The higher the amount of salts, the higher the EC level or the electrical conductivity. But that's what this article is here for! Let's take a look at one of the simplest and most popular methods of hydroponic gardening today - Deep Water Culture, or DWC. If the pH of the nutrient solution is too high or too low, then the plant will not be able to take in the minerals in the water. I believe, depending on brand and line of nutrients, plants, lighting, and temperature/aeration of the water, ph can fluctuate from 5. As a result, it is generally accepted that during the vegetative growth stage, EC levels should be kept within 1. We understand when you buy the wrong product, or change your mind and redesign your garden before you open your new product. What should the EC be for hydroponics? As mentioned above, EC will vary from stage to stage, but during vegging, EC should be 1. Be careful not to confuse them. The nutrient that I have used, I have tried with EC = 1. Semi-Hydroponics™ (AKA “Semi-Hydro™” or just “S/H”) is a unique and simple orchid culture technique we developed as a way of keeping our plants alive while we traveled extensively on business (it’s hard to care for plants when you’re not there – and I averaged 13 flights a week for 3½ years!). A HYDROPONICS COURSE THAT WILL TAKE YOU TO THE NEXT LEVEL! For people who already understand a lot about hydroponics This course has been developed by industry professionals with decades of experience advising hydroponic businesses and farms. pH/Nutrient Testing Dialing in your solution's pH and nutrient levels to accurate ranges is key to promoting nutrient uptake, leading to healthy, happy plants. Extensive, yet simple instructions are included. Nominal EC and pH Values for Hydroponic Crops. You will have to spend several hundred dollars at the very least to obtain something fit for purpose.
