Now, let’s get down to it by understanding and accepting a couple of key points and rules of thumb. 1. Start To begin, herbaceous root systems require near 100% humidity , ideally, at all times, otherwise the root tips die back. The root tip is the very small end of the root that is divided into three zones. The length is variable and depends on many considerations such as plant variety, temperature, past water levels and much more. The root tip is responsible for absorbing t ...

What is pH? pH (short for potential Hydrogen) is the measurement of acidity and its opposite, alkalinity in a solution. Neutral pH is 7.0 pH. Acidity measures below seven pH (7.0pH) with alkalinity measuring above it (7.0pH). Why is it important to measure pH? It is important to maintain a hydroponic nutrient solution at a pH level where the elements in the nutrient solution are consistently available to the plant. If the solution is too acidic or too alkaline it can cause ...

What is conductivity? Conductivity (measured in ppm, EC, TDS, CF) is the total soluble salts contained within a liquid solution. Pure water does not contain salts, so it has a conductivity measurement of zero. By adding soluble elements to the water, electricity is able to move through the solution giving it a conductivity rating. So why is it important? Using hydroponics as an example, different crops grow well at different levels of nutrient strength (Electrical Conductivity - EC ...

Although there are ideal EC values for each plant type, this does not mean that a range of plants, all technically requiring different strength nutrients, cannot be grown in a home situation together. The grower simply lists the range of EC values and picks an average value. For most home systems this value is between 1.2EC and 2.0EC depending upon the requirements of the predominant crop types being grown. The pH values given here are broad, note that the average is 6.0 - 6.5pH for hydroponic applications. Below is a list of crops with the ideal EC and pH values th ...
