Fungus Gnat?

Definitely did not see any negatives from the dunks or the gnatrol switch. I am a little worried about possible raising of my ppms. The don't seem to be getting worse, maybe a little better. I still catch several a day in my sticky traps. I was thinking of doing a potato cube on my soil in each pot to get an idea how bad I have it. I guess gnat larva love potatoes cause it's just a giant chunk of root, I guess I'm just afraid that I'll find a billion gross larva.

I've tried everything under the sun (or HPS bulb in my case)

I used to grow in dirt, moved to hempy buckets (100% perlite) in hopes to get rid of them. It didn't, here's what else I've tried

diatomaceous earth
whole bottles of streight h202
mosquito dunks 1 whole package (8 dunks in each) crushed up in 2 gallons of water
mosquito dunks 1 whole package ground up and placed as a top dress over the perlite
I've let the plants dry out almost to death in hopes to dry these bastards out

next up - hot shot pest strips
It's supposedly bad for you but at this point I'll take a very light dose of poison to get rid of these bastards. They have all but killed my 5 plants in flower and there are signs on the new plants in the veg chamber.

Another update on the gnats:

I still have a few of those fuckers around, I got actual Gnatrol, I beleive its the same chemical as the dunks, but less messy, and mixes better. I've started adding it to my rez to hopefully interrupt life cycles. In the 6x4 veg room with my Hot Shot Strip, there are still gnats however. The population doesn't seem to be growing, but it definitely doesn't seem to be shrinking. These pots were soaked to the core on their last watering a week ago with the dunks, we'll see if that Gnatrol works better moving forward. Another side note in regards to the people reccomending cinamon/hot pepper type stuff. I bought from Home Depot an organic flying pest spray that is a mix of spicy stuff like cayenne and cinamon just for the hell of it. I didn't want to add any more chemicals to the room, but still wanted to do more. My plants did not like this stuff. It was in an aerosol can, and I got a little bit on the lower leaves when trying to wet the top soil layer. Within hours those leaves were done for, wilty and dead. Caused some pretty bad discoloring on other leaves as well that got minor contact. I expect my plants to bounce back from this (may lose a couple recently transplanted cloans.) but this was probably a bad idea :p. I have sticky strips up, still catching a few adults a day. I may try a perlite/sand layer on my vegging plants still in one gallon pots, but its too much of a hassle to try and do it to my dozen 15 gallon pots. It seems like my small guys still have the worst of it, it's my understanding gnats like the newer growth. These fuckers are hard to kill, and this time of year everyone seems to be having issues as they move inside for season change maybe. Keeping the strips up and the gnatrol in my res should at least keep the population low enough so not to have my yields effected for now, until a more permanent solution presents it self.

Same thing happened to me dude.. The Dunks did nothing at all hell the Gnats would chill on the dry dunks I layed on the top of pots. Azamax made my Larry OG strain very sad not the other strains just the Larry OG.. I went the nematode route..Gnats are the devil.

I'm telling you guys look into predatory nematodes.. They munch on the larvae and the adults wont land on the top soil anymore because to them its like jumping in a pool of hungry sharks. I had the same bad luck used everything from Azamax, Hot Shot pest strips, gnatrol, dunks etc.

Mosquito dunks will work in hydro or soil. In hydro, place dunk in panty hose and place in rez, no more mess. It takes a while to kill them all, BTI , the active ingredient in dunks and Gnatrol, is organic. If you are using H202 it will kill the BTI but not the larva, therefor having shitty results. The larva have to ingest the BTI and it kills them from the inside out, tears thier guts up. Keep sticky traps to snag adults, and keep using dunks and you will have success. Has worked for me in soil and hydro bongsmilie

Ah nice I like the panty hose Idea. Gonna add that to the attack. Actually was gonna do nematodes too, but the store was out,getting them Friday. Ive had a hot shot in my 6x4 veg for a while now and still a handful of gnats as well as a case of hypochondria about that crap in the air. The instructions on the package say it's for places like summer cottages and garages you aren't visiting for months at a time. I think that's going out tomorrow. Sticky traps, gnatrol, dunks in panty hose in my RO res and
Nematodes will be my new unified front. I hope in addition to tearing up the larva, the tag team of BTI im using can also add some humiliation And disgrace before bringing inglorious death.

