Flies in soil are coming from too much waterings,, cannabis like to have dry periods, and wet periods, flies love wet soil but don't like dry soil.. So what u have to do is just let it dry.. Anyway it will not change a lot for nine days so keep the faith, everything's can be fine !

Hey there I've had bug problems constantly so I get the frustration. My first suggestion would be let the soil dry, very dry, but since time is a factor for you, I would suggest to try to remove the topmost layer of soil carefully and get it out and away. Next have a fan pointed directly at the soil surface always. Add the diatomaceous earth as described by others and possibly replace the removed soil. Avoid anymore neem oil as it will leave a smell and possible taste.
Keep up the great work, keep things clean and stay vigilant. When you do harvest get the pots of soil out and away, and aim for low humidity in your drying space and hopefully the bugs will flee. Other than the bugs, the buds do look great.

I agree with what's been said for fungus gnats and their larve try using diatomaceous earth. It works very well and will not effect the end product in any way which looks fantastic by the way:+1:

Let us know how you get on with the mite issue and not to long now until harvest time :sunglasses:

All the best

Dolomite flour on top of the ground and traps are sticky. In 10 days you can harvest.
Good and beautiful girls!:+1:

I would keep going man, they wont do anything at this stage. I would recommend a product called "Microbe-lift BMC" it is Bacillus Thuringiensis sub species Israelensis. This kills the fungus gnat larvae. Take potato slices and lay them on top of your media and a day later pick it up (the larvae should be under the potato, eating it, they love it) and throw it away. You have fungus gnats because your media is constantly wet. Let it dry out some, the fungus gnat larvae only hang out on the top 2 inches of media. Diatomaceous earth does not work when wet fyi.

Yes Fungus gnats, You could wait 9 days no problem at all. I’d be using H202 to flush her over the last few days will be fine and kill anything left in the soil.

Sounds like fungus gnats put a coating of diatomaceous earth over the top of the soil that will kill the larvae and prevent more from hatching. Other than that keep the sticky traps out to catch as many of the flies as possible
