How far into flowering is your buddy? You can use
Azamax, azatrol, or sns 17 as long as you are not past week 3.
Neem oil (the ingredient in the
azamax/azatrol) is a tertiary carcinagen when smoked so not a day past week 3. As far as the bombs the organic bombs (Dr.doom) are toxic for about 3 days and the industrial pyrethium bombs (white small bottle with orange and blue writing) are toxic for about 5-6 days. You can bomb up to the last week if needed but honestly none of the above mentioned products will eliminate all mites. Also enviromental controlls help (higher humidity and lower temp). If he is in veg then buy
floramite,
avid, or
forbid (Pick 2) and spray one on all leaves, and the tops of the pots. Wait 3 days and use the other in the same manner. This will eliminate 100% of mites. things to keep in mind:
1) All pesticides should be applied when lights first go off, if using bombs make sure to evacuate all air before lights on because that stuff is phytotoxic.
2) you could drop a nuclear bomb in the room and the mites will survive if your room is not clean because the little fuckers will stash eggs in bits of soil or foliage on the floor ect.
3) If you have more than 40% of the growth damaged kill the plants. Trust me its too late if you are there
4) azatrol/
azamax, neem, sns17, organicide, or other horticultural oils will control/prevent but if you alreaddy have an infestation you are shooting a bb gun at a frieght train.
5) iF you are mite free in your grow DO NOT VISIT HIS GROW!!! You can easily bring the little bastards back to your girls.
6) DO not use
floramite,
avid or
forbid if you are in flowering alreaddy. they have a toxic life of 30 days outdoors so you wanna double the toxic life if you are growing indoors to be safe because the toxcicity will not degrade as fast inside.
Goodluck and happy trails!
