These are so easy to prevent from ever being an issue in anyone's garden with no chems.. Plants that are already infested will take a bit longer to die off. Once they cant lay anymore eggs they will die off.. Gnats and thrips need a consistently moist medium to breed. After you water dont leave standing water in your drip pan. Use a stick to fluff the top 2" of medium so it drys out fast. Once the top layer is dry Gnats or thrips will not go into medium to breed in. U must be consistent in doing this. If your medium drys out quick ea day then you do not need to do this. Having a dry top layer is key. Our plants top layer drys out between ea feeding so we no longer need to fluff. Once you find out how much water to use so this happens your set. Its as easy as that.. We have not seen these in years since we started doing this. This works perfectly in soil. If your using coco you might need to fluff as coco needs to be moist all the time.

Try this it works good luck ..

I agree with this and the best info on the yellow sticky cards. I want to add you can continue to water to runoff say for a bottled nutrient grow but like above keep cleaning the room (and plants and pots) of dead leaf matter and spilled soil etc. and drying out the medium well between watering.
 
A word of warning to anyone who is going to try goGnats. I have several recirculating top watered systems. I mixed the solution at lowest recommended rate with RO to dilute it before mixing into my reservoir. Really thick. Ph did not fluctuate in DG nutes. Within two hours my Green Crack and Sour Diesel leaves were curling under and drying out. Northern Lights and White Widow were okay for the first 24 hours then began to wilt. I panicked and cloned the shit out of them. The clones stood right back up as soon as they hit the water. Wow all the root systems were gunked up with what I assume to be the cedar oil. So then I flushed the roots like crazy and rinsing all the chrysaline residue off the entire system. After a week of removing dead leaves and praying to the weed god for mercy, they all appear to be recovering except for one Green Crack that is still pretty hurt after its sever cloning.
To be fair it did not affect lettuce, peppers or beans that were running off the same res. However, it seemed to to greatly reduce the number of gnats. It also made the entire grow room smell great. Amazon promptly returned my purchase price.
