Fungus Gnats I Think

Discussion in 'Cannabis Infirmary' started by Bbang420, Jul 11, 2018.

  1. I was told I have an issue with fungus gnats bc I brought a sticky card to the grow shop with 2 of the culprits on it. I just tried to find the larvae from them and found nothing in 2 of my clones that were put into cups. The dirt had no evidence of anything n nothing on the roots. I did recently after they dried out hit them with Azatrol so maybe it killed them off (2 doses in 2 weeks). I do know I only have this issue in my veg room not in flowering my guess is bc the soil dries out in the flower room bc it's hotter n I have a 600 sodium over there.

  2. You we’re told? Show pics of yo nats.
    If they truly are fungus nats in your veg you definitely have them in yo flowers.

  5. The guys at my local grow shop told me that they were fungus gnats I just didn't see any larvae. I've dealt with broad mites outside before n back in 07 with spider mites my first ever indoor setup.

  6. It was a pain in the ass to get closer pics with my phone these things are small. Only reason I say they aren't in my plants that are flowering is bc I see no visible damage n those plants the soil dries out too quick also I have a b/w barrier

  7. Yes, you are correct. Gear up, how many plants?

  8. Probably like 10 or 15 but I knew that's what they were n have hit them with Azatrol already twice. My thing is I didn't see any larvae when I emptied out 2 of the clone cups n some are starting to come back. I'm buying gnat nix this Friday

  12. Yes I have a loop to look. I did see one moving dot the other day but I was looking for something bigger from the pics I seen but really I have only seen one I guess n it was tiny as hell

  13. I was more worried about them being root aphids was looking for a slug type of thing when it comes to the gnats. I guess the little dot was it.

  14. My flowering plants I have them staggered so I get weed every 2 weeks. This will probably put that on a little hold until maybe Friday with moving in the next rotation

  17. Gnats usually show up from overwatering causing high humidity around the plants.

    The yellowing in the garden pic may also be an indication.

    The larvae die off with a good wet/dry cycle.

  18. That's what I figured so I let them dry out to the point of almost wilt n then I hit them with Azatrol. It's what I had on hand until payday that can be used as a drench. But yeah the over watering thing is what did it. I have a fan on them now plus there's an ac in the window that probably adds to the humidity compared to the other side.

    It's a work in progress took over my roommates grow op. It was a total mess dirt everywhere vacuumed up the dirt he even had some top soil up there from before I moved here that I told him not to use but he left it sitting up there.

    So I bought a new hood, some 4' t5s n some b/w. I want to frame out a wall up there n staple b/w to it with zipper, setup a component board make it look professional but I'm trying to ease it in there. It's fun but I hate when shit fucks up your rotation

  19. Thanks everyone I feel a lot better that im 100% sure it's fungus gnats. From what I read much easier to take care of them than root aphids. It also makes sense considering the soil is pro-mix bx with mycorrihaze ( probably spelled wrong) it's a type of active fungus it always worked well for me plus it comes in bales.

  20. Good-Day Bbang420:
    I Totally Agree. Not Root Aphids-If You Ever Get Them You'll For Sure Know It.
    2 Growers Here In Oregon I Know Got Those Nasty Root Eat'in Monsters And Both Were
    Hydro Set Ups. You Could See Them Just Eating The Roots. This One Grower Threw Everything At Them.
    {Which I Don't Agree With} Then After He Killed The Aphids He Got Mites Super Bad/After The Mites This Grower Actually Harvested That Crap And Used It...
    The Other Grower Gave Up-Too Overwhelmed.

    Yeah... Really Great Info You All Came Up With-> No Worries, Because If You Ever Get Them
    They'll Usually Fly Right Up Into A MH Or HPS Lamp/Also, At Times, Some Potting Soils Aren't Sterilized
    Thoroughly {Sorry To Say-Like Black Gold And Such} Good Show Everyone-I Really Enjoyed This Thread.
    Peace Be With Us All And Onward With Your Great Skills Bbang420 ! Thanks Very Much, Brother Will
