Look no further. There are new products on the market now for spider mites which are inherently organic, and many are still going through testing. It appears they all kill the eggs as well as mites but don't hurt the plant. I went to the hydro store and this guy tried to sell me the stuff at $60 a spray bottle, and told me it was the best for mites.
I told him I would probably need about 5 spray bottles to get all of the leaves on my 6' plants, which he agreed. He added that I should do it every 14 days...
5 bottles every 14 days for 2 months of flowering, thats $1200!!!!
I think the guy thought I was stupid or something, because right on the front of the bottle there was a list of ingredients.
An fancy chemical emulsifier, and Rosemary oil.
So I asked him, "Hey could'nt i just buy some Rosemary oil and mix it with a soap and use that for 1/20th the price?"
He looked shocked... then picked up the bottle and read it. He said "Yea, I think this this is just Rosemary oil and an emulsifier...."
When I got home, I did some research on Rosemary oil. Theres data out and here is just 1 of the links along with a link for Rosemary Oil at GNC for just $7.
I wish someone would have posted this info awhile ago. Gee it sure would have saved me some time.
