So I found a couple of fungus gnats. Or at least that's what I think they are. I killed them. Do you think 2 of them would do any damage? Should I get something to treat the soil just in case? Turned up my fan a lil to dry out the top layer of soil quicker. Hoping that will keep anymore from trying to come around.

Ok I'll make a trip to the closest gardening store. Do you think I should make this urgent? Like I said it was only 2 and I check my plants everyday so I know they weren't in there too long.

Never just 2 dry out top of soil and turn the fan up a bit and spread some sand on top that should do it! Yellow stickie cards put in pots will tell you how many you have thay love yellow and can't resist them. LolLast edited by Potted; 12-09-2016, 03:32 PM.

Yellow sticky traps for the adults. BT (bacillus thuringiensis) for the larvae. BT is found in Mosquito dunks/bits. I've used the dunks in hydro, I crumbled them up and fed it into the media. Worked great. For soil/coco you can do the same, just crumble them up and add it to your water. I wouldn't add nutrients with that watering to be safe though.
Kingfish's recommendations should work well too. I haven't tried spinosad on gnats and I've never used DE so I can't speak to how well they work.

Alright here's the pictures. Hey could you guys tell me what that little white spot is? I've had one other one before this. I've only caught them when I have found a moth in there. Royal Nugs no I haven't. I wouldn't quit know how to confirm. I just figured it was them because they were on top of the soil. And I get what you mean. But I stirred around the top layer of soil and I couldn't see any larva or anything.2 Photos

The bad news is that I have never heard of only 2 fungus gnats. The good news is that they are reasonably easy to get rid of, and they don't really do harm to the plant unless you get them bad and they damage your roots.
I had quite a few so I put about an inch of sand on top of my peat based medium and let the top of my medium dry out more between watering's. It took about 10-12 days at least to get rid of them all.
If you use sand or DE on top of your soil, it is best to water in a way that doesn't wash it all down into your medium.
completed 7 grows
what I have learned so far:
environment maters more than nutrients
at least a dab of nutrients in every watering
effective flushing before harvest is critical to quality
