ok, im 4 days into 12/12 and everything is starting to decline. i waited for my timers to kick on this morning to take a look at my girls. one of them looks completely limp and falling all over the place. the other one looks really good, but is starting to get white powder on the leaves (mold). this wasnt a big deal for me at first. then i look into the buckets and they are swarming with little black bugs that look like gnats! ill upload pictures when i get home from work

It sounds like 2 problems. The fungus gnat adults that are flying around are less of a problem than the fungus gnat larva that are eating your roots. You will need to water with something that will kill them. See your hydro dealer.

The white powder is probably powdery mildew, a fungus that you will need to fix, too. Spray your plants with a light coating of water containing Neem oil, Baking Soda, and liquid dish soap. Or you can use any Pesticidal soap like Safer's, and add Baking Soda (1 tsp/quart).

Good luck,

ok so i scrubbed out my resovoir, changed my hydroton rocks, and flushed my roots with a shitload of lukewarm water and then 3 gallons of flora shield diluted solution. and for the mildew i set my growroom into a negative pressure zone (more exhaust, less intake). everything seems to be going fine. ill check again in the morning

Umm, all good things to do, but I don't know if FloraShield will help with the gnats. It's used to control pathogens in the res. (plus, it's damn expensive!)

And no pressure thingy will kill spores of powdery mildew.

I've noticed a few gnat like creatures flying around my crop, don't seem to be doing any damage. I'm going to have to look into this further. I think though that they are just common gnats, the type you swallow while walking through a park. But what is a common gnat and what do they eat? That's what I mean, need to look into it further.

I hope that your crop is fine Sublime. All I thought we needed to worry about were spidermites, now it's gnats too. Mold Gnats?

I think my gnats are there because about a 3rd of our crop is in a manure & soil mix. I've checked them all over today and there's not a single insect on the leaves. I think they're harmless. It's just that I remember Sublime saying the same thing about his gnats some time ago. It's kinda got me worried.

yeah before they werent doing anything. and the adult gnats dont cause problems. its the eggs they lay that do the damage. the babies eat roots. one of my plants was dying and pretty much fell over. so i pulled 10 clones from it and chopped it down

I have never had a problem with gnats.. I just hang the sticky thingy's and increase air flow.. they don't like windy conditions..

My gnats sit on top of the soil, but they are all over the place in this country at the moment. I've spotted them outside the grow area too, also outside in general. Loads of dragon flys too, approaching a building the other day and it was like a scene from a horror film, literally thousands of dragon flies all over the entranceway.

Dragon flies, I've heard, have the most toxic venom in the insect world, we're just lucky that they can't pierce human skin.

So the gnats lay the eggs in the soil. I've gotta get some stuff.

Thanks for the advice though Sublime, but I've got 20, Those little %&*#$ are going to spread all over the place. If they haven't already. That damned manure, because our air flow is sweet, any windier and the plants would fall down.

I think outdoor growing should stay outdoor. I've gotta get into hydro, if only because it makes more sense.

Are all gnats bad?

Apple cider vinegar works great too. You just need to change the acidity so the mildew can’t grow.
