The Best Hydroponic Nutrients

Growing herbs, flowers, or vegetables in a hydroponic garden is very economical. You will save water, effort, and time. However, just like for herbs, flowers, or vegetables in soil, you will require the best hydroponic nutrients to get the richest harvest possible.

With thousands of nutrients for hydroponic out there, looking for the best nutrients isn’t an easy task. It can especially be a tall order to a new grower because all elements need to be water-soluble. You cannot use the manure from your compost pit.

You require nutrient solutions. That is why we researched and reviewed the ideal hydroponic nutrients in this post for you and other new growers.

Top 10 Hydroponic Nutrients for 2020

Here is a review of the top hydroponic nutrients on the market today:

General Hydroponics Flora Grow, Bloom, Micro Combo Fertilizer Set

Flora line is the most famous product from General Hydroponics, a reputable brand that has supplied hydroponic products for decades. This set comes with three bottles, namely the micro, bloom, and grow. Why the three bottles? It’s because your plants and their growth stage will need different macro- and micronutrients at different ratios.

Although you can use a single bottle for the entire growing phase, it is better to mix them to bring the best results for your plants. How these nutrients work is clearly shown on the bottles. You only need to mix the liquids from the bottles to fit your individual plant and its growth stage. The product is recommended for weed.

Pros

• A trusted brand
• Perfect for beginners and hobbyists
• Suitable for all hydroponic plants and different growth stage

Con

• Quite expensive

Note: If you are a beginner and knows nothing about hydroponic nutrients, this is the package for you.

FoxFarm FX14050 Big Bloom, Grow Big and Tiger Bloom Liquid Fertilizer

FoxFarm, a firm that has been in business for decades, is reputable as a soil nutrients supplier. However, as the hydroponic growing expanded, the company ventured into hydroponic product production (which are also perfect for use in soils). The firm’s Fx14050 trio line is a three parts package like the General’s one.

With that said, the nutrients formulas, as well as the mixing ratio of their bottles for your plants and their growth stage, are different from the General. Again, the bottles come with clear instructions on how you should mix them, and you can also find these instructions on the company’s website.

Pros

What Are Hydroponic Nutrients?

Hydroponic nutrients refer to all commercially provided plant nutrients that are recommended for plants grown in hydroponic growing or system. A hydroponic system is an approach to growing plants which don’t use soil or dirt; they use mineral nutrients solutions

Plants need nitrogen, phosphorus, and potassium or N-P-K, and other trace components or nutrients to grow. A hydroponic nutrient is a liquid version of N-P-K, with other macro elements and nutrients (secondary) such as trace minerals in different quantities.

These secondary nutrients are often varying degrees of magnesium, calcium, and sulfur. The liquid form of a hydroponic nutrient allows them to be applied straight to the root of a plant. They are mixed with water in hydroponic nutrients reservoirs and applied to the root several times a day.

Note that some hydroponic nutrients come in powder form, although most of them come in liquid form.

Hydroponic Nutrients Buying Criteria

Here are some important things that you should consider when buying your hydroponic nutrients:

Effective or Convenient?

If price and ease-of-use are your two most vital criteria, the one-part hydroponic nutrient might be the perfect choice for you. You don’t need to mix anything. You don’t need to worry about the type of plants you have or their stage of growth.

However, it has a shortcoming in that you don’t give your plants their full potential for growth. It’s not an effective purchase for different types of plants or vegetables. And that’s why we cannot recommend it for you.

If you want the best solution, you should go for a three-part nutrient brand. But that means that you will trade the convenience for control of the hydroponic nutrients by customizing the mix to fit your different plants.

Powder or Liquid?

The liquid nutrients are frequently used by hobbyists and starters as they come premixed and are easy to apply. However, they are more expensive than the powdered ones.

Dry or powder nutrients are more economical since they don’t contain any water in them. They also last longer than the liquid ones. With that said, powder nutrients are suitable for use in commercial greenhouses – that’s when they become even more economical. In addition, they are more efficient if you have enough skill using them and if you grow large plantations.

Just like liquid forms, there are some premixed powder nutrients on the shelves today. These are great choices for hobbyists who prefer powder form and want ease-of-use. All you need to do is add it to the water, stir, and then add to your plants.

Synthetic or Organic?

Many growers prefer to farm the organic way with the hydroponic system. But although organic produces seem great for your health and the environment, they trade with the smells and their soluble problem when dealing with hydroponic growing.

You should also note that most of the hydroponic nutrients on the market aren’t organic. You can only be guaranteed of getting organic nutrients if you buy the organic forms such as fishbone, blood meals, and others and add them to the solution.

