Did Sunlight Supply Poison Hydroponics Medical Marijuana?
Did Sunlight Supply Poison Hydroponics Medical Marijuana?
A few years ago, professional state-legal California medical marijuana growers noticed their hydroponics crops were showing yellowing leaves, stunted growth, and poor yields. In some cases, entire crop cycles were wiped out.
The growers lost huge amounts of sleep, money and valuable medical marijuana, nearly going crazy trying to understand what was killing their crops. They examined all the factors you’re supposed to examine when you have crop problems: pH, water quality, nutrients, climate control, pests, diseases, plant genetics. You name it, they looked at it.
Through a process of elimination they narrowed the cause down to a toxin called Diisobutyl phthalate (DIBP) allegedly contained in National Garden Wholesale (NGW) ½” Black Flexible Polyvinyl Chloride Tubing. NGW is an affiliate of hydroponics distributor Sunlight Supply, and all three entities are also known or affiliated as IP Holdings LLC.
The hydroponics growers say they had tests run, and conducted tests themselves. Convinced by the testing that NGW tubing was the culprit, they contacted Sunlight Supply and NGW, seeking an explanation and compensation. They got nowhere, so they retained an attorney, Jeffrey Lake. After Lake contacted Sunlight/NGW, he received an August, 2010 letter from an attorney representing the companies. The attorney is named Joshua Stump.
Mr. Stump’s letter offers various attacks dismissing the growers’ claim that NGW tubing damaged their crops. It also contains a troubling section in which Stump says that regardless of whether the growers’ crops were legal according to California law, they were still illegal under federal law. As such, the lawyer claimed, the “illegality” of the medical marijuana enterprise would likely protect Sunlight/NGW from product liability claims.
Stump further hones in on the medical marijuana aspects of the situation by asking all kinds of prying questions about the identity and confidential financial and/or medical history of medical marijuana patients and growers.
Medical marijuana attorneys who examine Stump’s letter say Stump’s approach leaves the impression that Sunlight/NGW is making a veiled threat to harass and/or nark out medical marijuana growers and patients as part of the Sunlight Supply defense strategy should the hydroponics growers file a product liability claim.
On November 22, 2010, Lake and his client plaintiffs (referred to as BT Collective) filed a class action complaint against IP/NGW/Sunlight in San Diego County Superior Court.
During my research about DIBP and other toxins that might enter plants via hydroponics materials, I learned that such chemicals may harm humans as well as hydroponics plants. I also discovered a substantial record of complaints and concerns regarding toxicity problems associated with indoor hydroponics grow tents and chambers made from plastics and other materials.
Beginning in 2006-07, an increasing flood of hydroponics growers began complaining in online hydroponics cultivation forums and elsewhere about off-gassing and poisoning caused by toxins in hydroponics grow tent materials and similar materials. Hydroponics growers told me they’d had problems with indoor chambers made or distributed by HydroHut, Sunlight Supply and other companies.
Reports from growers indicate that of the tent/chamber manufacturers whose customers were complaining about toxic materials, only HydroHut exercised good customer service in seeking to resolve the issues.
In preparation for writing this article, I directly contacted Sunlight Supply to ask them about their tubing and the court filing, and I had previously posted a hydroponics article containing public questions for Sunlight Supply. The only response I ever got from Sunlight Supply was one email from Stump.
But instead of providing the information that hydroponics growers need to know about Sunlight Supply products and the Sunlight Supply customer service and warranty policies, Stump tried to get me to disclose information about myself.
I was leaked what is purportedly a communication sent to hydroponics dealers from Sunlight Supply’s president, Craig Hargreaves, regarding BT Collective’s claims about NGW tubing. I am including the letter in its entirety, because I want to make sure that Sunlight Supply’s version of events is represented fairly. Here is the letter Hargreaves allegedly sent to his retailers:
Craig R. Hargreaves
“I write to you today to discuss a matter pertaining to our Eco-Plus ½ inch black (part # 708235) and blue (part # 708225) branded tubing. Sunlight Supply/NGW has purchased this tubing from a Chinese manufacturer for approximately 3 years now and have sold it without any complaints from our customers. However, we recently received a single complaint from a group called "The BT Collective", a group out of Southern California stating that use of this tubing has caused damage to their crop. When we were first notified of this complaint we requested additional information to help us verify the claim. While the BT Collective responded to this request with additional claims, they failed to provide adequate information to determine whether any of the tubing had caused harm to their crops.
