Warning new off gassing product!!!!

[Kcar]

I had one of these hoses and my first couple runs with it (About 12") I had
undiagnosed yellowing. When all the bad crap finally leached out, all was well,
but the hose got hard as shit, and I broke the fittings off my pump like 4 times.
Finally got a new piece of hose.It said N - G - W on the side in white letters.

[stonedwarrior]

having a similar problem, although I am not using any tubing whatsoever... Mylar and wood are the only 2 things in my growroom.

And it only occurred on SOME plants... what the?
placed new batch of seedlings in the clone/veg cab,
put a few shithouse bagseeds in the cab with new pots, hoping that will help me dignose if it was them, otherwise im stuffed....

anyone have any other suggestions?

 

[Bennyweed1]

Is diisobutyl found only in soft plastics? My plants show the same signs as the plants in your photos. I replaced my entire tent last weekend because it was the only thing that remained from my original setup. Now that I think of it though, I have two 16" fans in there that are also from my original setup. Could the plastic the fans are made of contain diisobutyl?

Im 6 months deep into this problem and not until a week ago did I find out it is something offgassing....Thanks snoopy!

 

[snoopytime]

Yess SIrrr! Generally it is soft plastics, but it can be in weird shit too . . such as . . PIZZA BOXES!?!?! no kidding, there really is DIBP in cardboard pizza boxes. So, you never know what it could turn up from.

Fuck my pizza-box cab build now...

Three years of planning gone to waste.

(I only pretend to joke: I lost mad shit to this fucked up tubing!!!!)

my leafs
looked just like the one in threadstarters post.
textbook
had two of these basins in the room.
these 2 things
affected every plant in the room.
12 in total.
i hope i got them cans out of the place fast enough.
food grade plastics from now on
if any

thank you to the thread starter.
without this thread i still woulda been trying to figure out what bad thing i was feeding
my plants and praying to the god of cal-mag for pale leaf to turn strong green.

Thanks for the heads up. Sounds like the toxicity issue.

I suspect anything plastic or rubbery now. I removed all pots even and went with smartpots. I looked into my bontanicair flood tables and those are ok. Thats about the only thing I trust.

 

[rambo6372]

I am so thankful UGU for making this thread. I have been hit with this offgassing and couldnt for the life of me figure it out. Youve done all the leg work and I cant think of a way to express my appreciation for what youve done. This has answered all my questions and I will be purchasing a new set of tubes immediately. THANKS THANKS THANKS.

