I have used it. I have used it a couple times. It works alright, but I don't think it works well. They key is preventative maintenance. Neem works well for that. I use miticides because I don't have time to fuck around with battling spider mites. Use AVID, Floramite or Forbid. I cycle them all. You see, spider mites are hardcore. The problem should never be taken lightly. I just got rid of them again. Got my new clones from my buddies garden. There were eggs all over them. The plants have been vegging 3 weeks and have 0 signs of mites. If I see eggs or mites again(they come out when your lights kick off), I have a corn cob green led bulb that helps them jump out, I'll spray with Mighty Wash over anything. It is food grade safe, too. I buy 5 gallons at a time, helps with powder too! Thats just me man. Everyone has a different concoction.
