fungus gnats and hydroculture?
I have a pretty bad fungus gnat problem in one of my plants (I must have overwatered badly). I was thinking of switching to hydroculture to get rid of them, some sort of passive system, either pot in a pot or wicking.
However at a local hydroculture/hydroponic shop I was told that this wouldn't solve the problem, that in fact it would be even more difficult to get rid of them, particularly if I used those clay pellets, hydroton I think they're called?
Have you guys found this to be the case? How do you avoid them? I do have a couple of small open aquariums with no filtration. I don't know if they can hide out in there as well (I stuck some Devil's Ivy in one of them - I don't know if it matters if they're emersed or not. It's not rooted in substrate or anything.
