Yes, They're are a very good way of removing pests, This is not what I am trying to get at. This is already known. And no where in this thread have I said they were harmful to plants. I say that they should NOT be used on flowering plants for a simple reason, You are putting trace amounts of carcinogenic chemical residue on your harvest. You probably dont notice, but it can't be very healthy.

I am simply trying to set a warning that can be viewed by all so that they know what they are dealing with.

And fyi, "NPS resistant mites" are not found just in CA. Spidermites can adapt and become immune to the chemical if used incorrectly to dispose of them anywhere. I believe this happens when the NPS are left in the rooms for long periods of time with regular ventilation as preventative measures which causes a low enough concentration over a period of time for the mites to simply get used to them.

I wish there was a way we could test this, as it's the only way this little debate can be solved. This isn't a fogging/gassing in days of old, it's a faint fume slowly released by a resin. I'll admit I don't know if it does accumulate in any amount on the plant, but my money is on it not mattering, and that combustion releases more carcinogens to be released than any residue. Also, maybe the faint water vapor from the plants' respiration breaks it down, IDK. It's just that you say not to use it during flower. I did that and it was the only time I ever used NPS, they kicked ass, so did the weed, and I'm still healthy. Keep in mind that it was toned down, I'm assuming partially in response to being sued.. And I'd rather leave my plants unwashed than destroy trichomes and risk mold. Just my opinion/hypthesis. Don't take it too seriously.

You don't get it. This isn't how cancer works. You don't just inhale a product once or eat something once and Bam you've got cancer.

It is the slow accumulation over time that reaches a critical level, then you're doomed.

Think about how many cancer patients go to the doctor and the doctor asks, well lets see if we can narrow down your source for this cancer.
Tell me your history.
The patient is like, well one time I spray painted my house, and oh yeah I accidentailly dipped my hand in a jar or such and such and I eat at McDonalds every third day and yeah I had a grow where I used NPS and I have to sit in traffic an hour a day, etc, etc, etc.

Why do you think cancer is such an epidemic today, because we are surrounded by toxic chems, everywhere we go.

No need to add that one last straw that broke the cancer camels back by using NPS.

Not to mention the neurotoxic effects that have nothing to do with cancer.

I'm going to sticky this for a while.
Someone once told me they are "phytotoxic"....
IE: somewhat toxic to plants. Is there any information to back this up ?

"And I'd rather leave my plants unwashed than destroy trichomes and risk mold."

Thats why I say they should not be used in flowering... Even if you did rinse them, there could still be residue inside the buds from the NPS being in the room throughout the flowering cycle because you obviously cant wash inside of them.

Im not trying to make this a debate thread.

Thats not what this is about, Its already been proven to be a carcinogen...

The point of this thread is to give caution to people about what they are using on their plants and in their homes where not only they live but family and pets aswell.

Also, to inform people on the safer way to use them so that NPS doesnt start showing up in everygrow as a "cure-all" remedy and have growers all over the world breathing in carcinogens...

Just think, If years from now, marijuana growers start getting cancer, they will blame it on marijuana itself and not on the pesticides and chemicals that are being used to produce our fine herb.

Thanks for the info Mr. Hades. I've used NPS once several years ago...had some plants in the beginning stages of flowering that were infested. Luckily I haven't had to use them since. One-time exposure is one thing...I'd hate to find out the hard way what the cumulative effects would be.

I will be much more careful if I ever need to use them again...and certainly not in/on/near flowering.

Well I have been using them continuously for 3 years. No spidermites, no fungus gnats, no nothin'. I even use smaller one in my photorons, no problems. Just wash your hands after handling and do not stick your nose in them and you will have an infestation free grow.

The debate isn't whether it's carcinogenic, it's whether the specific NPS product leaves any kind of residue that settles on the plant. I've read all the links posted in this thread(the most recent one is 12 years old), and none of them suggest anything about that.

I've used these before and worked great but that was once and prefer not to use em. How do you know that they are mostly depleted in a week or two? Is that from manufacturers info/testing or are you just guessing?
