To be honest. I've tried everything
Cannacure.. lots of other pest. But once they start laying eggs and you got a high RH environment. So it just takes 1 fruit fly, spider mite to lay up to 50-200eggs.
So, I've found getting fruit fly traps and anything long and sticky. You can cut up place up and down nodes.
Hang the fruit fly traps near your lights as they tend to fly up to the light and extractor fan pulls them up close to that when they wee.
Anything crawling. You need to lace your plants nodes and all areas around the pots. Set traps so they have to walk on to the trap. So push soil up around the edges so they gotta talk awalk over them.
There's a ton of stuff you can do
But seriously letting your top soil dry out. You can do a few simple water feeds from the bottom. And then scoup up any dry soil, as it'll have larva in it. And once it gets wet again the larva trigger again if only freshly laid.
So, fruit fly traps. You'll get packs of 40 you'll see them on my diary Gnats and dealing with them I go into depth. But, in general the stickies will catch most of them.
Good luck.
