Unformatted text preview: Index: GrowFAQ : What levels should I maintain for my hydroponic nutrient, temperature, pH and TDS/EC? Added by: MisterIto Last edited by: 10k Viewed: 226 times Rated by 21 users: 9.00/10 I follow and highly recommend the following parameters for hydroponic nutrient solutions for aeroponic, ?bubblers?, drip ebb and flow, NFT, passive, rockwool and wick systems. PH 5.1-5.9 (5.2 optimal) TDS 500-1000ppm, EC .75-1.5 Temperature 68-78f, 20-25c (75f, 24c optimal) The pH of the nutrient solution is a major determinant of nutrient uptake by the plant. If the pH wanders outside the optimum range of between pH 5.1 and pH 5.9, then nutritional deficiency and/or toxicity problems can occur. Fo hydroponic nutrient solutions used with inert media, keep the pH at 5.2 for optimal elemental uptake. It is at this point tha roots most readily assimilate nutrients. These pH and TDS/EC recommendations may seem low relative to the normally suggested range, but are based upon information garnered from "Hydroponic Nutrients" by M. Edward Muckle andsuggested range, but are based upon information garnered from "Hydroponic Nutrients" by M....
