BigSmo did! He thought they came in his drain, but I've heard of several people that got them from Roots Organic. He had a BAD problem with them.
Got a question for you guys..
Any of you guys having issues with fungus gnats in Roots Organic?? I have everything potted, gave everything it's 2nd watering, 1st with Mega Crop, and when I went to check on things this morning, it's like I gathered every gnat within miles.. The only thing that is consistent is it's Roots Organic.. It's the ONLY base soil I use.. My areas RH stays between 45-50% because of my dehumidifier, I wait until the pots are wicked light before I dry.. The only thing I can think of is I got a bad couple bags of Roots Organic, and now I have to take some serious countermeasures.. So when the hydro store opens in a couple hours, I'm gonna be there waiting for them to unlock the door..
I had this issue before I used this stuff called Microbe Lift BMC when I did hydro, and it worked well, took a couple days but I could literally notice a difference.. Well, that was almost 4yrs ago, and although I've stored the stuff inside, I kinda feel like it doesn't work anymore since I added it at the first watering when I had first seen a couple flying around.. Now, if I tap nearly any of the pots, it looks like cockroaches scattering when the lights come on.. I think it's already starting to affect a couple of my smaller seedlings..
Just when you think you've got your shit together... Murphy is quite the asshole!!!!!

Neem oil is not that difficult to find as long as you don't go looking for it as a pesticide . It can't be sold that way in Canada . But if you have an Indian store the sells women's makeup ingredients you may find neem oil .
