So I switched over to organic growing last year and whilst I think the smoke is probably better, and it's an easier grow method in general for me, I've had issues with gnats in every grow.
I'm about to start my next grow and wonder if there are any preventative tips that you can recommend, apart from not overwatering, I've tried neem cake last time and they still showed up.

I just applied my first round of 2 drops per gallon BMC Microbe Lift. That comes highly recommended from the folks using it. Gnatrol is the other highly recommended option I see here.

We don't have Gnatrol in the UK, I think its Lava Lite is the equivalent over here.

Mosquito bits, mosquito dunks, any form of BTI, Diatomaceous Earth, slice up a potato, place on top of soil and replace every 2 or 3 days.

Micronized sulfur is what i use when in veg.
If they pop up in flower i use sticky traps and mosquito bits in my water for any larvae

I should add sticky traps for the fliers if you go the potato route lol.
The larvae will eat into the potato and then by replacing every couple days you eliminate the larvae as well as the fliers with stickys

Are you growing a cover crop at all? If not, you can consider putting a 1-2 inch layer of perlite on top of the soil to physically block the gnats from gaining access to it to lay eggs. Sticky traps will also help. If necessary, you could move the perlite aside to topdress, and then re-cover it, the same way that people who mulch their plants do.

Hey, no cover at the mo. I have Perlite here and didn't think I could use it because I thought it would get in the way of top dressing but I'll try it.

1.5 inches of sand on top of your medium with DE underneath the sand. They will be gone simple and easy.
