Yea I don't trust the FDA, EPA, any government agency for that matter. They are all bought and paid for.
With that said, from the information I have found across the web and from people I know who have supposedly done lab tests, the half life is roughly 30 days, which means 99.9% of the chemical is out in 60 days. I absolutely despise using chemicals and have never before used them in my grow. It took me about a week to decide to use it, but when all other options are failing, I would rather try and save the crop and do some lab tests myself.
When this crop is finished, I plan on sending some samples to the lab. If people are interested in the results, I will share them here.
Also, as I mentioned previously, it is important to note there is a huge difference between indoor and outdoor. The above numbers are a reference to outdoor.
Unfortunately right now there is a lot of misinformation and lack of studies regarding the science behind cannabis diseases due to federal regulations. I just got done spraying the remaining spores with green cure, if that proves to be a temporary band aid I will unfortunately be forced to spray with a higher dose of eagle 20.
