The Best Hydroponic Nutrients: A New Life to Your Garden

Hydroponic systems are getting popular in the last few years due to more efficient growing that doesn’t take as much effort as when using soil. One of the major reasons why people convert to hydroponic plant growing is because you can change the nutrients and amount of those nutrients in the water. This allows you to entirely control the plants and remove the deficiency, but this can happen as long as you use the proper nutrient supplements.

A Guide To Hydroponic Nutrients

We have already established that the use of nutrients for hydroponic systems is not only beneficial but essential as well. Using these nutrients can be either complex or as simple as setting up your hydroponic system. If you’re a beginner who isn’t sure which models are good for you, then either check our reviews list or stick with a reputable formula that works with most people. Before you head on and start experimenting, just stick with one kind and follow their instructions in detail.

An issue with most nutrients is that some of them are quite expensive, we saw that some models tend to cost about $0.30 per gallon of nutrient solution. But you don’t need to spend all your money on the most expensive models, you can buy models that are as efficient as the premium ones. Sometimes these nutrients bottles can cost you just 2 cents per a gallon of nutrient solution, but be sure that it isn’t just barebones and that it is worth your time.

Since nutrients are an essential part of your new hydroponic system, you need to make sure that it is easily absorbable by your plants. Since there is not soil and you have water instead, you will need to make sure that the nutrient solution is soluble in water, because if it isn’t, then your plants can’t take it. Since you’re using water, you as a grower will have absolute control over which nutrients reach your plants and in what concentration they do. This allows you to customize your water according to the needs of your plants.

If you have a nutrient meter by your side, you can also monitor the number of nutrients currently available in your water as well as their consistency and concentration. Since there are more than 20 types of basic nutrients needed for a plant to grow, you will need to ensure that all of them are available for your plants. It’s even better if you can add some extra nutrients that can make your plants grow faster. A good nutrient model will also offer you mineral nutrients which are mostly available in most nutrient solutions.

Some of these models are Nitrogen, Potassium, Phosphorus, Calcium, Magnesium, Sulphur, Iron, and others. It is not essential for you to have all of the mineral elements, but it is a great plus if you do. Since plants grow in stages, the best thing you can do is order models that come with a package of multiple bottles. These bottles are usually very different compared to each other and each one specializes in some stage that boosts your plant’s growth.

Common Myths And Questions About Hydroponic Nutrients


There are a lot of reports about using nutrients in hydroponic systems, most of these myths are false while some of them are correct, but to jump right to the facts, there is nothing wrong or unhealthy about using hydroponic nutrients. The main reason why people are afraid of buying hydroponically grown vegetables is that they might taste different.

This is most commonly said because people tend to talk about the industrially grown vegetables that are grown in hydroponic systems. This is false mostly because you, as a minor grower, will not affect the vegetables in a way that will artificially make them look better or last longer. If you were to grow tomatoes in your garden filled with soil and in a hydroponic system, you would notice no difference in taste. Sometimes it is even better to use hydroponic systems because you can add nutrients that make the taste even better.

Another question that many starters ask is whether it is possible to make your own nutrient solutions. Most of the times, making stuff yourself is a lot better than if you buy it in your local market or order it online. Of course, this is the same case when it comes to nutrient solutions, but be aware that if you’re a beginner you won’t have an easy time making it. Even professionals have trouble because of how complicated it is.

Nitrogen is one of the essential nutrients in your supplements, but it is also one of the hardest things to add in a mix. But in order to use nitrogen, you will need to buy or create a nitrate solution, which is also hard. You can get nitrogen from various sources like grass and urea, but it isn’t simple to extract it. Mixing your mowed grass with water will do nothing.

You can always find a company that makes bottled solutions. Getting any sort of certified organic nutrient is easy and they come with various manuals that explain to you how to mix it with water and in how many doses. In the end, we have to remind you again that this is no easy job, sometimes it is just much simpler to buy a commercial nutrient package.

Note that you should use the proper nutrients during each growth stage. Nitrogen will be used a lot when the plants are in their vegetative phase of growth, in order to grow they will need huge amounts of this nutrient. Later on, when your plants start to mature, you should reduce the amount of nitrogen and they will need nutrients like phosphorus, potassium, calcium, and magnesium in order to properly grow.

Take Care Of The Following Things When Using Nutrient Solutions

Just like in any field, when first starting out a beginner will usually miss out on a lot of do’s and don’ts. In order to make things a lot easier for you, we have gathered up some of the most important cautions that you will need. First, you should always keep the temperature in check. By keeping track of the temperature, you will make sure that your plants can absorb the solution as efficiently as possible. Both the mix and the water should be between 68 and 72 degrees Fahrenheit.

It will get troublesome if your temperatures are too high. You will encounter various issues such as algae, which will rapidly start growing in your system’s reservoir. But if your temperatures are too low, the plants won’t survive for too long and their health will decrease every time they are fed. Another important thing is that you put your lids to use, these lids for your system’s buckets usually come in almost all models.

By placing lids on your hydroponic system’s buckets, you will make sure that no parasites, diseases or even algae will manifest. Keep track of how hard your water is as well, for effective and real results, you should check the water’s hardness in ppm. By controlling your ppm and keeping it in balance, you will control both acidity and alkalinity. Try not to use tap water because it will contain a lot of chlorine. But if you’re forced to use tap water, then leave it at room temperatures for at least 24 hours in order to at least minimize the amount of chlorine. This way you will ensure that your plants grow properly.

The last thing you should do is use hydroponic systems made not out of metal, but out of plastic. If your system is made out of metal, then depending on the kind of it, it may interact with your nutrient solution in a way that it will lower the solution’s effectiveness. If you can’t use plastic, then just make sure that the material used is BPA-free and food-grade safe.
