Bake it, or even easier go get a bag of pool filter sand and put a 1 inch thick layer on the top and water it in. Gnats should be gone within the week after that.

You know the root of the fungus gnat problem is overwatering right??

^ I hate it when people come to that half-baked conclusion. That simply isn't true and others have mentioned this around here. If you over water and you have fungus gnats, then certainly it could exacerbate the problem, but you can't tell me it is the 'root' of the problem. The real root of the problem is that these little flies lay hundreds of eggs in your soil; the larvae feast on organic matter in your soil and possibly the fine root hairs, they pupate and emerge as adults ready to lay more eggs. Thus a few gnats from the outdoors can turn into tens or hundreds fairly quickly.
I've dealt with gnats and we've tried the "let your soil dry out until the plants wilt" method- as gnats continued to hover above the soil line.
Case in point: I once had a small amount of soil sitting in an uncovered container, left over from transplanting. Never had I applied any water to it at all, just bone dry soil sitting out in open air for about a week. One day I go over to examine and take care of it, low and behold theres tens of little fungus gnats hovering about doing their thing- laying eggs in this bone dry soil.

You guys got it twisted gnats are only a problem for young plants and Moist soil will attract them(that's why I choose rock wool)and if you're so worried about them use neem oil with your feedings(start off with weak doses)

Blue Dream, Grand Daddy and Purple Kush under 1000 watt light hoping too yield big

What do you use for your grow?
Do you think I'll get a pound off 1 plant?

Let us assume that gnat larvae really don't eat root hairs at all and eat exclusively organic matter in the soil; I still don't fucking want hundreds of them flying around the grow room, getting stuck in the buds, or flying around the house plants, or flying around me or my pets.
Neem drenching would kill the beneficial fungus and detritivores that I want in my living soil. I use bacillus thuringiensis (israelensis) which keeps their numbers down substantially. Cedar oil (GoGnats) is also an option. And diatomaceous earth, of course.

Go got some Mosquito Dunks, which is the Bti, sold at most home improvement stores. Crush up a dunk as best you can, put the powder in a gallon jug with some water, shake it up and let it sit for several hours or over night and then water all of your plants with it. Do this every other week, and within a couple weeks you should notice less of them.
It is good to do use the dunks along with sticky traps and a dusting of DE where ever you see the adult gnats like to congregate. They also find their way up drainage holes at the bottom of the pots and lay their eggs there also, so I work DE into the carpet around the pots. Those that land in it and are exposed to the DE will die eventually.

No doubt, I did see them by the drain holes those fucks, any amount of money I'd pay to get rid of these fucks for good...

AGREED. Also, liquid BTi is available for pretty cheap, and can be added directly to puddles, trays and reservoirs. The dunks work great too.

Gnats thrive in rockwool from what I've read guess your fortunate.
