Root Aphids?

[GrapeGod]

I have 12 plants that were thrown into budding about two weeks ago, and now we have black gnat looking bugs flying and some other round yellow-greenish color bugs in the eb-n-flow tray. I mixed some of Ed Rosenthals Zero Tolerance pesticide into a gallon of water and watered them with the pump off for an hour or so. Now waiting for results. Any recommendations??

I had the same problem a few harvest's ago. I solved the problem by using azatrol and by smothering them. The aphids are feeding on your roots and when they are done they will travel upwards towards your flowers. If you "smother" them they will have no place to go and die. You can buy pot covers, they are white and have sizes to fit all pots. It will contain them down to the soil,and also the covers help reflect light on your lower flowers.

These plants are no longer alive. :\ Had to clean everything out and start up with new clones.

Ouch...that hurts. I know ur situation all too well though. 2 grows ago, I had 6 plants in my garden that just shriveled up and died. I wasn't running hydro; I was using soil. I had a 70/20/10 ratio. 70%soil, 20%fertilizer, 10%perlite. Right as my plants started producing buds; i'd say a good 2 weeks after inducing flowering, I had gnats everywhere. And once they start, it's damn hard to completely get rid of gnats. For me, it was anyways. This was my first time dealing with them. I tried everything. Store-bought solutions to spray on the plant which didn't work, home remedies I had heard by word of mouth and the list goes on. I still don't know the very best way to rid gnats in the garden. But 3 things I did in combination seemed to help the most and get rid of 75% of the infestation.

1. sat a couple bowls filled with beer near my plants that the gnats dive-bombed into and perished
2. hung a few sticky fly traps off of my flourescent bulb setup that caught a shit-load of them
3. dug up the top half of soil around the base of the plant to where the roots were exposed and filled up that now empty space, with sand

I know this doesn't help anyone with a hydro setup, but I wanted to share my experience with gnats in my past soil setup. I also learned that some store-bought soils also contain larvae of gnats. If not larvae, some of them contain what the gnats need to thrive and were packaged with the soil unknowingly by the supplier.
