Complete Guide To Cannabis Hydroponics: Everything You Need To Know

If you are thinking of growing cannabis with hydroponics is a delicate process that requires special knowledge to grow cannabis properly. First, you should know the basics of this technology. 

Growing cannabis with hydroponics is all about growing your plants faster and healthier and requires almost no work. This article will come in handy if you want to learn how to do it right! 

Let us start with the first thing–what are the major factors that affect plant growth? There are three of them: temperature, light, and water.

Hydroponics uses water instead of soil to support the roots of growing plants. This method gives you more control over the nutrient levels in the water, which is necessary because too many nutrients can kill your cannabis plants. You can use hydroponics to get your cannabis ready for harvest anywhere from 6 to 8 weeks after planting, depending on how much light you are giving them. Temperature control is one of the most important things when growing plants are hydroponics.

Growing cannabis hydroponically (without soil), and grow experts believe that the method is the best way to cultivate cannabis. However, it may seem like a daunting task for those who are new to growing weed. This guide will cover everything you need to know about growing your cannabis plants on a hydroponic system, from start to finish.

Why hydroponics?

The first step to starting your hydroponic garden is to understand what makes it different from other forms of growing. Hydroponics is simply the practice of growing plants in water, without the use of soil. This method has several advantages over traditional gardening, which will be in discussion in the latter part of this article.

Hydroponics is a method of growing plants in water with added nutrients. When using this method in most commercial vegetable farming, and many home gardens, as well. This method is less complicated than traditional gardening and allows you to grow more produce per square foot than with soil-based techniques.

Different Cannabis hydroponic growing system

What are Dripper Systems?

A dripper system is a method of irrigation that uses small, low-volume emitters spacing between at regular intervals along a drip line. These emitters deliver water to the soil near plant root zones. It helps reduce waste by applying just enough water for plant uptake and reduces runoff, soil erosion, and nutrient loss.

Deep Water Culture Systems

The Deep Water Culture (DWC) system is an efficient, very easy-to-use way of growing cannabis. It’s also a lot less intimidating than other systems because there are no bulbs or electricity required. A DWC grow uses about one-tenth the amount of water as the popular NFT method and creates bigger yields with smaller plants. Not only that but it can be done inside even if you live in a cold climate. I’ll explain exactly how to set up your DWC system so you can get started growing right away!


Aeroponics is a type of hydroponics where plants grow in an air or mist environment. In aeroponic systems, I sprayed the roots of plants with a nutrient solution. The major difference between hydro and aeroponics is that hydro requires a growing medium while the aeroponics system does not.


Aquaponics is a method that combines hydroponics, or growing plants in water, with aquaculture, raising aquatic animals like fish and crustaceans in tanks. Aquaponics is often used to raise edible fish and crayfish for consumption by humans.

Ebb and Flow Systems

The ebb and flow system is a type of hydroponics that relies on a water pump to constantly cycle water from a reservoir to a plant bed, and back again. The process allows the grower to increase its growing capacity while using less water. This method is especially useful in an aquaponics system as it provides the fish with nutrient-rich water as well as allowing for year-round production.

NFT Systems

A growing number of hydroponic farmers are turning to alternative forms of nutrient film technique (NFT) and its variations, such as the Deep Flow Technique (DFT). These alternative hydroponic techniques use water and air to provide nutrients directly to plant roots. The system works by flooding a growing medium with a fine stream of water. They pumped air into the water; this creates small bubbles that rise through the solution. The bubbles bring oxygen to the roots, which they depend on for survival in low-oxygen environments like the root zone.

DFT Systems

The deep flow technique (DFT) is the standard hydroponic system used in commercial greenhouse production. The DFT system uses large-diameter net pots to grow the plant roots directly in the flowing nutrient solution, with no medium, such as rock wool or perlite, used.

Finding your growing medium!

So you’re thinking about getting into hydroponics, but you aren’t sure what growing medium is best for your situation? Well, that depends on multiple factors. What are the conditions of your space? Are there any particular restrictions or limits that may apply to your growing environment? Are you using a certain type of plant with specific needs? Is it indoors or outdoors? These are all questions you should ask yourself before deciding on a growing medium. Once you know the answers to these questions, you can start looking at different growing media. There are five main types of growing mediums: Rockwool, perlite, vermiculite, and peat moss. Special to mention, volcanic rock.

