What Are Hydroponic Nutrients for Vegetables and Why Do You Need Them?

Vegetable plants usually receive nutrients through the soil that they are planted in. 

Hydroponic growing (also known as deep water culture) uses water instead of soil. 

Since hydroponic vegetable plants are grown entirely in water, they are not receiving these nutrients. Instead, you need to add hydroponic nutrients for vegetables into the water that they are growing so that they can absorb the nutrients from the water instead.

Here are some of the best nutrients for deep water culture that are important for hydroponic vegetable plants:

• Nitrogen
• Phosphorous
• Potassium
• Calcium
• Magnesium 
• Sulfur
• Iron
• Manganese
• Copper

Your hydroponic vegetable plants need these nutrients so that they can grow healthy and big as well as ensure that you have bountiful vegetable harvests.

Each type of plant has a different nutrient requirement and you will need to adjust the types of nutrients that you use to meet the needs of your plants. 

Leafy vegetables like lettuce and spinach generally prefer lower nutrient concentrations compared to fruiting vegetables like tomatoes and cucumbers.

You should check the nutrient levels and pH levels of the water that your plants are growing in every 5-10 days. You can check these levels with a multi-reading handheld meter.

The Different Types of Hydroponic Nutrients for Vegetables

Different vegetables have different nutrient requirements and you should choose the right type of nutrients for your vegetable plants.  

You may need to consider what are the best nutrients for indoor growing and for outdoor growing.

Your vegetable plants may also need different types of nutrients depending on the stage of growth that they are at. Seedlings have different needs compared to fruiting vegetable plants.

While you may be tempted to make homemade hydroponic nutrients, it can be complicated to get the right balance of nutrients. It might be a good idea to get pre-mixed nutrients for your hydroponic vegetables, especially if you are just starting.

General Growth

The first type of nutrients that your plants need is for general growth. These nutrients will help the roots of the plant grow strong and healthy while encouraging foliage growth.

The best hydroponic fertilizer for general growth contains higher levels of nitrogen and potassium.

Calcium and magnesium are also very helpful for encouraging general and leaf growth.

5 Benefits Of Using Hydroponic Nutrients for Vegetables

1. Cost-Effective

The hydroponic nutrients for vegetables that you buy in liquid or powder form are usually very concentrated and need to be mixed with water to get the right level of concentration for your plants. 

This means that a little can go a long way and your purchase can last you for a long time.

If you buy an all in one hydroponic nutrient, you will not need to buy multiple nutrients to make sure that your plants’ nutrient needs are met. You also will not need to worry about how to mix hydroponic nutrients.

2. Healthy Roots

Hydroponic nutrients for vegetables will ensure that your plants have strong and healthy roots.

While healthy roots are essential for all plants, they are especially crucial for hydroponically grown vegetables as they will need to absorb all the nutrients that are needed from the water.

The best nutrients for hydroponics that are important for root growth are phosphorous and potassium.

3. Leaves

Healthy and abundant leaves are important for most plants but they are extra important for leafy vegetables that are planted hydroponically.