Medical pot business wants court fight secret

Medical pot business wants court fight secret

At first glance, the lawsuit filed this year in federal court in downtown San Diego by BT Collective appears to be nothing more than a dispute over allegations that one business sold faulty products to another.
But a closer look shows the suit, a potential class-action case, is more than that — one where a pursuit for secrecy by both sides earned the ire of a federal judge and which illustrates the conflict between state and federal law over medical marijuana.
BT Collective is a medical marijuana operation in San Diego that opaquely describes itself in the lawsuit as a manufacturer of “natural and organic health care plant products.” It filed suit against Sunlight Supply, a Washington company that sells indoor gardening supplies, blaming the business for selling black flexible irrigation tubing that contains a toxin that ravaged and wiped out the collectives plants.
Last week, both sides requested to file under seal Sunlight Supply’s motion to dismiss the case, as well as all of its exhibits and any further legal briefs from either side.
The reason: The documents would touch on “sensitive matters pertaining to criminal liability due to differences between state and federal law.”
In other words, they would be talking about cultivating marijuana — legal under California’s medical marijuana law but illegal under federal law.
U.S. District Judge Larry A. Burns would have none of it. “BT Collective is more than welcome to bring this case against Sunlight Supply, but it cannot expect the Court to insulate it from the collateral consequences of doing so,” he wrote Tuesday.
In a sharply worded three-page order, Burns said the collective was trying to fly “under the radar of federal law enforcement.”
Earlier in the case, both sides agreed that the deposition of BT Collective CEO Travis Yost would be taken under seal, citing the same federal-state law concerns.
That request was granted by a different judge, but Burns wiped out that order, too, saying the deposition is not in the case file and the witnesses avoided any criminal issue by “vigorously asserting their Fifth Amendment rights in response to questioning.”
The collective now has two choices, Burns concluded. “One, it can litigate the case with total transparency and roll the dice that the United States does not file criminal charges against it,” he said. Or, it can drop the suit.
Yost did not respond to a request for comment. A lawyer for Sunlight Supply declined Thursday to comment on the case. The company has denied its products are responsible for the marijuana collective’s problems.
BT Collective filed papers Wednesday asking Burns to stay his order while they appeal the issue to the 9th U.S. Circuit Court of Appeals.
Jeffrey Lake, a prominent medical marijuana lawyer in San Diego who represents the collective, said the secrecy is necessary because both sides “should have the right to litigate a civil matter without fear of criminal prosecution.”
The case was initially filed in state court, Lake wrote in an email, but was moved to U.S. District Court by Sunlight Supply because federal courts have jurisdiction over cases between people or businesses in different states.
Lake said that move was part of Sunlight Supply’s legal strategy and raised a larger question — whether one side in a dispute “can take advantage of a conflict of laws by changing jurisdictions in order to subject an opposing party to potential criminal liability.”
Alex Kreit, a law professor at Thomas Jefferson School of Law in San Diego, said the case illuminates the vexing position that medical marijuana providers are in.
“The difference between state and federal law puts those medical marijuana collectives in a tough position,” Kreit said.
Other businesses can go to court to settle a dispute, but medical marijuana collectives have to think twice because it may expose them to scrutiny by federal law enforcement, he said.
“Just the possibility of federal prosecution carries a lot of downsides,” Kreit said. “It makes it more difficult for the collectives to pursue remedies if they are defrauded or sold a defective product.” The conflict between state law that allows medical marijuana cultivation and federal law that does not and considers all marijuana to be an illegal drug is normally played out in criminal courts, Kreit said. Collectives and cooperatives operate knowing that federal prosecutors could take action against them.
Even so, the broad request for secrecy in this case was not warranted, said Peter Scheer, a lawyer and executive director of the First Amendment Coalition, an open government advocacy group in San Rafael. “My first thought is the judge is right,” Scheer said. “When you file a lawsuit, it is inherently a public matter, and there is good reason for that.”
Scheer posed a similar scenario of a lawsuit over the copyright to computer software that allows someone to avoid paying taxes.
“I don’t think you could go into court and expect the court to seal all the documents to protect you from the prying eyes of government authorities,” he said.
He also said because BT Collective’s suit is about an allegedly defective product the case could have broader interest for other businesses and the public. Keeping that information open is a crucial consideration, Scheer said.

I do not know much about the law, however it seems to me that cannabis growers are not legitimate enough, within the legal system, for a court case like this. The best way forward is to find a grower of legal crops who has been damaged by this product and enter them as the plaintiff in this case.

Does Sunlight Supply still distribute this shit tubing?

 

[PoopyTeaBags]

they changed there tubing however i will never buy there shit again. They sent the feds after u.g.u and knew that there shit was fucking shit up.. . they know the proof there are tons of cases right here on ic mag and they deny it. Then they told him if he trys it then they release the feds on him....


sure as shit 3 months or so later boom... sunlight is a fucking shameful ass company... Threatening the MJ growers saying thats not what there product is intended for knowing damn well its 95% of there business... ive boycotted sunlight ever since....

 

[1and1]

Thanks man, Yeah some NW distributor has been telling me of the evils of Sunlight Supply. I hate their sketchy ass yield master hoods. Oh whoops the glass fell out

uote=U.G.U;3851657]Warning new off gassing product!!!!

--------------------------------------------------------------------------------

So I have been experiencing a mysterious yellowing for about 10 months. Every thing that went into one of my 11 different rooms (some that had been going 5+ years) started to yellow and eventually die. My first instinct was my ph I checked my pens, they were not very far off but I calibrated and bought new probes anyways. That did nothing. Then we suspected the nutes, maybe we got a bad batch. I had bought 6 gallon jugs and filled all my 1 gal’s up off the same batch. Call the company run the batch numbers and they say they are 18 months old, So we went out bought new nutes and nothing changed. So after that I figured my favorite brand had fallen off and we decided to try another brand. We go buy $1000 worth of canna. And we thought possibly it could be something with our clones so we picked up a batch of clones from an LA club. Same thing new nutes new genetics same yellowing. So now I am scratching my head start making some calls visit a bunch of other rooms, and at least 20 in my immediate area have this same mystery problem. So I do some research find out we are all on the same water supply. I found 4 rooms on another water district doing bitching so I say BINGO, It must be the water. We go out and buy a 275 gallon tote and start buying water from this other district. A real pain in the ass I might add we had to do 2-3 trips a week to meet our demands. Same problem. We start doing testing 1st water test, 2nd tissues sample, I have a horticulturist come and look at things. He suggests an Iron def. We get our tests back everything looks good. We do a tissue sample off a room that is doing good compare our results and everything is fine. Except my plants still look like shit. So I emailed my test results to my original nute company they pass it around the office and let everyone take a look at it. I get a call a couple of days later from them and he asks me if I have ever considered off gassing. What is crazy is the night before I found a thread on the hydro huts and was showing my partner how Identical it looked. So now we go to our rooms and start looking around at what it could possibly be. Like I said some rooms had been going in the same location with nothing changed in about 5 years. There is only 1 new product that we had replaced the ½ tube that connects all the buckets. I started to call around and every room that was having the problem had replaced there tube with the new stuff. The 4 rooms that were doing good were using old hose and was just washing it out. So being lazy saved theses guys who would of thought. I have been talking to the company that made the offending tube for 4 months and they do not wish to resolve this problem even though I have proof that the toxic chemical is in the tube. We have done GC/MS testing, LC/MS, testing and FT IR testing that show conclusively that the chemical Diisobutyl phthalate is in the tube. This is the same chemical that caused the problems with the hydro huts. If you are having a mysterious yellowing and are using NGW tube replace it immediately and please respond to this thread. I am going to be working on a class action against these guys. I have some of the worlds top experts on the matter willing to testify and do any research needed to win this case. The idiots printed there names on the tube it has n-g-w.com printed every foot, so it is easy to identify.


