The pepper spray is not difficult to cook up and is very effective. Actually the most effective I have experienced.
I do not use chemicals for any part of my grows.
I will however fog a room with pyrithin (sp) after an infestaion [plants removed] or before starting a new grow. Spider mites...
Yes I can vouch for this method. I had a bad infestation some months ago.
Researched and found the Caliwash recipe. Followed it carefully and in 2 weeks my plants were all returning to good health. Vigorous growth followed by a nice harvest were my results.
Good luck with your Spider mites are...
