yeah it's important to do everything you possibly can to keep the fungus gnats away. during an infestation (i know you're not there yet) many folks have good results by watering with hydrogen peroxide 3% at 1/3 strength. What i prefer doing is using the biological method which is using beneficials for example beauveria bassiana and metarrhizium - these are micro organisms that attack the eggs and larvae of the gnats before they mature. this is a kind of preventative measure but you can also use it during outbreak. Beyond that, i would use loads of yellow sticky tape a various heights in the grow room and also on top of the pot of soil. and finally, (i do this too) make sure you cover every intake and seam of the grow tent or whatever space you have with micro mesh, the smallest you can find, to make sure contamination cant really get in passively and easily. Hope this helps ! let's fight and win the war on pests ! 🚀
