How to Grow Cannabis Seeds Hydroponically

How To Grow Cannabis Seeds Hydroponically – Hydroponic cultivation is a promising solution to many challenges of crop production. It fixes the need for arable land, deforestation, ecosystem degradation, climate changes, and other issues related to cannabis cultivation. For decades, hydroponics has proven its effectiveness in various settings, and cannabis farming is no exception.

What Is Hydroponic Cultivation?

Hydroponics is a method of cultivating plants without soil by using mineral nutrient solutions in an aqueous solvent. In hydroponic cannabis cultivation, farmers plant their seeds in inert growing media and then supply them with nutrient-rich solutions like oxygen and water. To ensure that the plants remain healthy, farmers must control the whole environment, including nutrition, lighting, temperature, humidity, and oxygen. This system encourages rapid growth, high yields, and top-quality cannabis.

How to Grow Cannabis Seeds Hydroponically

To achieve successful results in hydroponic farming, cannabis growers must become acquainted with every component that ensures a smooth and efficient hydroponic grow. This includes selecting a grow medium, hydroponic system, lighting, nutrients, and more.

Choosing a Hydroponic Growing Medium

The first step to growing cannabis seeds hydroponically is to choose a growing medium. The medium allows roots to access nutrients in the water easily. There is an array of growing media to consider, but the right medium depends on which hydroponic system you will be using. Some of the most popular media include:

Clay pebbles

Clay pebbles, also known as hydroton, are great at aerating cannabis root zones. These particles have large pore spaces, allowing the nutrient solutions to flow through the medium easily. Their large pore size also reduces the chance of blockages within the hydroponic system. Clay pebbles are set up by simply placing them in the container and creating gaps for easy root penetration into the water.

Clay pebbles are a popular choice for small-scale growers; however, this type of medium might be too costly for larger operations. Another drawback is that farmers sometimes need to adjust the pH of the medium to provide an optimal growing environment.


Made using basalt rock and recycled slag, Rockwool is a type of mineral wool that is a popular medium for cannabis cultivation. Rockwool is excellent for water retention, allowing for adequate hydration of the upper root system. This medium also provides exceptional drainage, preventing the plants from becoming overwatered. Although Rockwool is a popular medium that offers many benefits, it is not environmentally friendly and requires pH adjustment for optimal plant growth.


Perlite is a volcanic glass that expands when exposed to high temperatures. This medium is affordable and easy to use, making it a popular choice for hydroponic and soil growers alike. Perlite provides adequate aeration and prevents compaction in garden soil as well as hydroponics.

This medium does not degrade or decompose and can be reused multiple times before it starts to break into smaller pebbles. Perlite has a neutral pH and will take on the pH of the nutrient solution it is submerged in, making it easy for growers to regulate the acidity or alkalinity of their media.

Coco Coir

Coco coir is made from the hairy fiber on the outer shell of coconuts. This type of medium allows for proper aeration and moisture retention in hydroponic systems. It also protects roots from the harsh effects of plant-stimulating hormones. Coco coir is environmentally friendly, has a neutral pH, is reusable, and does not allow for the growth of fungi.

Choosing a Hydroponic Growing System

Most hydroponic systems are similar in their use of nutrient-rich water solutions; however, they differ depending on the material used, setup, water exposure, and circulation. Still, farmers can go for DIY systems using buckets, pumps, drills, and air stones. The best hydroponic systems to consider are:

Deep Water Culture (DWC)

Deepwater culture is a cheap and easy way for beginners to grow cannabis seeds hydroponically. To set up a DWC system, growers simply place their plants in buckets filled with nutrient-rich solutions and use air pumps to supply oxygen to the roots.

Because this system does not use a growing medium, it prevents pests from proliferating around the root zone. DWC systems are fully automated and require little maintenance to use, making them ideal for inexperienced growers or those with large-scale operations.

Ebb and Flow

This system consists of buckets hung over a growing tray with inlet and outlet waterways, both of which connect to an external tank. The tank periodically supplies the plants with fresh water that is rich in nutrients and oxygen. The system has a water pump and a timer to control the water cycle to and from the external tank and growing tray. Ebb and flow systems are ideal for beginners as these systems are highly effective, easy to use, and require minimal maintenance.

Nutrient Film Technique (NFT)

With the nutrient film technique, plants absorb nutrients and oxygen from a solution that flows through growing trays. The tube that circulates the solution is tilted slightly to allow the water to flow from one side of the reservoir to the other. With this system, crops receive a constant flow of nutrients and oxygen. Growers can conserve water and nutrients by using the nutrient film technique because the nutrient solution is constantly being recirculated.

Drip System

A drip system is a type of irrigation method that slowly drips nutrients and water into the roots of the cannabis plants. This system consists of a large tray with a growing medium such as clay pebbles or perlite. Cannabis plants access the constantly flowing solution through individual pipes, and the excess solution drips down the growing medium and back into the reservoir. Because drip systems slowly release water to the plants, it reduces the amount of water lost due to evaporation. This system is also very energy efficient, as it does not require a great deal of pressure from a powerful pump.

Wick System

Much like drip systems, wick systems use growing trays that are filled with clay pebbles. A water tank rests underneath the tray from which several wicks connect to the medium. The solution travels down the wicks, passively hydrating the roots of the plants. This type of system is entirely passive and does not require any pumps or air stones. Wick systems allow the plants to access only as much water as they need, meaning that growers need not worry about overwatering their crops.


In aeroponic systems, plants are suspended inside of a chamber, and their roots are misted with water. Aeroponic systems are often used to start clones but can also be used throughout the entire growth cycle. This type of system may not be ideal for inexperienced growers, as it takes some expertise to set up and maintain. This system also makes it easy for pests and diseases to take hold in the garden.