Lol. I hear you. When I first had my experience with those little bastards I was in the cloning process. The clones still looked healthy, but after 28 days still no roots, I was like what tha hell. Got pissed and pulled a clone out of the cube, the stem/root area was covered in larva, they were eating the roots as fast as they would grow. Since then I keep a dunk in my rez and replace every 30 days, havent had a problem since, that was about 4 years ago. The adults are harmless, just annoying. The larva are the trouble makers, they dine on organic matter, your roots! If you are going to use soil get good stuff like fox farm, if no choice and have to get stuff from Home Depot etc better sterilize the soil before use because guarantee anything from those big box stores will have critters, they leave it outside so it gets infested. Happy growing!

Another update, I took out the Hotshot strip, and I feel better, but it does seem like the Gnat population might be going up again. My yellow sticky card is getting a few more guys every day. I've been watering with Gnatrol/dunks, and have added dunks to my RO rez. Still after 2 weeks the population hasn't taken over, but the buggers won't go away. Looks like I still might go get the nematodes. This is in my veg, and I have lots of small plants in there. A couple of them seem to be struggling, I thought at first overwatering, but now I'm not sure. When I poke around at the soil, sometimes a gnat turns up and flies out. I got a 50-100x hand microscope I'm gonna examine the soil with. I really hope I dont see much of anything, a magnified closeup of a buncha larva is something of my nightmares. A spider showed up the day after I took out the HotShot, hopefully he'll do some work for me.

**to update my current remedy is: Mosquito dunks in my RO rez in panty hose to keep debris out. A little Gnatrol sprinkle in my water (I have been too lazy to do the actual math. The instructions are like 3-6 ounces/1000 gallons), and Yellow sticky cards on the ground by my 1 gallon pots. I've tried letting the soil get extra dry (to the point of wilty leaves), and it seemed to hurt my plants and not the gnats, so wasn't a big fan of that.

Do the nematodes work in rockwool cubes? or will they just get rinsed through when they are watered? I am having an isuue with the gnats as well. Azamax did nothing after using the whole bottle. I mixed a strong drench and dunked blocks right in it, changed nothing in the hydro but did seem to help a mother I have in ocean forest. I've heard and read bad things about gognats in hydro. I have bunches of the sticky yellow card traps can keep the population fairly low but can't get rid of them. At this point I don't even run a res anymore, I hand water every day as to control dampness in the blocks and keep the humidity at a staggeringly low 22%. I've read lots and lots on gnats and soil but things get sketchy when you talk rockwool only.

I have some dunks on the way already, as I said before there is no res anymore. Was mainly wondering about the nematodes ability to stay in say a 4x4x4 cube. Thanks for the input.

Here's an update of how things are going with my gnats. 4x6x10 veg area. I did 1 gallon of mosquito dunk treated ro water in the top layer of my 15 gallon pots. I dipped my 1 gallon pots in water and soaked them thoroughly because the gnats liked to hang by the drain holes. 4 days with the hot shot the flying population seems to have gone down a little, but I was under the impression these were way more effective. Time will tell if I was able to interrupt the reproductive cycle. The bugs don't seem ton have effected growth, I did repot a couple of my small guys and the root zones seemed healthy. I'm just worried what they might do if I let them get out of hand.

The Hot Shot won't work if you are extracting massive amount of air. Turn your fan off when the lights are OFF for a dew days and the Hot Shot may be more affective.

Ive been running nematodes for a few days now, can't comment on their specific effectiveness as im doing the dunks and gnatrol too, hopefully thats not killing my nematodes. I do have alot of ventilation in my veg room with the hot shot, i figured that would just help spread the effectiveness of the hot shot around, however, I definitely was not seeing a any dead gnats lying around dying from it, just dead guys on my sticky strips, or live guys in my soil/flying around. The population seems to be under control, but definitely not eliminated. I think my plants are strong enough to withstand a little gnat population, I'm mainly concerned about my fresh clones/seedlings.

Another update to my Gnats. Using yellow sticky traps, Mosquito dunks in my RO rez, a couple doses of Gnatrol to some waterings, and 1 dose of Nematodes, I appear to have all but eliminated my gnat problem after 3-4 weeks. My sticky traps do seem to grab a gnat or 2 a day, but I have hardly noticed any flying around or in my soil for a week or so. In regards to cinnamon/spice/organic solutions, the ones I tried sucked balls. Also make sure to keep that crap off your leaves, I killed a bunch by accident using an organic spicy spray. I'm gonna leave sticky traps up, and keep the dunks (in panty hose, thanks for that idea btw to the guy who posted that) i think indefinitely unless by some miracle I never see another gnat.
