The importance of root maintenance to a healthy root system cannot be overstated. All successful growth begins with a well-developed and flourishing root mass. Roots play a crucial role in a plant’s physiology performing key functions such as absorption of water, minerals and other soluble and gaseous compounds. Roots also act to stabilize and anchor the plants and assist in keeping them upright while bearing any weight of fruits and flowers; this is especially important when growing high yielding, fruiting and flowering crops. Regardless of the growing method, it’s impo ...

Quality differences in COCO substrate In 1998 the popularity of coco rose enormously causing a shortage of its raw material. As the leading potting mix and substrate producers could no longer ignore the product, they started to use raw material from new sources without considering the quality aspects. This resulted in huge crop damages, especially in France and the Netherlands. In order to prevent delivery problems in times of high needs CANNA went overseas and made substantial investments in local infrastructure. Concrete bunkers were buil ...

Calcium occurs throughout the entire plant. It is used for many processes in the plant, however, calcium is most important for the growth process. It has a regulating effect in the cells and contributes to the stability of the plant. Plants have two transportation systems at their disposal: the xylem vessels and the sieve vessels. Most nutrients can be transported via both systems, however, for calcium this is not possible. Since calcium can be transported almost exclusively via the xylem vessels, it is an element that d ...

Phosphorus plays an important role for all living organisms and is an essential nutrient element for plants and animals. It has a key position in the combustion processes of the cell, and in the total energy transfer of the plant. It is also a 'building block' of the cell walls, the DNA, and all sorts of proteins and enzymes. For young plants, the presence of phosphate is indispensable; about 3/4 of the phosphorus consumed during a plant’s life cycle is absorbed in the first quarter of its life. The largest concentrations of phosphorus are found in the developing parts o ...

Magnesium is an indispensable element for a.o. plants. In plants, it represents a building block for chlorophyll (leaf green), and therefore, it is essential for photosynthesis. At the same time, magnesium plays an important role in the energy transfer. Together with calcium, it is also a component of tap water, influencing water hardness. Inorganic magnesium fertilisers are produced using the same bases that are used to produce potassium fertilisers. About magnesium in short ...

Iron is a vital element for plant life. Iron has a number of important functions in the overall metabolism of the plant and is essential for the synthesis of chlorophyll. In general, iron is poorly absorbed by the plant. It can only be sufficiently taken up by the roots in certain forms and under proper conditions. Soil seldom contains too little iron, but it is possible that forms of iron that can be absorbed by the plant are lacking. The absorbency of iron is strongly dependent on the pH. Ordinarily, there is sufficient iron present in absorbable form in acidic soils. ...

Nitrogen is one of the important elements a plant needs. It is an important part of proteins, chlorophyll, vitamins, hormones and DNA. Because it is a component of enzymes, nitrogen is involved in all enzyme reactions and plays an active role in the plant’s metabolism. Nitrogen is mainly absorbed by the plant in the form of nitrate and ammonium. It can also be absorbed via small organic molecules. It is important that the balance between nitrate and ammonium is correct in the feeding otherwise the pH in the rhizosphere (environment immediately sur ...

Sulphur is one of the molecular building blocks for a number of proteins, hormones and vitamins, such as vitamin B1. It appears in many important plant tissues, such as in seeds and in cellular moisture. In the form of sulphate, sulphur fulfils an important role in the water equilibrium in the plant, as well as in the soil. For hydroponic gardening, all the nutrients a plant needs are given while watering. As a result of this, fertilisers designed for hydro culture contain high concentrations of lime and sulphur. In order to prevent calcium and sulphur from reac ...

It’s well-known that plants use macro and micro nutrients for tissue development and good biological progress. However on occasions we forget that carbon is also one of the necessary elements for the life of plants, and all organisms – of course. Not only are essential elements made up of carbon but so are desired metabolites like those in sensory properties such as aroma and flavour. A lack of carbon would not only result in a lower biomass but the plants would also be of inferior quality and strength. This precious element is absorbed through the plants’ stomata in gas form, ...

Let’s face it, this is the mantra of too many growers. There are so many self identified ‘boosters’ out there it would take a super computer to count them.

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 ...

Measuring the temperature of a solution Control your nutrient solution temperature and prevent big swings. Temperature affects plant growth, flowering, seed production and pollination. If it’s too cold, seeds won’t germinate, cuttings won’t root, flowers won’t produce pollen. Your plants will grow slowly or stop growing altogether. Too hot, your seeds won’t germinate and cuttings won’t root. Plants can die from oxygen deficiency, or succumb to pathogens that like higher temperatures. Most plants prefer a root zone temperature of 18 ...

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 ...

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 & yields. Many other deficiency symptoms can occur when too much of one mineral is "out competing" others. Most hydroponic nutrients are formulated based on "pure water" and this ...
