Hey Big KF ! so sorry bro, in english these are called fungus gnats. they are a pest, and they lay eggs in the soil. there are a few remedies, some are chemical some are organic, but of course not very much works except biological warfare. So it's gonna be a three step process. first get some Steinernema feltiae which are nematodes which are microscopic worms that destroy eggs and contaminate the flies and make them sterile. simply buy some of that and follow the instructions on the packet for "outbreak" not "prevention". Second, get sticky strip, a lot of sticky strips... spend like 20 bucks on them, and put them up all over, including over the soil, at different heights here and there, and ... everywhere sticky strips... finally, get some sand and make a top layer on your soil to prevent re contamination. as final things, increase the air circulation, and never wear outside clothes in the grow room or near the grow room. Hope this helps ! 🚀

SoG first time, 6x Quick One AutofloweringThis SoG setup could work? I've choose 5L Air-Pots and I can place 6 of them inside the 60x60x140 tent, still not sure about applying defoliation but I'm guessing that will be necessary. First time SoG, I've always grown pairs of photoperiodic plants in the same tent.Week 1

After inspection using a microscope i found a very tiny thrip, so tiny it is invisible to the naked eye. I am a week or 2 from harvest, the only insecticides that i have are black soap and neem oil so no treatment. What can I do? Is there any risks(bud rot for example)?Week 9
