Our Comprehensive Buying Guide


Hydroponic gardens are increasingly popular, especially because it’s such a controlled way of growing plants that if you do everything right, there’s a very high chance you’ll get the desired crops. This also means that nutrient-making companies are competing with each other to make better products and reduce costs, which is always a good idea.

On the other hand, there is a lot of information available on this topic and there are so many brands already present on the market, then you might feel a bit overwhelmed when it comes to making a choice. For this reason, this guide is here to shed some light on the matter.

Liquid or Solid Hydroponic Fertilizer

This is one of the first things you want to ask yourself, given that there are certain differences you should be aware of. Most plant nutrients are available in powdered form, so what you will have to do is combine the substances in the right ratios to get the right formulation and, thus, optimal results.

The liquid alternative is actually a powdered formulation in which the manufacturer adds the necessary quantity of water and other substances. This means that you can simply add it to the water and nutrient reservoir and start feeding it to the plants, as soon as it’s diluted in the right ratio.

Liquid fertilizers might be the preferred option for two reasons. The first one is less need to handle the product, as it’s already in this form and all you need to do is add water. Secondly, there’s a lower chance to accumulate nutrient residues in the water, given that the mix is already partially made by the manufacturer.

On the other hand, powdered fertilizers come with lower shipping costs, as they weigh significantly less. The same goes for any associated storage costs, so they are usually more affordable than their liquid counterparts. They are also a better alternative for large-scale farmers, as storage needs are greater for these operations.


Natural vs. Synthetic Formulas

We all know that the agricultural industry comes with significant technological advancements, so it doesn’t come as a surprise that today, synthetic nutrients are being made that are just as effective as the natural alternatives.

When we say “natural” we mean that the active components are made of natural sources, some examples being compost manure or animal waste. Synthetic, on the other hand, means that the active elements are chemically prepared in a lab.

Natural nutrients come with excellent safety indicators and they work well in improving yields, but the only potential matter here is that it’s difficult to establish the exact proportion of every single active nutrient, so maintaining consistency might be a problem.

Synthetic nutrients, on the other hand, do deliver this consistency, so there are no highs and lows in terms of production, but are chemical-based, which means that they might interfere with some particular plants and thus affect some crops.

Also along the same lines with consistency, some of you might wonder whether it’s a good idea to change the nutrient solution. The answer here is “No” because, besides the medium growth that nutrients provide, the solution also needs to develop beneficial bacteria and microorganisms.

These are crucial for keeping fungi and algae at bay and, thus, the crops healthy, so changing the solution can be a catastrophic action. You can add water only when it’s truly necessary and avoid draining more than 25% of the original nutrient solution.



Frequently Asked Questions


Q: What nutrients should I use for hydroponics?

The answer, in this case, depends on the crops you are planning to grow in the system. The most popular elements found in these nutrients include Nitrogen, Phosphorus, Potassium, Calcium, Sulphur, Magnesium, and Iron. On the other hand, these are just a few of the essential ones.

If you want to obtain the right results, you should, first of all, make sure that you accurately know what the plants you are going to grow need in terms of nutrients. Then, once you have this information, you can look for specific products that are already formulated in the right and balanced mix of nutrients for your crops to thrive.

Of course, you also need to make sure that you use them correctly and according to what the manufacturer recommends, but once you get the hang of everything it’s not a very complicated process.

Q: Are hydroponic nutrients safe?

Hydroponic plant growing is widely used, given that it’s a solution that ensures reliable results and, usually, bigger yields. If the nutrients used for this process are sourced from natural elements and they are properly used, they can provide a safe solution for the increasing demands of our population.

Studies are still being conducted in order to determine if plants that are grown this way are, in fact, as nutritious as those grown in soil. On the other hand, given that the process is still rather new, it takes time to gather the necessary data for long-term studies.

In the end, what matters is what the plants are fed, so if the nutrients you plan on using are made by a reputable brand and come with all the necessary details on safety and dosage, you shouldn’t worry about this matter, as it’s probably not the case. However, it’s true that you can run little tests yourself, by growing the same plants in the two conditions.


Q: Can you grow hydroponics without nutrients?

Hydroponic systems cannot work without nutrients, as this is the only source of food that plants have in order to grow. If they don’t have access to the nutrient solution, even for a short while, their growth can be affected and they can even die.

Given that hydroponics is all about yielding large results in a controlled plant-growing process, it’s easy to understand why the nutrients are key to any such operation. Therefore, if you currently have such a system, you shouldn’t think about experimenting with withdrawing the nutrients if you want your crops to live.

Just like the soil, the substances create a layer of nutrients and beneficial bacteria that both feed and protect the plants. This layer is vital and it also works to make the plant stronger from one year to the next, depending on the type of crops you are growing.
