Managing the pH level in your hydroponic system is one of the most critical aspects of successful growing. When your nutrient solution's pH drifts too far from the ...

Hydroponic growing is gaining serious traction in Australia, and for good reason. Whether yo ...

EC stands for Electrical Conductivity and PPM stands for Parts Per Million. Both terms are used to determine the nutrient levels of water within your hydroponic system. Whether you're new to hydroponics or have been growing hydroponically for years, it's important to keep up with your nu ...

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 s ...

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. ...

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 ...

Hard water results primarily from excess calcium, magnesium, sodium and other minerals dissolved in the ground water. Too much of any of these can greatly alter the mineral nutrient balance in the root zone and nutrient reservoirs. Sodium, for instance, competes with Potassium and you may end up with Potassium deficiency symptoms like brown leaf tips and less than optimal growth ...
