Spread the love

There are so many benefits that you will gain by growing plants hydroponically. Besides having the tent and other accessories, you need to find the top hydroponic nutrients. This will help your plants grow quicker and fuller. You need to have the proper fertilizer and other essential nutrients so that you can harvest the full bounty of hydroponic gardening.

Hydroponic fertilizer is necessary to have for your indoor garden. However, there are so many products on the market and that leads to confusion on which nutrients you need or don’t need to buy.

We advise to use only nutrients that have been tested and approved for hydroponics. As a new grower or even an experienced one, you may not know what to look for and this is the main reason we have put together this guide so as to help you find the best nutrients for cannabis and your other plants.

Benefits of Hydroponic Nutrients

The hydro nutrients help improve the soil or base that is used for hydroponics. These ensure that the plants can absorb all essential nutrients they need to be able to grow in a healthy manner. For instance, nitrogen is not typically available in hydroponics, yet we all know that it is necessary for plants to grow. With the right choice of products, you will enjoy every aspect of your grow tent and, better yet, you end up with higher yields.

What Nutrients to Use for Hydroponics?

When talking about hydroponic plant nutrients, hydroponic fertilizer is crucial. Fertilizer comes in two types: powder and liquid. Knowing the difference between the two forms of fertilizers will allow you to pick the one that suits your needs.

Powder Fertilizer

The powdered fertilizer is typically for commercial and/or experienced growers. This types comes in two parts, one with the main nutrients and the other with the calcium nitrate. The trick with powdered fertilizer is that you have to mix them in the proper quantities to create your solution.

Liquid Fertilizer

The liquid fertilizer is typically the leading type for hobbyists. This design makes it easier to use with your hydroponic system. This mixture is done at the factory–no messing by you! All you need to do is simply apply it to the soil and plants, as per the manufacturer’s recommended instructions.

Which type is the best nutrients for hydroponics? The powder form is cheaper than the liquid fertilizer, even the shipping costs are usually higher since they need to be handled with extra care. This is why the powdered hydroponic fertilizer becomes a favorable option for the commercial growers. It is cheaper and allows you to mix the quantities that you need.

How to Pick the Right Hydroponic Nutrients?

When shopping for hydroponic plant nutrients, you want to get the top hydroponic nutrients in the market. Here are some factors that will help and allow you to get the top hydroponic nutrients.

Type of Fertilizer

As we discussed above, you can choose between the liquid and powder fertilizers. This choice depends on how you want your crops to grow and how involved you want to get.

Typically, small scale growers and hobbyist prefer the liquid fertilizer. With this type, you do not worry about mixing the solution and it is just easier and less messy. For large scale and/or commercial growers with some experience, powder fertilizers may be the way to go. They can be cheaper and come in two parts that you mix together before applying to the plants.

pH Levels

pH levels are important to allow your plants to thrive. Look at the acidity and basic levels of the nutrients before applying any sort of fertilizer. You may need to consult an expert to get the correct pH levels for the plants that you are growing. Often, you local extension office can help with free or cheap analysis tools.

Stage of Growth

Plants go through a life cycle and you should take note of the plant’s current stage before applying the nutrients. The vegetative stage is quite critical and this is one of the stages that plants need the most nutrients. Nitrogen is always necessary to ensure that the plants blossom and grow tall. If your plants are in the flowering stage, cut back on the amount of nitrogen and start providing other nutrients that are rich in phosphorus, potassium, magnesium and calcium.

Electrical Conductivity Levels

Electrical Conductivity or EC levels essential to consider when you are shopping for the hydroponic nutrients for some hardy growers such as cannabis. We believe the best nutrients are ones that have an EC level of around 1200 to 1500 parts per million. Again, make sure to check that you have nutrients that will be in the ideal range so your yields will be optimal.

Synthetic or Organic Nutrients

We have seen two basic typse–synthetic or organic nutrients. Synthetic nutrients seem to be the best for hydroponics because they easily break down into smaller particles. The plants to absorb can then these nutrients. However, this does not mean that synthetics have more nutrients, only that the absorption rate is much faster.

Organic hydroponic nutrients are more ideal for the soil-based gardens. In most cases, this type may have ingredients that can clog the small tubes and pumps in your hydroponic system. However, organic hydroponic nutrients have advantages, it all depends on what you are growing. Synthetic nutrients are said to be the best high performance nutrients for certain plants like cannabis that are nutrient hungry.

Price Factor

It always comes back to this doesn’t it. Let’s be honest, money does not grow on trees. (p.s. If you have one, let me know!) Finding the nutrients that provide the best bang for the buck is important. Since nutrients are a reoccurring cost, you want to be smart about your nutrients and their price.

Wtih all of that, we prefer liquid fertilizer because of the ease of use and mixing.