Even if the manufacturer states that their product is organic, note that they aren’t 100 percent organic as there are some types of refined minerals added.

But if you get the organic produce for your hydroponic system, they will work tremendously. And trading a little of your hassle for an organic nutrient for your hydroponic garden is 100% worth your time.

Made-for-Hydroponic Products or All-Purpose?

Many manufacturers produce a one-size-fits-all nutrient kit. Do not buy this kind of nutrient. For all-purpose nutrients that producers say to work for all set up whether hydroponic or soil, don’t purchase these. To get the best yields, buy a product that is made for hydroponics. Hydroponic nutrients cater for a specific need.

Choosing the Best Hydroponic Nutrients According to Growth Stage

You need to choose the right type of nutrient according to your plant’s stage of growth.

• Vegetative phase – Your plants will require lots of nitrogen to produce leaves and grow taller.
• Flower or mature phase – Your plants will require more potassium and phosphorus, plus magnesium and calcium to bloom. Give them 15% nitrogen, 30% phosphorus, and 30% potassium or a ratio of 15-30-30 for flowering and fruiting.

The best nutrient products come with instructions for which solution to use for various growth phases of your plant.

How to Mix Hydroponic Nutrients

The best way to mix hydroponic nutrients is to follow the producer’s instructions. Different brands come with different formulas. And it is best to mix them with the instructions you see on the packages, or on their websites.

For beginners, you should try a dosage lower than the one recommended. Adjust it when you become a professional.

Measure EC to Determine the Nutrient Levels

After a while, the nutrients solution will reduce their concentration. That means your plants will lack the required nutrients. You should do an Electricity Conductivity (EC) to determine the concentration of all nutrients of the solution.

It might be difficult to measure the ppm (part per millions) of every nutrient in your solution, but you can know the total ppm of all nutrients easily. It will show the ppm of nutrients in your hydroponic product.

The simplest way to measure ppm is to use an accurate digital ppm meter. Dip your meter into the solution and then take the reading. Generally, EC should be 1000 to 1500 ppm, but it will depend on the plants grown and the age of your plants. You will require higher ppm as your plants get bigger.

Measure pH and Change it Accordingly

The pH level of your hydroponic garden needs to be kept balanced during the entire duration of plants growth so that the plants can receive the right nutrients. Note that if the pH is unbalanced (too high or too low), the vital nutrients will be locked-out and your plants won’t take them. Therefore, monitoring pH changes is vital.

You will know when to adjust the levels of the solutions before your garden and plants suffer.  The recommended pH levels are 6.0 to 6.5. Use a pH meter to determine the pH and adjust the pH accordingly.

Top Tips for Selecting Hydroponic Nutrients

Here are some important tips that will help you to narrow down your choices when buying your hydroponic nutrients.

• Nitrogen, phosphorus, and potassium should be present in the product you want to purchase. They allow your plant to grow healthy and even increase the yield.
• At different phases of growth, your plants will require different nutrients. They require high nitrogen, high or medium phosphorus, as well as high potassium during the vegetative phase. On the other hand, they will require low nitrogen, high phosphorus, as well as high potassium during the flowering stage.
• Liquid nutrients are better than powdered ones as they are very easy to use. Powdered nutrients are complicated when mixing, although they are cheaper.
• If you want to grow organic plants, you should get organic nutrients (they are also environmentally friendly). Chemical nutrients are preferred if you want to get your results faster.

FAQs About Hydroponic Nutrients

Q: How many times should I change my hydroponic nutrients solution?

A:  Most growers recommend you change your solution at least once per week. Use an EC or TDS (total dissolved solids) meter to test the part per millions of your solution to find out if it is getting low or full of salts.

Q: Which is better, synthetic or organic nutrients?

A: There are pros and cons to both synthetic and organic formulas. Some growers argue that organic solutions lead to more clogs and buildup. Some people prefer them because of their health benefits.

Q: What is ppm, and why is it applicable to many things?

A: Parts per million (ppm) is a measurement of TDS in your solution. It is also used to measure the amount of carbon dioxide present in the air of your hydroponic system.

Q: Which water should I use in my hydroponic system?

A: The best water should have low contaminants or salts. Rainwater is often the best although you can use tap water as it is convenient and satisfactory especially if it’s under 0.3 EC. (Read more to Rain Barrel)

The Definitive Conclusion

In conclusion, these are the two questions that you need to ask yourself:

1. What is my budget?
2. What nutrients ratio do I require?

These questions will allow you to determine the best hydroponic nutrients for your hydroponic system and remember that brands also matter.
