Floramite breaks down to harmless by-products in about 28 days......it can be sprayed on some vegetables so it can be sprayed on buds up until around the 4-5th week of flowering. I've tried almost everything I could get my hands on- Liquid Ladybug, MIghty Wash, Azamax, Calicleaner (hot pepper spray), alcohol wipes, pyrethium bombs, etc. and nothing got rid of them for good. They would always come back after a week or so, no matter how much I kept spraying, rotating sprays, etc. At least now I know that Floramite WILL take care of the problem for at least a month.........it takes up to 3 days to kill but will stay on the plant and disrupt the mites to get you to the end.
I found out Azamax and some of the other things mentioned will burn the plants if applied (pick one of more of these): 1) with the lights on, 2) if the room is too warm, 3) applied too heavily, 4) applied over other products w/o washing them off 1st, or 5) some strains are more sensitive to some sprays. Nothing can be done with the burnt leaves- if they are bad, pick them off.
