Okso I have run into an issue with some aphids. Found larvea on the top portion of the roots above the water line. Did a little internet research and I had none ofthe products recommended so I did an experiment of my own. First I sprayed the little bastards with neem oil and let that sit for 1 minute, then I filled abucket with hot water, approx 110 degrees and let the roots sit in it for a few minutes, rinsed with cold water and it appeared they were dead, or at least no longer moving. I then cleaned my dwc bucket and mixed a new batch of nutes. Sprayed my tent and plants with neem and put 1 Hot Shot No Pest Strip in the tent and one outside in the room.Hopefully I havent killed the plant. We shall see over the next day or so. Only saw them on the White Widow.
