Growing plants hydroponically can be challenging especially if we haven’t taken the correct measures to ensure nutrient aeration and/or water stability. Air stones provide oxygen to the root zone, this is what helps roots rapidly form, without the excess oxygen inputted into the nutrient reservoir the plant can suffer. Always ensure your nutrient reservoir is sufficiently aerated to get the best possible results from your plants, if nutrient solutions sit for more than 3 days unaerated they will most certainly go off.
