you

id be more worried about the high levels of heavy metals in the air you breathe before your buds.

Soil – farming system – food – health: Effect of conventional and organic fertilizers
on heavy metal (Cd, Cr, Cu, Ni, Pb, Zn) content in semolina samples
Soil & Tillage Research 107: 97-105.

"Ten durum wheat cultivars were cultivated during two consecutive years in the same area following
both conventional and organic farming systems (CFS and OFS, respectively). The content of six heavy
metals (i.e., Cd, Cr, Cu, Ni, Pb, and Zn) in soil and semolina samples from 10 different wheat cultivars was
assessed, and the effect of conventional and organic fertilizers on these heavy metal contents evaluated.
Although significantly higher heavy metal input to soil was provided by adding the organic fertilizer,
semolina samples obtained from the cultivars grown in CFS were richer in Cd (82 mg kg-1 vs.
18 mg kg-1), Cr (182 mg kg-1 vs. 50 mg kg-1), and Cu (6.6 mg kg-1 vs. 5.8 mg kg-1), thus suggesting a
potential for the organic system to reduce the amount of these elements in the soil solution, to limit their
availability and uptake by plants, and to influence their translocation processes to grains. On the other
hand, semolina samples obtained from OFS showed higher concentrations of Ni (295 mg kg-1 vs.
166 mg kg-1), Pb (94 mg kg-1 vs. 82 mg kg-1), and Zn (13.6 mg kg-1 vs. 10.8 mg kg-1) with respect to
those obtained from CFS."

I pretty much assumed/had faith that what MrFista just posted was the case. I believe an organic system has its way of dealing with toxins. I also believe my body in itself is an organic diverse probiotic ecosystem that will deal with any toxins I may be exposed to.

Nature's solution to pollution is dilution. She has a way of evening things out.

What I would interject is that a commercial nutrient called organic and certified as such by OMRI does not necessarily make it truly organic or natural. To me organic/natural is a system or growing method rather than a class of inputs.

Good question.

It reminds me of the organic section of a supermarket.

Here in Oz it is still a disgrace and the 2 big chains will try and sell you overpriced bags of questionable oranges, apples and maybe some beetroots and broccoli. Usually they dont sell and just sit there going off. They may not have been any good in the first place and defo not worth double the price of the regular stuff... my point is organic doesnt automatically mean better. I have had bland, tasteless and rubbery oranges and broccoli marked organic and fresh, tasty 'regular' stuff.

If i go to the specialist organic/wholefood place i can pick up locally grown organic fruit n veg that is usually top quality and will last for ages and taste great. Pity its 2 hour round trip...

Having said that Tesco supermarket in the UK was a revelation for organic produce. Loads of it, great quality and fair price...

Certification is the way to go but too expensive at mo.

I have no problem using a bit of cannazym or house and garden coco nutes every now and then. Coco can be a bitch to go 100% organic.

Nearly all my inputs are natural.

Heavy metal absorption increases as medium pH drops. Elemental calcium, potassium, magnesium and sodium are metals. The 'bad' ones would be more like arsenic, cadmium, lead and mercury.

No problems really if growing organic in soil.

Hydro nutes are not cleaner in the end.