The claim cites that a certain chemical used in the makeup of the tubing, is specifically responsible. To date, we have no credible evidence that this chemical, which is used to give plastic products a soft, pliable feel, has caused any harm to any customer's crops.
Sunlight Supply/National Garden Wholesale has purchased and sold this tubing for 3 years. In this timeframe, we have not received a single complaint from any storeowner or consumer before hearing from the BT Collective. In our experience, when there is a product on the market which is causing plant damage, that problem is quickly discovered. Our customers understandably care a lot about their plants and tend to report problems immediately after they are discovered. In short, we believe that if there were truly a problem with the tubing we have sold, we would have heard about it from customers long before now and from multiple sources. We have not.
Further, when we first started purchasing this tubing, we conducted internal tests by growing plants fertilized and irrigated with water running through the tubing and simultaneously submerged a full 100-foot roll in the reservoir. Our internal tests revealed no damage to the plants.
Sunlight Supply/NGW is a distributor of thousands of different products manufactured by hundreds of different manufactures. Black ½ inch vinyl tubing (the vast majority of sales) is a commodity product both for the industry and us. Sunlight Supply/NGW has no good reason to believe that the tubing it has been purchasing from its Chinese manufacturer causes harm to plants. However, rather than engage in a complex scientific debate, it is far easier for us to merely change tubing vendors.
Out of an abundance of caution, here are the steps we have taken:
Discontinued purchasing from the previous Chinese vendor for the Eco-Plus branded ½ black (product #708235) and blue (product # 708225) vinyl tubing.
Discontinued selling to Dealer Partners these 2 products.
Clarification - The Chinese manufacturer made only 2 of the tubing products (1/2" black and 1/2" blue). No complaints have been received related to any other tubing products in the dealer catalog (page 262).
Changed over to a domestic (USA) supplier on ½ inch black and blue vinyl tubing. These products will now be sold under the Gro-Pro brand name. For inventory clarification, the part numbers have changed. GroPro brand ½ inch black tubing is part #708265, ½ inch blue tubing is part #708260.
All orders now shipping, on ½ inch black and blue vinyl are now made in the USA and have been certified by the manufacturer as, "food grade" and made with only FDA approved materials.
In a good faith show of support for you, our valued business partners, we are offering to take back for credit or exchange (for the USA GroPro brand product) this tubing from any dealer partner wishing to return the Eco-Plus brand ½ inch black or blue tubing. Please contact your local customer service representative with any such requests.
Sunlight Supply/National Garden Wholesale takes our obligation to provide our Dealer Partners with quality, safe and functional products extremely seriously as we have for the last 15 years. At this time, we have no verifiable evidence beyond the BT Collectives claim, that plants irrigated and fertilized through EcoPlus brand ½ inch black and blue has caused damage to plants. However, we felt obligated to inform our Valued Dealer Partners of this matter.
As always, thank you for your ongoing support of our company.
Craig R. Hargreaves, President
Obviously, if you are using an indoor hydroponics pre-made chamber, or thinking of buying one, be sure to ask the manufacturer about toxic off-gassing and warranties. In general, you need to be cautious when using any plastic or other petroleum-based material in your grow room, and do what you can to determine if it might off-gas anything that harms you or your plants.
Please note that Big Mike Straumietis of Advanced Nutrients has repeatedly charged that Sunlight Supply and its allies are amoral profiteers who refuse to respect or acknowledge the medical marijuana community or legal hydroponics medical marijuana growers, but they do like to make tons of money selling them hydroponics products.
You’ll note for example that in the Sunlight Supply letter you just read, Craig Hargreaves offers only to reimburse “dealer partners” (retailers) for unused NGW ½ inch tubing. He makes no offer to reimburse growers who say they’ve lost tens of thousands of dollars worth of medical marijuana crops because of that tubing.
“The issue of whether NGW tubing poisoned crops will be explored scientifically, I hope. What worries medical marijuana growers is a big hydroponics company that responds to a warranty issue by hiring a lawyer who hides behind medical marijuana being illegal federally,” said a hydroponics grower not affiliated with BT Collective. “We already knew that Sunlight, Hydrofarm, Maximum Yield, Urban Garden and the rest of those types are hypocrites who won’t allow any mention of medical marijuana growers at their trade shows and in their magazines, even though medical marijuana growers are a majority of hydroponics customers. But when Sunlight Supply uses federal marijuana law to shield itself against claims from hydroponics growers whose crops got ruined, that’s worse than hypocrisy.”
