Kindbudzanswered grow question 6 years ago I highly advise to use neem oil and spray on the foliage. Make sure to spray the top and underside of the leaf.you may also try insecticidal soaps. The key is to reputedly spray the foliage as it is instructed on the packaging. Typically you will have to do it for a week or so every day to make sure that you have killed everything. You could if you would like as well but large mosquito netting and drape it over the plants. Place ladybugs inside and they should devour the spider mites. Every grow I use lady bugs I typically have no issues. Good luck on your grow!