  • Rockwool has the most nutrients and holds water well, but it’s difficult to find and is expensive (about $15 for a 2 cubic foot bag). 
  • Perlite keeps the water well and has good nutrient retention, but it doesn’t hold much plant food. 
  • Vermiculite has excellent moisture retention and nutrient retention, making it ideal.
  • Hydroponic peat moss is a recent development in this field and has been successful in the cultivation of indoor plants using hydroponics. They manufacture it from 100% natural materials and comprise long fibers, derived from sphagnum peat moss, which are bound with an adhesive polymer.
  • Volcanic rock is a great product for indoor gardening. It’s easy to use, highly porous volcanic rock that helps increase your yield by providing your plants with water and nutrients. The unique texture of Volcanic Rock allows plants to grow faster and healthier than plants grown in traditional mediums. The plant roots are free to grow into the porous structure of the rock, giving them more access to nutrients and water. The surface area of each piece of Volcanic Rock can be as much as 30 times greater than other substrates used for hydroponics. This means your plants can absorb more oxygen, resulting in stronger volume.

Selecting the right hydroponic nutrients

We should not underestimate the importance of nutrients in hydroponic gardening. It is one of the most important factors when growing plants in a hydroponic system. If you understand how to provide the right nutrients for your plants, then you will have a flourishing garden.

Understanding your plants’ nutrient needs is crucial because if they don’t get enough, they will not grow properly and might die off completely. If you give them too much, they may not absorb all of them or may even get sick from toxic build-ups.

Choosing the right lighting

Many cannabis growers find it difficult to choose the right lighting for their hydroponic growth. With so many options available in the market, it is hard to determine which one will fit your specific needs and budget.

A majority of cannabis growers go for LEDs as we know them for their efficiency and low energy consumption. With their high efficiency and low temperature, they have become a favorite among cannabis cultivators. However, there are a lot of other things that you must consider when choosing the right lighting for your plants.

The issue: we once thought LEDs to be inefficient, but now we know that’s not true. Even those who don’t accept the use of LEDs as an alternative will admit it offers some advantages over HID lamps. The problem is that growing with LEDs is still more expensive than growing with HID lamps. LEDs cost 2-3x more.

LED grow lights are ideal for growing cannabis indoors. The pros of using LED lights over the older style, high-intensity discharge (HID) bulbs are that they run cooler and create much less heat. This is a tremendous benefit because you don’t need a built-in cooling system to keep your plants from getting burned by an HID bulb.

Led lights also have a much longer lifespan than HIDs, which means saving money on replacements and repairs. You can also expect up to 50% energy savings as compared to other lighting options such as fluorescent or HID.

The importance of environmental control systems

Cannabis is a very adaptable plant, but it still needs environmental control systems to thrive. A well-managed greenhouse environment can produce outstanding yields of cannabis that are high in quality,

potency, and consistency.

However, if you are managing the growing area poorly, you could have problems with pests, product damage due to mold or mildew growth, and yields that are inconsistent. Cannabis plants prefer temperatures between 21 and 26 degrees Celsius. 

That is just right in the middle of the typical temperature range for a standard house. Simply means that growing cannabis inside is possible, but you will need to regulate your temperature and humidity levels to ensure that your plants grow properly.

During summer, when temperatures are high, it is crucial to have proper ventilation and good air circulation in your indoor grow room. Under these optimal growing conditions, the plants will produce more flowers and buds with higher THC content than before. Combine this with plenty of fresh CO2-enriched air, and you will be well on your way to harvesting bigger yields than ever before!

What are the benefits of cannabis hydroponics?

Cannabis hydroponics has seen a boom in use over the past few years. We can use it both indoors and outdoors, and it offers many benefits that you won’t find with other growing methods.

  1.  The first benefit is that cannabis grows faster than it would without hydroponics. They keep the roots healthy and alive, so they grow much faster than they would if left to their own devices.
  2.  Cannabis is grown using hydroponics also has higher yields than cannabis is grown using other methods. 
  3.  With hydroponics, you can achieve much higher levels of THC content, as well as better taste and odor.

So If you want to grow high-quality cannabis, pay attention to such details as temperature, humidity, light, ph, and water right from the very beginning of your adventure with this technology. 

Cannabis hydroponics is an amazing way to grow weed, but it isn’t easy. Before you jump headlong into the world of cannabis hydroponics, make sure you know what you are doing.
