Commercial growers also often use NFT systems to grow various kinds of herbs and baby greens. The advantage of an NFT system is that the plant roots are properly exposed to the oxygen, nutrients, and water the ...


While aeroponic systems are simple in concept, they are the most technical of the hydroponic systems. Even still, it is possible to build an aeroponic system in your home with relative ease. Aeroponic systems are unique because they do not usually need growing medium of any kind; the air acts the growing medium. The advantage to this type of system is that it provides roots with more oxygen than any other hydroponics growing system. Additionally, aeroponic syste ...


Drip System Drip systems are widely used by different growers because they are very effective for growing hydroponically, low maintenance and produce little waste. How It Works The drip system works by constantly dripping nutrient solution onto your growing medium. The nutrient solution is pumped from the reservoir through tubing, which runs along the top of the growing medium, where the solut ...

How It Works In water culture systems, the plant is suspended in pots, baskets, or cups above the reservoir filled with nutrient solution. The roots hang down and are constantly submerged into the nutrient solution. This system uses an air pump to ensure that the roots get the oxygen they need so they don’t suffocate. The best water culture systems provide many air bubbles that make direct contact with the roots. There are actually two different ways to ...

CONSTRUCTION UNIT HOUSING High-quality LED grow lights are made with a metal housing. If the unit is plastic do not purchase it. Aluminium is an excellent heat conductor and helps transfer excess heat that is produced by the LEDs. DRIVER Look for grow lights that contain a "constant-c ...


LUMENS AND PAR LUMENS ARE FOR HUMANS You may have seen LED grow light information listed in Lumens and PAR. Lumens do not matter - at least not to a plant. Lumens are a measure of the amount of visible light emitted from a source. Chlorophyll mostly absorbs light in the blue range, red range, and far ranges of the visible spectrum. Chlorophyll does not absorb green or yellow wavelengths (although evidence suggests that green light helps drive photosynthesis) ...


COVERAGE AREA LIGHT SIZE The grow light that you choose should depend on how many areas you want to cover. A small 100 watt light may cover 4 sq ft, while a large 400 watt light can cover up to 20 sq ft. Some growers recommend purchasing a larger light because it is cheaper (watt for watt) and they can always back the light off from the plants if the light radiation is too intense. However, this will also reduce the PA ...


ACTUAL LED OUTPUT WATTAGE Comparing LED grow light power When comparing LED lights to HID lighting (HPS/MH), use the actual LED output wattage. To get an equal amount of photosynthetic active radiation from LEDs as you would HID lighting, use about 50-75% less wattage than a HID setup. For example, to get 1000 watts of actual LED power you could use 2 LED panels that draw 500 watts of power in place of a 1500-2000 watt HID system. These numbers represent a wide range, and the actual power will differ depending on the brand, diod ...

CANNA COCO is easy to use Because of the high costs of nutrients and the complexity of sophisticated hydroponic systems, more and more growers turn to CANNA COCO for their personal needs. One satisfied customer stated: “Although I’ve already grown a few harvests, I must honestly say that I still haven’t got a clue about growing. With potting mix everything always went wrong. First, too much water, and then too little. But that’s history since I’ve been using CANNA COCO. I’m the perfect example that coco sub­strate is idiot proof.” ...

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 built ...

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 deposes of little mobility within the plant. It is, t ...

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 ...
