The plants with the small root mass that you were disappointed in, did you by any-chance defoliate them when they were young,and were you hand watering them at the time.
Guys.........gotta think about what those walmart bags are made of , or rather where they came from........Chems leaching into yer rootzones from chemical reactions between containers and feedjuice ain`t a good thingy.......
He was then flamed by certain forum members, for being a tree hugging, tofu loving,scare munger.
Now forgive me for being a bit anal,but i made a couple of calls to a few overseas colleges regarding the chemical leaching of agents in pp/or if possible any cases of contamination in agriculture.
I was pointed to a study conducted by the university of Alberta who in 2008 published a strong warning about leaching chemicals from plastic that they stumbled upon quite by accident.
The medical researchers caution that two chemicals leaking from plastic laboratory equipment were so biologically active that they ruined a drug experiment.
What makes the discovery so compelling is the fact that the leaching was happening from one of the most widely used plastics in the world—polypropylene. Yes, you'll find the stuff in lab beakers. But you'll also find it in clothing, in yogurt tubs, And wally bags folks.
It should be noted that the warning was a heads-up to the scientific industry that they will have to carefully monitor any experiment carried out with polypropylene containers, given the possibility that two chemicals leaching from the plastic could have the same, experiment-ending effects as that found at the University of Alberta.
The warning was not meant as a health warning.
And not enough is known about the two chemicals found to be leaching.
BUT
chemical no 1. quaternary ammonium biocides.
chemical no 2. oleamide.
but biocides themselves carry a Hazards and Environmental risks.
Because biocides are intended to kill living organisms, many biocidal products pose significant risk to human health and welfare.
The use of biocides can also have significant adverse effects on the natural environment. .
Disposal of used or unwanted biocides must be undertaken carefully to avoid serious and potentially long-lasting damage to the environment.
Quaternary ammonium ions.
can cause skin and respiratory irritation. They are thought to be the chemical group responsible for anaphylactic reactions that occur with use of neuromuscular blocking drugs during general anaesthesia in surgery.
Oleamide. is an amide of the fatty acid oleic acid. It is an endogenous substance: it occurs naturally in the body of animals. It accumulates in the cerebrospinal fluid during sleep deprivation and induces sleep in animals.
It is being studied as a potential medical treatment for mood and sleep disorders, and cannabinoid-regulated depression.
The mechanism of action of oleamide's sleep inducing effects is an area of current research. It is likely that oleamide interacts with multiple neurotransmitter systems.
Oleamide is structurally related to the endogenous cannabinoid anandamide, and has the ability to bind to the CB1 receptor as a full agonist. In addition, oleamide potentiates several serotonin receptors and the GABA(A) receptor, and inhibits gap junction communication.
Synthetically produced oleamide has a variety of industrial uses including as a slip agent, a lubricant, and a corrosion inhibitor.
Since polypropylene is used in a wide number of food containers, the problem is being studied.
There is no documented evidence of Oleamide being used specifically as a recreational drug. However, it was found in large quantities in "Skunk" alongside the synthetic cannabinoid JWH.
Oleamide, occurs naturally in the human body, and is found in the brain and blood.
The question then, is what happens when humans are exposed to more of this chemical than that which is normally found in the body? Thus, it's not the presence of oleamide, but the amount.
some of the information above can be found by searching the archives of Canada's national newspapers The Globe and Mail.
And the chemical information is from a paper submitted by the university of manchester in England on behalf of a drug company called Astra Zenica.
So what may of just been a friendly forum warning could imo be worth taking note.
