Best DWC Nutrients: Top Nutrients 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 such as nitrogen, phosphorus, and potassium. These nutrients play important role in their 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 on the market, but you don’t get enough information regarding what they are best for.

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.

What is Deep Water Culture?

Deep Water Culture systems are distinct in that they are designed to immerse plant roots in a reservoir of continuously flowing nutrient solution. It is a hydroponic system in which plants are grown without soil, Yep! So how do the plants get nutrients if there is no soil involved? This is a surprising detail. Roots are submerged in the water present in the reservoir 24/7 in this system. To provide nutrients, a nutrient solution is supplied which is readily accepted by plants.

Deep Water Culture was given its name for two reasons. Firstly, you usually grow with a reservoir that can hold a reasonable amount of water. More water in your nutrient solution means more stability! The second reason is how much of the root mass you immerse in water.

Qualities of best DWC nutrients (DWC nutrients guide)

Here are some features of the best hydroponic nutrients:

  • These nutrients are designed specifically for hydroponics.
  • There is no organic matter as nutrients are provided via minerals
  • The minerals are “chelated” which means they are easier for plants to absorb at a greater range of pH levels.
  • Contains a lot of micronutrients (to make up for what might have been found in the soil)
  • NPK ratios that work best

Best Nutes for DWC have these qualities in them.

Top 4 best DWC Nutrients

DWC hydroponics nutrients can be obtained from a variety of market products. The majority of growers use a three-part nutrient solution: grow, micro, and bloom.

How to choose the best DWC nutrients? (Buyer Guide)

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 who prefer to be more hands-on prepare their own hydroponic nutrients. In any case, there is a checklist of things down below you should consider if you want to get the best DWC nutrients:

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. Furthermore, if you are unsure, you can always consult a DWC nutrient 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 acidic for plants. Lower pH may be easier to deal with because you can simply add up, but if that is the case, you will need to use some pH-down solution. Hence, to reduce the level of acidity, add a mixture of the pH down solution to your nutrient solution.

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 optimized. Also, some low-cost options include manually monitoring the appropriate temperature and running an air pump. 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 you still have any queries, then check out the FAQs portion.

General Hydroponics Flora Series is the best investment for your deep water culture system. It is relatively simple to use and contains all of the nutrients that plants require. Primary nutrients are necessary for strong and healthy roots, whereas secondary and micronutrients are necessary for accelerating plant growth in later stages.

How often add nutrients to DWC?

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. You can follow the DWC nutrients schedule recommended by experts. It’s time to replace it when the pH is too low/too high, or the nutrient solutions completely change color.