Choosing Lighting

In the past, most farmers preferred to use high-intensity discharge lights (HIDs) such as high-pressure sodium (HPS) or metal halide (MH) lights. But the recent full spectrum light-emitting diode (LED) grow lights have had tremendous success.

MH lights are close to natural lighting and are abundant in blue and green spectrums, which are best for vegetative growth. HPS offers orange, amber, and red-light spectrums, which are best for later cannabis flowering stages. Farmers often use metal halide lights during the vegetative growth period and switch to high-pressure sodium lights during the flowering period.

Although HID lamps provide an excellent light source for plant growth, they waste lots of energy and produce excessive heat. To mitigate the heat, farmers should invest in robust ventilation systems, including can fans and oscillating fans.

Lately, many growers have started using full-spectrum LED lights, which are far more energy-efficient than HID ones. Moreover, they are perfect for all growing phases and don’t require a ballast to power them.

Because most strains of cannabis are photoperiod-dependent, farmers should carefully regulate the light cycle during the vegetative and flowering stages. This is a crucial step in growing cannabis seeds hydroponically.


Like other crops, cannabis requires an abundance of major nutrients, including nitrogen, phosphorus, and potassium. Additionally, it requires smaller amounts of other nutrients such as boron, sulfur, calcium, magnesium. The best way to feed cannabis plants is to use hydroponic nutrient solutions containing all the required nutrients for the vegetation and flowering periods.

I use general hydro nutrients and have found that because the ppm of my water is below 50 I have to add small amounts of vsma and so to get the best results in my deep water system. A ppm meter is very important to a hydro system.

A Beginner’s Guide To Grow Hydroponic Cannabis Seeds

The magical cannabis plant is known by different names, but the one that stands out the most is ‘weed.’ It gets the name from its uncanny ability to grow easily under varying conditions. It has led to the popularity of a new gardening style of cannabis called hydroponics. Everyone from beginners to cannabis experts is trying this unconventional method on account of its many benefits. While some people prefer growing cannabis in soil, there is a whole class of growers known as hydroponic cultivators.

Are you planning to use hydroponic to grow cannabis seeds? Do you wonder where you can begin? Here is a complete guide on cultivating hydroponic cannabis as a beginner.

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

Final Thoughts

If you are interested in growing cannabis, you may have already heard of the term ‘hydroponic.’ This style of cultivating the green herb is becoming increasingly popular as it improves the yield and speed of growth. More than efficient, growing cannabis with a hydroponic system can be fun and enlightening as you learn a new cultivation method. If you are a cannabis enthusiast and plan on growing cannabis, it is time to start with the hydroponics system.

Top 5 cannabis seeds to grow in hydroponics

The majority of cannabis strains will grow well in hydroponic conditions. When cannabis hydroponics is done well, the optimised conditions offered can allow hydroponics to outstrip growth rates from just about any other cultivation method assuming other factors (lighting, nutrient management etc) are well controlled. But which cannabis seeds will really shine in a hydroponic grow and why? Which cannabis genetics have the breeding and potential to produce XXL yields of resin drenched buds? Read on to see some great pictures of the best cannabis strains enjoying life in the hydroponic fast lane.

What is hydroponic cannabis growing?

Hydroponics is a type of horticulture used for growing cannabis and other crops. Specifically, hydroponics is a form of hydro culture which involves growing plants/crops without soil. Instead the mineral content of the nutrient solution provides the necessary food for plant growth. The cannabis roots may be held in place with clay pebbles, perlite or other inert support materials and may have their oxygen needs boosted by being bathed in a stream of air bubbles.

Best cannabis strains for hydroponic growing

All the Dutch Passion cannabis strains can be grown in hydroponics with great results. But some cannabis seeds can deliver quite exceptional results when the hydroponic cannabis conditions are really dialled in and optimised. The best cannabis strains for hydroponic growing show intense growth vigour. Get the lighting conditions optimised with a high quality LED grow light and you can see branch-breaking harvests.

Of course it helps if you have the experience to maintain the plants in the nutrient ‘sweet spot’ without over-feeding or under-feeding from cannabis seed to harvest. It also helps to deliver top-shelf results if you can maintain optimised environmental conditions. Get all that right and you can see some genuinely astonishing results. The following strains come with our highest recommendations to hydroponic cannabis growers.

Auto Ultimate, exceptional yields of very high THC cannabis

Auto Ultimate is simply one of the best yielding autoflower seeds ever released by Dutch Passion. She does well under 20 hours of daily light from autoflower seed to harvest. This indoor grow timing schedule also works well for the entire range of Dutch Passion autoflower strains.

Unlike other autos, Auto Ultimate has a slightly longer growth cycle of around 12-15 weeks. Whilst this may be a month or so longer than other autoflowers, the extra time is required for Auto Ultimate to complete production of her extravagant XXL yields. The crystal covered buds grind up into a deliciously scented oily slurry which burns with an audible sizzle. These are high quality buds with powerful stress-dissolving effects which bring a smile to your soul.

The longer cycle time, in combination with the one-of-a-kind XXL genetics, are highly recommended to any hydroponic cannabis grower. Crazy yields don’t infer quality compromises either. THC levels are officially rated as very high (around and perhaps just over 20% THC) and will satisfy the most demanding users.

Auto Ultimate is part of the Classic Cannabis seed family. These strains are established and fully proven customer favourites with several cannabis cup winners amongst the ranks. Auto Ultimate’s photoperiod feminised seed sister is called The Ultimate and also has the same outrageous yields.
