@KennyRogers, Iâm sorry that your hydroponic didnât work out for you. Iâm just confused as to why you would grow outdoors with hydroponics. The whole reason for hydroponics is controlled environment. You keep it out, youâre exposing every thing and Iâm not even sure what you used on your net pot. It looks like peat moss or coco coir but I wouldnât do that. Also neem oil helps before the aphids travel down to your roots. You got infested because they like moist environment and they had direct access to your stems. Your net pot looks moist as hell. That attracts bugs on top of dead plant matter from the bottom of the plants will attract it. It wouldâve helped if you had a greenhouse or cover. Also hydroguard doesnât help with physical infestation. It only helps with fungus symbiotic growth. If you do it again, next time, grow indoors and use grow stones like hydroton or actual grow stones
