1.release lady bugs and praing mantis as soon as you strt flowering and leave them in there the entire time. they will do the job, neem oil is next and you should not get them, fingers crissed, the whole thing with mites is that you have to avoid them radther than kill them, killing an mite infestation is very painfull and ends up returning so clean your crowing area with 5ml bleach in 1l of water and spray the outside of your house with hardcorde chemical insect killers and inside as well but before you put yor plants in there. Once the plants are in i like to spray arround the grow tents and the outside structure of the tents no spot is missed, regular check up on the plants is a must there is not one time i walk into the room and check my plants leaves for mites, i have been attacked twice in my old crib and mainly due to the age of the house and that it was all woood!!!!!!! avoid wood at all times. they like to hide in the addict of the house or in the basement and attack your shit when its nice and moist.
another thin i o is i run my humidity arround 30% when the climate outside gets warmer i have realized that mites love humidity that is 50% or higher. keeping the temps under 30 degrees celcius helps a bit as well, you can slow the spread of mites by dropping down the temp.
My friend was fucking arround 1 time and had a clone with mites starting to attack so what he did was put the clone in the frigerator and wolla they all died but so did his plant. So if you have mites and you harvested then simply put your fresh cut buds in the freeyer or refrigrator and let them die off this way, im sure smoking mites is no fun. even though im sure i have smoked some and didnt notice anything.
mites are the wors and must be preented i go through my entire house once per week and look for spider webs as soon as i see fresh webs i spray the entire house and look for the fuckers responsible they all must die.
now i have hear dof some spiders killing otherspiders and insects which is nice bu t i don take that chance, insect and bacteria free environment is ideal.
