You sir are wrong. The sand COMPLETELY eliminates them. I speak from 100% firsthand experience. My growroom no longer has gnats with only sand added to the top layer of soil.No way man. That will slow them down but that won't eliminate the problem. You gotta kill em and keep em from having babies too. Neem Oil is the best, hands down. I promise you that if you use it, your problem will be gone and if you use it like every 4 weeks or so, they'll never come back. Not to mention that the plants love all the trace nutes in the oil. You just gotta try it.
