You will know the war is over when they are all gone.

Are they ever really all gone? I may not be that critical about them I guess. If a few are floating around it is no big deal. If things are damp a lot the numbers rapidly multiply and get out of hand. At that point it is a problem with me.

I use 50/50 perlite/peat and they are no problem the first planting. I re-use the soil twice and it is the second go-round that the gnats get bad.

If'n your pots go dry every 2-3 days the gnats wont get too thick...at least here at 8000 ft. altitude. I try to use the smallest pot so I can feed a lot, the soil gets dryer faster, I use less soil, and things are easier to move around. Indicas seem to like to go dry between feedings rather than moist all the time and this helps with the flies. Also, an acid growing medium promotes fungus, moss, and mold and that is what the little devils are eating. Bigger pots stay wetter, and are colder in the winter too, and this can cause slow growth and Ph/Nutrient problems.

To me, fungus gnats are like washing my truck...why bother because it is just going to get dirty again anyway. Unless they are slowing the ventilation fan down I just let em buzz.

That's all well and good,but if you leave ANY of the adults alive,they will lay eggs and the larvae will eat your roots,which could end badly with a dead plant or dead plants.

Hmm... Well, I guess that I have been extremely lucky. I always have a few flies by the second planting in the same soil, but they rarely get bad enough to treat by harvest. No dying plants, and roots all kinds so things are working.

Fungus, and gnats, would probably thrive in organic soil more? What kind of soil do they grow in best?

How about a plastic covering over your soil? Maybe just a sheet of that yellow cellophane with a slot for the stem. Might get by with no poison at all?

well am going to try everything in the books to see what works best.

That's a good idea,roswell.
