how to neem oil flush soil for fugus gnats

add an inch or two of sand on top of the soil. thats all you gotta do.......

1 tbl spoon/gallon. add till soil is drenched

thanks for the info. mountain farmer are you sure thats the right dosage. i would not like to injure my girls. maybe that mixture and sand.

also how do you sterilize the sand? i know fo get white sand to reflect light. dont want to bring anymore bugs into my grow room. any help is greatly appreciated.

mountainfarmer the directions say 2 tablespoons per gallon but that if for spray bottle not a soil drench.

man I just went through a gnat problem for a while!! Finally got ride of them, used a product called "go gnats" which i'm not sure if it worked to well.. But then used "azmaz???" Not sure about that name, ill check when I get home for sure and let you know. So shortly after this product they are almost all gone. I used sand, stripes and neem oil and still couldn't get ride of them.. Another thing I did which could have been the biggest help was change soil, was using a local nursery brand and I think it was is the soil when I bought it.. So I would try changing soil and ill hit you back with the name of the stuff I used.. I had the problem BAD for months and months, this finally helped... Sand does help a lot just a pain in the ass, makes pots very heavy

carter, i think its called azamax. i have been looking into it. about the sand how do i know i'm not bringing any more bugs in the grow room. Hot shots no pest strips work well too.

You can put your sand on sheets and bake it in the oven at 350-450 f for a short time to sterilize it.
