Wettable sulfur once a week until flower, then switch to predator mites.

I got my first signs about a week ago and started spraying diluted ethanol and citric acid every third day. Still to early to do say if its doing the trick, but I've killed mites with this mix before. Afterwards I use diatomaceous earth to keep any survivors at bay until resin formation starts, then i rinse off the DE because resin pretests the plant pretty nicely.
Have you used sulphur to combat russet mites successfully before?

I haven't had much luck with DE stemming russets at all... I'd rather let the local predators come in and eat.
Sulfur, when applied once a week, will knock out just about everything tiny or fungal.
There remains some question how much it affects the soil microbes, but I haven't noticed any real problems.

Thanks, one thing I noticed on my autos is that the ones that started showing resin really early seem to have protected themselves from mites very effectively, but the ones that were in veg or just starting to flower when warm weather started up got eaten pretty badly before I started spraying lemon ethanol on them and now they're recovering pretty nicely. So I think cannabis resin make it hard for the mites to eat and with that in mind I started spraying cannabis tincture with the lemon instead of just plain ethanol.

Not quite. Russets actually EAT the trichomes.

Worthless faggots keep ruining all my plants with their greedy root-devouring worm babies. I'm tempted to switch to hydroponics, I get the idea that it'd be EASIER than plain dirt growing.

Hawthorn flies lay eggs in fruit.
Fungus gnats?

Dilophus febrilis, their larvae eat at the roots.

I noticed gnats only thrive in fresh peat
once composted they never show up again

Thanks for the tip, at this point I'm really just tempted to go hydroponic for various other reasons as well though.

Those aren't hawthorn flies, but regional naming conventions and all...
Have you tried throwing down a layer of sand over the surface?

You can get yellow glue sheets, the flies are attracted to yellow get stuck and die
Or anything yellow coated with cooking oil
This wont help a peaked infestation but something for a new grow.

At this point the internet can go suck a dick with everyone giving those little flying faggots a different name.

The sand's a good suggestion, actually. I was just thinking of something a little bigger that allows more water to seep through like those little volcanic rocks or perlite.
I'll check if my local gardening store has these, it'd be nice to have in my house regardless of growing.

Either way, I invested in a small but complete hydroponics set just to test it out. If it's not to my liking I can always use the perlite I got as a growing substrate to cover up a pot of soil. But at least I can put 'experience with hydroponics' on my separate cannabis-themed resumé.

Covering the soil wont help
The fly will seek out the bottom hole(s) and lay eggs there instead
