On a couple other forums, I read that the SNS 217 is nothing more than pure rosemary oil(rosemary essential oil) and can be had at a fraction of the cost at GNC or most health stores. Look into that to save yourself some coin.

I had some mites on a clone and started doing some horticultural research and came across essential oil of Rosemary as an effective organic mite treatment.
Here's an excerpt from my grow blog:
Now, I'm pretty dedicated to natural and organic methods (for myself and our plant), so my first thought was to look more into
Neem oil (which I had laying around the house). While I was searching online, though, I came across this post describing how to use rosemary oil to get rid of spider-mites. I was intrigued (mostly because I think
Neem oil stinks!), and did a little further research. First, I found this page on spider-mite control from the University of California - Agriculture department, which recommends rosemary oil for controlling spider-mites on organic strawberries. Then I found this 2005 University of British Columbia graduate thesis on using rosemary oil to control spider-mites - on page 30, the author states "Rosemary oil is relatively effective against insect and mite pests. The aromatic vapor of rosemary has ovicidal and larvicidal effects on several stored product pests and the two-spotted spider mite.". Apparently, the smell can repel thrips, too. The lethal concentration for mites was found to be 13.19 ml/litre. The author, Miresmalli, concludes "that rosemary oil can be considered an acaricide/ibsecticide against the two-spotted spider mite," which, given all the data he provides in the 107-page document, is good enough for us. There's some indication that eucalyptus or peppermint oil could be up to 30% more effective, and if the buggers come back, we'll explore those routes.

To make the rosemary anti-mite spray, I mixed 10ml rosemary essential oil into 710 ml distilled water with 2 drops organic dishsoap to help the oil emulsify with the water. A note: the lethal concentration according to the study would be 9.3649 ml oil/710 ml water - I erred on the side of killing the hell out of these pests.
