What is hydroponic growing?

Best Hydroponic NutrientsGenerally, hydroponics refers to the process of growing plants without the use of soil. Most growers may think of hydroponics as growing in a water bath. However, hydroponics also includes growing your plants in pots or containers using inert growth mediums such as coco, perlite, and vermiculite. When you grow using the hydroponic method, your plants are not able to benefit from nutrients offered by soil. Because of that, you need to give them everything they need to grow through the use of hydroponic nutrients. If your preferred method is growing in a water bath style hydroponic system, you can just add nutrients directly to the water supply. And, if you’re growing in pots you can add nutrients when you water your plants.

Advantages of hydroponics

It Quickens Your Plants Growth

The most notable advantage of hydroponic growing is that it makes the production a lot quicker. When it comes to hydroponics, your plants can grow much faster during the vegetative stage of growth. In fact, it’s believed that plants grown in hydroponic systems grow up to 30% faster than plants grown in soil. This is because hydroponic systems allow you to create a unique blend for the plants so they get an adequate amount of nutrients. In addition to this, unlike soil-grown plants, hydroponic plants don’t need to worry about producing a strong root system. Because of this, they can focus more on growing leaves and buds.

You Have Control Over the Nutrients

Another advantage is that you the complete control of the nutrients that your cannabis will get is in your hands. Because of this, it is easier to fix issues by changing the composition and blend of the nutrient mix.

This is very helpful because it can be difficult to pinpoint the right amount of nutrients cannabis plants need. For instance, when growing in soil, you don’t always know the amount and type of nutrients mixed into it. Hydroponic nutrients usually come in one type so you can control how much each plant gets.

They’re Easy to Use

At first, some might find hydroponics to be daunting, but you’ll find that hydroponic systems are extremely easy to use. All you have to do is fill the system up with water and apply some nutrients. After that, stick your plant into the water. It’s that simple.

Hydroponic Nutrients

Even if you are growing with growstones, hydroponic nutrients will be a crucial and significant factor to consider if you are trying to get and achieve the best yields as much as you can. We all know that soil contains a lot of the nutrients your plants need to grow. So what do we do to give them similar nutrients they could be getting from the soil? The answer is simple, we provide the appropriate and right combination of hydroponic nutrients.

Why choose the best hydroponic nutrients

With the best hydroponic nutrients, you’ll be sure to get the best cannabis in terms of quantity and quality. The nutrient solution you choose to use will then take place of the micro and macronutrients that soil can normally provide. The advantage of hydroponic growing, however, is that you can replicate a soil medium without the unpredictability. What you should look for when purchasing hydroponic nutrients is the ratio of the three macronutrients.


These nutrients are known as macronutrients since they are absorbed in the largest quantities by your cannabis plant.


This nutrient is responsible for leaf growth and pigmentation. When there is a deficiency of nitrogen, older leaves turn yellow and soft. This can lead to a lethal condition if not fixed in a timely fashion.


Phosphorus is the nutrient you’ll need so that stems, roots, and flowers can undergo proper development. The demand for phosphorus increases during the flowering stage so that your plants can produce bountiful and great yields. When your cannabis plants are experiencing a deficiency in phosphorus, the quality and quantity of your buds can be drastically affected. That is why you should be able to provide enough phosphorus for your cannabis plants.


The macronutrient, potassium, is of slightly lesser importance but still contributes to the development of the buds, stems, and roots. It also ensures that proteins are synthesized.

How to tell if my cannabis plants are missing nutrients

There are a few signs you can use to tell if your plants aren’t getting enough nutrients.

Low Nitrogen

The many way to tell if your plants have low nitrogen is if they’re turning yellow, especially toward the bottom of the plant. This usually starts at the bottom and works its way to the top of the plant.

Low Phosphorous

If your plants aren’t getting enough phosphorous, they tend to stay small with very little development. The leaves might also take on a strange purplish-tint or have dark spots.

Low Potassium

Low potassium can be indicated by yellow or brown spots on leaves. This is evident on both old and new growth. In fact, if there isn’t enough potassium, new leaves might start to curl and become crisp. Unlike other nutrient deficiency, if your plant has low potassium, it’s usually more susceptible to pests.

Low Magnesium

Magnesium is important because it helps your plant produce energy. It also encourages them to create enough sugar for rapid growth. Some signs that your plant might have a magnesium deficiency include the leaf tips turning brown, you find you’re not getting a lot of buds, and the leaves veins are yellow.

Low Iron

Iron is one of the most crucial nutrients for plants because it helps with producing chlorophyll. You can usually tell if your plant has an iron deficiency by looking at new plant growth. If you see that these young leaves aren’t growing correctly or quickly die, there’s probably a problem with the plant’s iron levels.

Low Zinc

It’s common for cannabis plants to have a zinc deficiency. This is especially so if you grown them in alkaline soil. Some signs of low zinc include brown spots on the leaves or wrinkled new growth. Low zinc can also make leaves turn sideways.

Low Copper

Cannabis plants don’t need a lot of copper, but it’s a good nutrient for them to have because it helps with their metabolism. Most of the time, low copper amounts can be seen by strange twisting leaf motions. Sometimes the tips of the leaves will also turn brown.

Low Sulfur

Sulfur is essential for healthy cannabis plants. It not only helps with transporting fatty acids throughout the plant, but creates terpenes. If your plant has a lack of sulfur, the leaves will turn a light shade of green or be slow in producing buds.


We know that the wide range of choices may be overwhelming. But we hope that this post has helped you decide on which one will be best for you. Growing cannabis and even other delicate plants will require you to provide the best nutrients you can get. All of these products offer maximum and trustworthy support to your plants. Each of these nutrients is made with specially designed mixes and formulas. They will help keep your cannabis plants healthy while supporting a strong and high yielding produce.