Here is a brief description of what the phthalate does to the plants.

The toxicity caused by a volatile constituent from certain samples of flexible polyvinyl chloride (PVC)
was due to dibutyl or diisobutyl phthalate (DBP or DIBP) plasticisers. It has caused serious financial
losses in the horticultural industry. The two phthalate esters have low volatilities, so any toxicity lasts
for many years. Radish (Raphanus sativus L. cv. Cherry Belle) seedlings, exposed to an air stream
containing 160-180 ng dm~3 of butyl phthalates developed chlorotic leaves within 3-4 d and died
within 12 d. Neither dioctyl nor diisodecyl phthalate (DOP nor DIDP) produced damage in the test
plants. Measurements of photosynthetic and respiratory gas exchange in intact shoots of affected
radishes showed that photosynthesis was severely inhibited whilst respiration was virtually
unaffected. Electron micrographs of sections from young leaves showed disruption of thylakoid
formation and granal stacking. In mature leaves, thylakoids and grana were well formed but
chloroplasts were swollen and the thylakoids were pushed towards the vacuolar side of the
chloroplast. Sensitivity to toxic phthalates varies between species; all members of the Crucifcrae tested
were susceptible, tomato less so, and lettuce and ryegrass were resistant. Toxicity of DIBP, from PVC
glazing strip, caused a reduction in crop value of £20000 per acre per year in commercially grown,
monocrop tomatoes.




The effects of phthalate esters on chlorophyll a2 fluorescence in radish plants (Raphanus sativus L. cv.
Cherry Belle) were examined Fluorescence yield was increased in those plants exposed to an aerial
concentration of 120 ng dm"3 dibutyl phthalate (DBP) at a rate of 3-0 dm3 min"1 for 13 d.
Comparison of fluorescence enhancement ratios and Fr^/F01 suggests that DBP inhibits photosynthesis
in radish plants at a site after QA. Both DBP and diisobutyl phthalate (DIBP) strongly
inhibited uncoupled (PS2 + PS1) electron transport rates in thylakoids isolated from spinach. At a
chlorophyll concentration of 10 /ig cm"3 the concentrations of DBP and DIBP exhibiting 50%
inhibition were 44 mmol m " 3 and 42 mmol m " 3 respectively. Basal electron transport rates were also
inhibited, with 87 mmol m"3 of DBP or DIBP producing 50% inhibition. Measurement of
photosystem 1 activity suggested that the main site of action of these phthalates was localized at a site
near the reducing side of photosystem 2.

came across this post and was Gratefully Blown away ! WOW ! Amazing ! Bravo to you,
for award-wining research !
So, this is why i posted my question about my reservoir water / nutes ?

Im getting ready to fire up an ebb&gro..Is there a safe brand of 1/2' tubing yet?

 

[gus738]

hi u.g.w i started reading page 27 and now . i will get back to the whole thread but first of all let me thank you because you did something great for alot of people, right down to the fact that it can be harmful to humans. . . .

that being said is the c.a.p ebb n grow 12 bucket 2 gal hydro system n.g.w? the hoses it comes with is black and it also has 2 strips of clear and blue . i was putting the grommets on the buckets and then stop because dont know if the tees or elbows etc i needed help from here on . but

now im wondering if this tubing is bad?
