Gnats, I had quite an infestation a while ago. Wife found a remedy for me that worked AWESOME. take an old jar place some sliced fruit in the bottom and just cover the fruit with balsamic salad dressing. Cover with siran wrap and hold in place with rubber band. Poke holes in wrap with tooth pick and leave in your grow area. With in two weeks I had no more gnats! That was 4 months ago and they're still gone!
Great grow area, looks clean and pretty! Keep up with the great work, and every time I see LEDs in use I'm amazed how well the girls do under them!
