how to prevent mites/fungus gnats

how do i prevent em???!

are they already in the soil u buy from home depot/lowes or do they get in there some how

combat them with some sm-90 in ur res available at local hydro shop
can also be used as foliar spray and it smells great very citrus'y

Comes in the soil/ you bring it into the grow room. THere are a million ways. Do what mauh12 said, or for a real sure fire way get a sulfure burner However that doesnt fix soil problems.

any other solutions!? so that means all the soil has that stuff already in it =/

Shot glass full of vinegar works for me.


Just keep it topped off once or twice a day they land in the vinegar and die.

Takes about a week.


My advice stop buying that mass produced shit.

somebody here told me to put play sand on top of the soil . it traps them , they cant get in or out. i did it and i now have no more gnats. hope that helps

#1Get some hot shots pest strips and put one in your grow room.#2get some neem oil and spray down your grow area. always make sure to clean you grow area thorouly(important). good luck

thanks for the help guys =))
