How much nutrients to use in a hydroponics system?

There is no question that hydroponics is a good alternative to growing plants in an outdoor soil based garden. However, it takes more than basic knowledge to growing hydroponically. Items such as the appropriate amount and feeding of hydroponics nutrients should also be taken into consideration. If you are new to hydroponics, you may have be consumed with researching whether or not you are feeding the proper amount of nutrients to your deep water culture hydroponic system.


The point here is to keep the balance of nutrients as it is very important in the promotion of proper development and growth as your plants enter the various growth phases. The first thing you can do is either purchase a quick start nutrient kit and identify the type of nutrients that your plants are already receiving. Oxygen and carbon are among the essential hydroponics nutrients needed for vegetation; however, they are generally supplied naturally through water and air, and absorbed through the plant’s roots. Therefore, you no longer have to include them in your list of nutrients that you will be feeding to your plants since in a deep water culture hydroponic system, your oxygen is supplied by an air pump and you are growing the plants in a large water supply.  This leaves the nutrients needed to feed your plants during the growth phases.  Many company’s make liquid nutrients and plant food, however we recommend a liquid nutrient made for growing plants hydroponically (here is one we tried and like).


Familiarize Yourself with Hydroponics Nutrients


The basic hydroponics nutrients that should be included in your list include potassium sulphate, calcium nitrate, monopotassium phosphate, potassium nitrate, as well as magnesium sulphate. Sulfur and nitrogen are very important in the overall supply of proteins and amino acids. Phosphorus is very important in the overall growth and photosynthesis of plants. Magnesium and potassium serve as catalysts in the production of sugars and starch. Nitrogen and magnesium play a very important role in chlorophyll production. And of course, calcium contributes to the strength of the cell walls of the plants, boosting its overall growth.  Or, simply purchase a starter kit and enjoy watching your plants grow — fast!


The amount of hydroponics nutrients that you will be feeding your water culture highly depends on the type of plant that you will be planting in a hydroponic system. While you can mix the nutrients on your own, the safest way to go is by purchasing pre-mixed nutrient solutions that are available in local garden shops or in our hydroponic nutrients for sale online.

The good thing about these nutrient solutions is that the amount of hydroponics nutrients are already pre-calculated in order to suit the needs of the plants that you are trying to grow. With expert advice from a local gardener, you do not have to worry about being a newbie in this field and there are many guides that you can read or simply purchase some liquid nutrients and read the label – it can be that easy.

Why grow plants hydroponically?

The 21st century has seen rapid urbanisation and the global population is now expected to grow to more than 8.3 billion by 2050. Currently, 800m hectares – 38% of the earth’s land surface – is farmed and we’ll soon need to give over another 100m hectares if we continue to use current agricultural methods. That’s not additional fertile land that actually exists though, so some are investigating the potential of vertical farming.

It has been suggested that a 30 storey 27,800,000 m2 vertical farm could be achieved within one New York City block. That farm could feed 50,000 people, providing 2,000 calories for every person each day. With results like that as a prospect, it’s easy to see why enthusiasts see vertical farms as the future.

Growing up

Vertical farms are still very much at the conceptual stage. The idea is to cultivate crops on multiple levels within high-rise buildings in urban areas. It’s not an entirely new proposition, with architect Ken Yeang suggesting a vision of high-rise plant cultivation in mixed-use skyscrapers as early as the 1980s. Professor Dickson Despommier, the leading international advocate of vertical farms, describes them as “a global solution” to the world’s urban food needs.

Vertical farms do indeed have many advantages. They would enable us to produce crops all year round using 70% less water. We wouldn’t need to use agro-chemicals and could avoid the adverse environmental factors that affect yield and quality in more traditional farming. And if food were grown in urban areas in the first place, we could eliminate the financial and environmental costs of importing food into towns and cities. Read more here.

One University’s Commitment to Hydroponics

Believe it or not, The Commons, Kennesaw State University’s state-of-the-art dining hall, feeds more than 5,000 guests each weekday! The facility opened in August 2009 and coincided with the introduction of the campus meal plan program. The staff of Culinary & Hospitality Services took advantage of an incredibly unique opportunity to incorporate industry-leading sustainable practices in a new building from the ground up.


Did You Know?

The Commons has more than 10 hydroponic units. Hydroponics refers to the process of growing plants in sand, gravel, or liquid, with added nutrients and without soil. Rainwater run-off from our buliding is used as a water source.

The process consists of three steps: germination, propagation, and cultivation.

The Commons will produce 600 heads of lettuce every three weeks, which will result in about 9,600 heads of lettuce per year for use in the dining hall.
