Things Consider Before Buying the Best Nutrients for DWC
Specifying the DWC nutrients is quite tricky as many companies produce different types of nutrients for particular purposes. Beginners can go for general nutrients for hydroponics and experts can make their own nutrients. However, below are the vital factors to consider while buying the best DWC nutrients.
Required Nutrients for Your Plants
Nitrogen, calcium, and phosphorus are the obligatory nutrients for your DWC plants. Generally, most of the plants need these macro and micro-nutrients to grow ideally. But the ratio of the nutritional elements can be varied in a particular solution. It depends on the plants you cultivate in your hydroponics system. A good DWC nutrient guide can help you to know what plants need what type of nutrients to grow properly.
The pH Level of the Nutrients
The pH level of nutrients is significant and you should consider it with importance. The incorrect pH level can be very harmful to some specific plants. In general, most plants require 5.5 to 7 – this required pH level can be changed slightly. The pH level less than 5.5 can increase the toxicity and above 7 can increase the acidity in the solution.
It is easy to increase the pH level of a lower solution but for a pH higher solution, you will need to use a pH down product. The pH amount can also be varied depending on the various stages of growth. The flowering plants need a lower pH level than vegetative plants.
You can get an electronic pH meter to check out the level of pH in DWC hydroponics system.
Electrical Conductivity (EC)
The EC seems complicated at the first notice, but as a gardening enthusiast, you need to have an idea about the term. It is actually the ratio of the nutrients to the water amount in the DWC system. Electrical Conductivity (EC) should be between 0.8 to 3.
Generally, the standard value is selected between 1.5 to 2.5. The low EC can be increased quite easily, but the higher EC can cause nutrients burn. In this stage, plants may die or straight dry out because of the huge amount of fertilizer. Before choosing the nutrients for DWC, use an electronic EC meter to measure the exact ratio.
The Oxygen Level
To ensure the proper growth of your DWC plants, fixing the right oxygen level is important. Without oxygenating, your indoor plants will not receive a sufficient amount of oxygen to flourish. Like the EC level as well as pH level, optimization of oxygen level should be taken gravely.
Using dissolved oxygen meters is a way to figure out the oxygen level but it can be a good option for experienced gardeners. Some other manual options are available that will not cost you anything. If the oxygen level is high or low, plants can’t absorb needed nutrients as well as minerals. Therefore, depending on the oxygen level, you should choose nutrients for DWC plants.
There are some other tips that you can follow:
Depending on the growing stages such as the vegetative stage and flowering stage, you can choose the purpose-based nutrients.
Liquid fertilizers allow your plants to absorb nutrients efficiently. These are also easy to apply in the DWC system. On the other hand, powdered fertilizers seem difficult to mix and use in the solution.
Organic fertilizers are good for plants but they work slowly. Chemical fertilizers offer a better result in a faster period. However, organic fertilizers are eco-friendly too.
Frequently Asked Questions
What do the numbers on the cover of the nutrients represent?
The number represents the ratio of N-P-K that is nitrogen, phosphorus, and potassium. They are macro-nutrients that are quite essential for the plants. If you see the number 2-1-6 on the cover, it means the fertilizer contains 2 percent of nitrogen, 1 percent of phosphorus, and 6 percent of potassium.
What are the best forms of nutrients for DWC?
There are different forms of nutrients available in the market, but I recommend the liquid nutrients as they are highly soluble in water and instantly becomes available for the plants to absorb.
What much of nutrients should I feed the plants?
The amount to be used depends on the type of plant you are growing, the growth stage of the plant, and also the pH level. Usually, every nutrient product comes with instructions and guidelines about the recommended nutrition strength that needs to be applied for the plants at a certain stage. You can feed your plants with nutrients by following the given feeding schedule at the back of each nutrient product.
How often should I change the water solution in DWC?
The water solution should be changed out once in two or three weeks. If you have a small-sized DWC system, then you need to change it more often. Also, you can read our article about Details Guide on DWC.
Are there particular types of nutrients for DWC grow?
The above-mentioned nutrients are some of the nutrients for DWC. They work great for producing a large-yield of crops and also boost the growth and development of the plants in all the cycles. You can choose one from them according to your plant’s needs and also your budget.
