General Hydroponics Bio Essentials is a mixture of micro and sub-micronutrients that give plants the trace elements they need.
Bio Essentials also contains an organic buffer to help maintain the pH levels of the nutrient solution, and will also help limit the effects of calcium in hard water areas.
It can be used as a foliar spray to add strength to your plants, or as an additive for hydroponic systems or soil.
Please note that GH Bio Essentials is not to be used alongside FloraMicro.
