Best DWC Nutrients: Top 4 Products You Should Use!

We know that ground plant obtains their nutrients from the soil. Have you ever wondered how hydroponic plants obtain their nutrients? Unlike ground plants, they get their nutrients from a solution of water and minerals. It is no secret that nutrients play an important role in healthy growth and flowering. Therefore, if you are growing your plant in a DWC medium, you will need to find the right kind of nutrients to feed them.

There are many best DWC nutrients in the market, but you don’t get enough information regarding what they are best for. This is why this article may be the most important thing you will read today!

In this article, we have listed the best nutrients for DWC hydroponics in detail so that you can easily select the best one for your plants.

But what really is DWC (Deep Water Culture) and what are the fertilizers you can use in it?

What is Deep Water Culture (DWC)?

Deep Water Culture systems are distinct in that they are designed to immerse roots in a reservoir of continuously flowing nutrient solution. It is a hydroponic system in which plants are grown without soil, Yep, No Kidding!

So how do the plants get nutrients if there is no soil involved? This is a surprising detail.

In DWC, roots are submerged in the water present in the reservoir the whole time. To provide nutrients, a nutrient solution is supplied which is readily accepted by plants. A nutrient solution is made by mixing fertilizer products in water and then supplied with the help of a pump.

How to Use the Best DWC Nutrients to make the Best Nutrient Solution?

As there are so many companies producing DWC plant nutrients, determining the best one has become more difficult. The general hydroponics plant nutrient series is frequently the first option for beginners. Others prefer to prepare their own hydroponic nutrient solution.

In any case, there is a checklist of things down below you should consider if you want to make the best DWC nutrient solution:

Know Your Plant’s Nutrient Requirements

For proper nutrition, all plants require phosphorus, calcium, nitrogen, and other essential elements. While most plants require the same micro and macronutrients, the ratios in the solution can vary greatly. This is primarily determined by the type of plant you are growing.

Also, if you are unsure, you can always consult a DWC nutrients guide online. The key is to comprehend them so that you can provide the best organic hydroponic nutrients to your plants.

Check The pH Level Of The Nutrient Solution

The pH level should not be underestimated because it has the potential to kill your hydroponic plants. Plants typically require a pH range of 5.5 to 7, with 5.8 to 6.3 being the most ideal. Micronutrient toxicity may occur if the pH of the nutrient solution falls below 5.5. A pH level greater than 7 becomes too alkaline for plants.

Lower pH may be easier to deal with because you can simply add pH up by General Hydroponics. If the pH is above the desired range, then adding pH down by General Hydroponics is a good way to deal with this situation.

Check the Oxygen Level of Your Nutrient Solution

To properly oxygenate your DCW plants, you should determine the oxygen level of your nutrient solution. The oxygen level, like the pH level, should be optimal.

Toxins accumulate when the oxygen level is too low resulting in permeability of the roots to water and minerals. If the oxygen level is too high, there will be excessive oxygenation, which will still result in poor nutrient and mineral absorption.

Check Your Electrical Conductivity (EC) Reading

Electrical conductivity may appear complex, but it is simply the ratio of the nutrient solution to the amount of water. The objective is to keep the EC level between 0.8 and 3, with the normative value set between 1.5 and 2.5. Using electronic EC meters is the simplest way to verify this. Manual computations are a little more difficult, but they are also an option.

The result of a low EC is not that concerning because you can simply adjust upwards. A high EC is a cause for concern because it increases the risk of nutrient burn which is a condition in which plants dry out or die as a result of an overabundance of fertilizer.

Wrapping Up

All-inclusive, the only source of nutrients for DWC hydroponic plants is a nutrient solution. The best DWC nutrients we have described play an important role in the healthy growth and flowering of hydroponics plants.

Aside from the required nutrient concentration, there are a few other things to consider when preparing the solution. This includes raw water quality, pH level, EC measurement, oxygen level, and, most importantly, nutrient requirements of your grown hydroponic plants. If everything will be in the proper range, only then you will end up with a top-quality yield.


What is the best nutrient solution for hydroponics?

General Hydroponics Flora Series is the best nutrients for DWC hydroponics. It is relatively simple to use and contains all of the nutrients that plants require. There is no denying that DWC nutrient strength depends upon the composition of nutrients.

Primary nutrients are necessary for strong and healthy roots, whereas secondary and micronutrients are necessary for accelerating plant growth in later stages. Lucky for you, both primary and secondary nutrients are present in the Flora series.

How often add nutrients to DWC?

You should follow the DWC nutrients schedule recommended by experts. It is recommended to replace the nutrient at least once a week. In other types of DWC, you can keep it for up to 3 weeks, but it’s best to check the solution regularly. When the pH is too low/too high, or the nutrient solutions completely change color, then replace the old nutrient solution with a new one.
