Do you see any little black flies in the top of the unit. I had the same problem but they were in my cocopod, not the root area. If it’s fungus gnats they turn into those little black flies. I would add a cap full of 3% peroxide in the water. And for the top maybe sprinle some diatomaceous earth on the top of the cocopod but make sure its not soaked. The top of the cocopod should be as dry as possible. They live in the coco and go to the top when ready to hatch. The diatomaceous earth basically rips they outer skin whennthey try to pass it. I also recommend to not lift up and expose your roots or keep checking them for many reasons. They dont like light. If you notice a lot, you might want to rinse off the roots quickly in water gently and try to leave the lights low to not stress out the plant too much. I hope this helps somewhat.
Thank you guys, you all been very helpful, just added a cap full of 3% peroxide hopefully I don’t see anymore, and I did see about 2 of those flys killed them they turn into ash… hopefully all is well
Those flies will lay more eggs. Be careful
Yes I did they are in the coco pod and when moistened for 2-3 weeks they hatch out they are called “fungus gnats” I had them when I opened my door one day 5-10 flew out and that is all I have had.
They pose no threat to your plant, they can eat the roots though but if a couple gets in your res, the bubbles from the air pump will eventually pop up and knock them down into the res and that point they will die in the res and either get sucked out at drain and fill or turn into food for your plant. 
Hey guys so I just got a tent, and trying to grow organically, you guys mind if I post tent related stuff here?
Most definitely I would love to see your technique and what your working with!

Soon going to transplant to 1 gallon… some of the bottom leaves are turning yellow any idea why? I figure I underwater them because I was to worried about over watering
