ive been battling a small spider mite infest recently and realized that i have another pest.out of nowere i had 100's of little black nats every were in my bud tent.i think they might be fungus nats but not sure.i got a no pest strip and it seems to be killing alot of them i one day so far.any advice or thoughts of what these things are so i can prevent them in the future.

heres some pics of the bud room.3 hindu kush's,1 northernlights x big bud,1 la women,1 super skunk,and oneraspberry cough,thers at diffrent stages of flower,betweena few days and 3 1/2 weeks into flower.these are a pile o dead nats ,sorry about the quality,the nats in the tent started dieing but the nats in the dirt are still alive so i moved no pest strip on pots

I think 1 or 2 inches of sand in the top of your pots may help

what will the sand do?should i wait longer between waterings and let the soil dry more?what cause these nats,i dont want them to come back when i do get rid of them.

what will the sand do?

apparently the silica granules are sharper edged than most insects prefer. i have used this method in a pinch and it did very little to stop them. no matter how gently you water there is always a small amount of soil and perlite that will push to the top as the sand settles and in a few waterings the gnats have new homes on white sand beaches.
pyrethrin is what i now use and gnats are not an issue anymore.

should i wait longer between waterings and let the soil dry more?

i would. not only should it reduce the amount of gnats it would also "temper" your girls and get them healthy and strong, rather than bloated and inefficient.

what cause these nats

i got mine FREE with the purchase of one bag of Miracle Grow Organic Choice Compost.

thats kind of funny cause i got some 3 day old sprouts growing and there are gnats in the cab and i too am using that mg organic compost. i guess that where it comes from. ill be watching this cause i need to kill them also.
