I started a hydroponic. I’m getting white crystals forming on some of the clay pellets at the top. Does anyone know what it might be?
Salts left behind after evaporation?
Probably as mentioned above. What hydroponic method are you using?
Air bubbler that drips water to the top. I rinsed the pellets with my well water. Next time ill rinse them with distilled water
Ya that’s probably just build up from your water or nute solution.
