What is Hydroponic?

Before delving deeper into cultivating hydroponic cannabis seeds, do you know what it is? Hydroponic comes from the word ‘hydroculture,’ which essentially means growing plants in the absence of soil. Hydroponic cultivation involves growing cannabis plants in nutrient solutions, ideally with a medium like gravel or coco coir, to offer support. While people often use a medium, hydroponic cannabis seeds can grow from nutrient-rich water, with roots submerged into it. 

With hydroponic methods, the cultivators can control the plant’s growth by merely evaluating the water and altering its nutrients. Plenty of nutrients are available in the market today, designed specifically to help you grow cannabis seeds. Much like soil, they have additives that can adjust the pH level of water, so you don’t have to take meter readings or make necessary changes.    

You can grow any cannabis strain with hydroponic. If you are looking for something to boost creativity and social energy, you can try the fruit punch strain. But if you need a relaxing effect from cannabis, opt for the white widow strain.

Benefits of Using a Hydroponic System

Hydroponic methods have emerged as a popular method of sustainable cultivation. It offers a wide range of benefits that make it a popular choice among cannabis growers. Here are a few benefits of using hydroponic cannabis seed cultivation:

1.   Fast Growth

When cannabis plants are grown into the soil, they have to seek out nutrients from it actively. With the hydroponic system of cultivation, nutrients are delivered right into the roots of the plants. They can use this reserved energy on growing plants and leaves, helping them grow at a much faster pace.

2.   More Yield

If there’s one thing that every cannabis cultivator wants, it is more yield. And this method can provide you with just that. Growing cannabis hydroponically will allow you to harvest large quantities of the herb. In this case, you can quickly get 20-30% more yield than the traditional methods of cultivation because you will require less space for each plant. 

3.   Increased Hygiene

Soil can easily attract pesky little creatures that can hamper your plants. Since hydroponic systems are sterile, there are fewer chances of soil-borne diseases and pests with the soil. You can get healthier and more robust plants with fewer issues during the entire cultivation journey on account of the highly hygienic environment. With this method, you can also let go of pruning the plants’ worries since there won’t be any overgrown weeds. Now you can order weed online in Canada and get the most out of it.

4.   Full Control

People often tell beginners that soil is the most forgiving medium to grow cannabis. It implies that they can fix their mistakes quickly and without harming the plants. But, in reality, it can be challenging to control the nutrients of the soil precisely.

It isn’t right in hydroponics since the cultivator has complete control over the water medium in which the plants are growing. They can easily make changes to it to establish the best possible medium for cannabis plants.

Various Types of Hydroponic Systems

When it comes to hydroponic systems, the choices you get are staggering. There are many different systems available today, and it can become challenging to pick the right one. Before you begin with it, it is essential to understand them and then choose the right one.

Here’s your guide to different hydroponic systems that you can use for cannabis seeds:

1.   Deep Water Culture

Deep Water Culture, also popularly known as DWC and reservoir method, is a common way of hydroponically growing cannabis seeds. It is a relatively easy method, making it suitable for beginners. They are affordable and can guarantee you the fast growth of plants.

It gets the name from the fact that the plants’ roots are completely submerged in the solution. The method involves a simple tank and a pump that supplies a nutrient solution by filling the grow tray periodically. Besides that, airlock ensures a proper supply of oxygen for your cannabis plants. With this method, you have to clean the tray and reservoir carefully to keep the environment hygienic.

2.   Aeroponics

Aeroponics is the most advanced and advantageous method of hydroponics available today. As the name suggests, this method involves hanging the plants’ roots in the air. With that, it doesn’t require a medium. Instead, it involves a smart supply of the nutrient solution, which makes it useful. The answer is misted on the roots, which hang in the air. It allows the roots to absorb the solution effortlessly while remaining oxygenated.

The innovative configuration makes it impossible to lose any water to evaporation, and you can easily control the humidity level. Your hydroponic cannabis seeds can grow ten times faster with this method when compared to conventional methods. Cultivators are innovating further and using vertical aeroponics known as tower gardens.

3.   Ebb and Flow

If you are a beginner, another method suitable for you is the Ebb and Flow method. It can be set up and used very quickly and involves a reservoir placed under the growing tray. The soilless growing medium and cannabis plants are put in the grow tray. The medium becomes an anchor for the roots of the plant while providing support.

In this method, the medium gets made from highly-porous materials to retain both air and water. You can easily customize the irrigation level to get the desired results. 

4.   Continuous Flow

The most commonly used hydroponic cannabis cultivation system is the continuous flow method. It involves any technique that provides a continual flow of nutrients to plant roots. But, there are two major types of constant flow hydroponics. They are:

  1. Drip irrigation releases a well-controlled dosage of water and nutrients, drop by drop, to the cannabis plants. Drip irrigation can minimize water loss to evaporation and help people who have a limited water supply.
  2. Nutrient film technique: This method is similar to drip irrigation, but the slight tilt ensures proper supply.

How to Grow Cannabis Seeds with Hydroponic?

Now that you are well-versed with the basics of hydroponics, it is time to implement it for cannabis seeds. Read to find the list of things you need to grow cannabis using hydroponic methods:

1.   Lighting System

The hydroponic system needs similar lighting as soil-grown cannabis plants. While you can use the same light bulbs for the entire growing period, you can get a Metal Halide bulb in the vegetative stage, a High-Pressure Sodium lamp in the flowering stage. For indoor cultivation, you can also use LED lights.

The lights you use can also depend significantly on the size of your garden. Once you have set up the lighting, place germinated cannabis seeds into pots or buckets.

2.   Growing Mediums

When the seeds sprout, you can place them into a growing medium. The medium offers mechanical support to the plants, which is essential for their growth. There are many types of mediums available like:

  • Rockwool
  • Lava rocks
  • Clay pebbles
  • Perlite
  • Coco coir


3.   Right Pot

It is essential to get the right pot as it can decide how much the plants will grow. A large pot will encourage your cannabis plants to grow larger, whereas a small pot will help contain their size and keep it manageable.

4.   Grow Table

The one piece of equipment that will occupy most space in your growing area is a grow table. The table and the tray help contain and then return all the excess water to the reservoir. It will have a low point where all the water collects and goes back to the reservoir before it goes to the cannabis plants. The reservoir is the tank that circulates water through the hydroponic system, and its size must depend on the size of your growth.

5.   Nutrients

You can get nutrients for cannabis plants in both powder and liquid form. The nutrients you use must contain nitrogen, potassium, phosphorus, magnesium, and calcium. If you plan on getting organic flowers, use organic nutrients.

6.   Other Equipment

Besides that, you may need a few other ingredients like:

  • Air pump
  • Airstone
  • Water pump
  • pH and PPM meters
  • Tubing
  • Dripline emitters
