Health and Environmental Information

https://www.phthalates.com/index.asp?page=5

The latest research findings and current understanding of the health and environmental effects of phthalates clearly show that they do not pose a risk to human health or the environment.
It is now scientifically accepted that the carcinogenic effects produced by phthalates in rodents are species specific and of little relevance to humans. The environmental impact of phthalates is considered to be low due to their ready biodegradability and low toxicity.
Plasticisers in general and phthalates in particular are currently the subject of considerable media, legislative and scientific debate. This is not new. Concerns regarding plasticisers have been raised on a variety of topics at regular intervals ever since the early 1980's. These have included carcinogenicity, environmental effects, oestrogen mimicking, phthalates in toys, and most recently exposure via medical devices. However, any fears have repeatedly been shown to be unfounded.
Plasticised PVC has been used for more nearly 50 years without a single known case of it having caused any ill-health and the environmental effects of phthalates are known to be minimal. Academia and industry have continually worked together to address the concerns and conduct necessary research. Indeed there is more known today about phthalates than almost any other chemicals.
Unfortunately, politics play an increasingly important part in any debate relating to chemicals but, in the majority of cases, a scientific approach to the concerns has been adopted by the authorities.
Indeed, it is as a consequence of the large amount of scientific research that has been carried out and also because flexible PVC makes such a valuable contribution to modern life that plasticiser usage continues to grow.
EU risk assessments, conducted under the Existing Substances Regulation (793/93/EEC), have now been published for three of the five main phthalate plasticisers (DINP, DIDP and DBP) and those for the two others (DEHP and BBP) are almost complete. For DINP, DIDP and DBP there are no risks identified for any application in which they are used. In the case of the risk assessments still being finalised it has already been agreed that the general population is not at risk from the use from either plasticiser.

The main post has been updated with information from both Homebox & Hydrohut. Worth a look as some thorough information has been provided.

neuroherb · 01-15-2009, 03:43 PM

As mentioned I have been provided with a Homebox and will be running a test grow in it. From putting the tent up initially I can see the material for the skin is a lot different the Homebox material feels thiner and also has a feel of laminated materials rather than a canvas which has had a liquid plastic bonded to it. There was no plastic smell, which was very prominent in the other tent I had.

The zips are of better quality running smoother and actually light tight again a big diference as my previous tent looked like one of those luminous skeleton suits you get at halloween.

It is a Homebox XL version 4, a full grow test will be posted on it with pics in a few weeks.

Just to be clear any tent I name in comparison to this Homebox is a no name brand I got on an auction site not a previous Homebox or a Hydrohut.

looks like Mr Bongjangles has already helped you good, but it's a good possibility as you removed the bottom white liner the problem might clear up. If it doesn't please keep us informed as the new silver lining is meant to be a solution. If it has problems of its own it would be good to follow them and you are not the first to ask about one.

Thanks to a couple of folk here for dropping by and getting involved even if it has been heated at times, good to know that discussion on topics as important as this are taken seriously by people centraly involved. However the forum site here has general rules on naming people given the general topic so we have to observe this an be a bit careful.

Getting past the heated discussion and starting from the premise the brands being discussed do not or no longer sufffer from this issue. What would be the thoughts on getting together with others of similar safe standards in the market sector and developing an agreed mark / symbol to signify the product has been tested for reactions such as toxic tent syndrome?

All sounds good, but you're talking about being polite and yet one manufacturer even went as far as copying a logo, yet did a crap job of copying the rest of it. I dunno man, I think the gloves were off at that point and it's a bit pathetic, don't you think?
I'm surprised in fact that homebox didn't sue the arse off of them, that's what I'd have done.
People should be aware of who they're dealing with and their level of ethics, you'd have to get a mark agreed at EU level or at least at national level in some country, I think the safety standards that homebox stick to would be good to go by, I mean if you can't find an indoor grow room standard then surely a standard for childrens toys which will end up swallowed, chewed and in mouths would be a good one.
Maybe go by those standards which already set the bar pretty high?

Hmm I am a new medical user doing a first time grow and I was considering building my own grow tent with a PVC frame for mobility and to save moneym is this going to cause the same issues If I just use the PVC for the frame and the frame itself is wrapped in plastic similar to greenhouse plastic? Ive yet to purchase my products so I just need some input before I go out and purchase anything. These plants will be my medicine so if they have problems I will have dug mysekf a large hole, Id planned on going shopping this week so if someone can help me out soon Id really appreciate it.,

Try the grow room design forum, they'll be better at answering that question there I'd have said.

Hi Gary

If you were to follow the link in the info given by Hydrohut https://133.5.207.201/ijob/Biotronics...V13_p39-42.pdf

In it the last paragraph on the first page discusses the problem occurring in glass greenhouses with a PVC cushion strip. It depends as presumably your PVC poles will not be that flexible and the issue does seem to be arround the use of plasticisers which make PVC flexible.

However if it was me I would look for a diferent material.
