The Complete Aquaponics Guide For Growing Cannabis

Aquaponics for cannabis is the cultivation of marijuana without soil. This technique combines hydroponics and aquaculture to provide an efficient, eco-friendly way to grow cannabis. In a hydroponic system, a weed crop grows with only the use of water, nutrients, light, and air—without soil.

Aquaculture systems involve farming aquatic creatures such as koi or tilapia in tanks in order to feed them certain food sources. The waste from these marine animals can then be used as food for plants; this is known as an aquaponic system which includes both hydroponic and aquaculture elements.

In an aquaponic system, water is recirculated between two tanks with fish living in one tank and plants growing in the other. Waste produced by the fish provides essential nutrients to be absorbed by the plants; this waste also acts as a fertilizer.

The plant roots absorb the nitrogen-rich fish waste, which stimulates their growth and nourishes them. Organic matter such as vegetable scraps are added to increase bacterial activity which helps break down dissolved wastes into nitrates that react favorably with cannabis plants’ root systems while still maintaining optimal pH levels for growth in water tanks.

A cannabis aquaponic system is an excellent combination of hydroponics and aquaculture that can produce high quality marijuana. The key to getting the most out of this type of system is understanding how it works, which starts with its life cycle.


Fish are one of the most fascinating creatures known to humankind. They can be found in both marine and freshwater habitats, and they play a pivotal role in maintaining aquatic ecosystems. In an aquarium or rearing tank, fish add life and color to the environment, while their waste serves as additional nutrients for algae and plants growing within the tank.


The aquaponics cannabis system is gaining popularity as a sustainable and cost-effective approach for growing marijuana. Aquaponics combines the cultivation of plants in water with fish, such as tilapia or koi, living in the same body of water.

Nutrients from the fish waste are used to nourish the plants, while the plants cleanse and purify the water that supports common fish life. This symbiotic relationship between aquatic creatures and plants is perfect for growing strong, healthy cannabis crops.


Bacteria play an essential role in the success of aquaponic systems. They provide a critical service by converting the waste produced by fish into nitrates, which are a form of nitrogen utilized by plants for oxygen and proper growth. This process is known as nitrification and occurs when bacteria living in the biofilter oxidize ammonia from fish waste into nitrites before further oxidizing them into nitrates.

Biofilters extend the surface area of an aquarium or tank, providing much-needed space for beneficial bacteria to colonize and grow in order to effectively convert toxic ammonia from fish species waste into nutritive nitrates.

Adopting aquaponic weed cultivation provides an advantage in terms of rapid plant growth. This is due to the system’s ability to provide the roots of the crops with adequate minerals and vitamins, promoting strong and healthy growth. Furthermore, aquaponics is more water-efficient compared to traditional growing methods, as regular hydration is not required, leading to a significant reduction in water usage.

Pros Of Growing Cannabis With An Aquaponics System

Pros Of Growing Cannabis With An Aquaponics System

One of the most prominent benefits of growing cannabis with an aquaponics system is its organic nature. Multi-trophic symbiosis ensures that cannabis plants get healthy and happy. The water circulated in the aquaponic tanks contains rich nutrients to give the crops their desired potency and flavor. Its remarkable yields per plant deliver higher yields, thus resulting in more harvest per effort than any conventional cultivation method.

Moreover, there are several factors that make aquaponics more effective for growing weed than other cultivation methods. One does not need to monitor and adjust the nutrient levels constantly, as is done in hydroponic systems. This saves time and effort which can be invested elsewhere comparatively.

Cons Of Growing Cannabis With An Aquaponics System

Growing cannabis using an aquaponics system has some drawbacks, namely the high startup costs and the need to learn two sets of skills in order to set everything up correctly. For beginners, the initial outlay for setting up an aquaponics system can be quite costly, as not only is equipment such as pumps and filtration systems required but also fish tanks that are suitable for growing aquatic species.

Additionally, it is important to research what hydroponic weed strains will best suit the specific environment so that they can flourish when established. This means that beginners need dedicated time to research and learn the basics of fish farming before they can get started on their aquaponics journey.

How To Set Up a Cannabis Aquaponic System

How To Set Up a Cannabis Aquaponic System

If you already have a hydroponics or aquarium system, you’re on the right track for growing cannabis using aquaponics. To maximize plant growth, consider adding a “dual root zone” to your setup. Clay pebbles alone may not provide adequate nutrients for both microbes and aquatic creatures.

A dual root zone, on the other hand, creates a soil layer that is rich in minerals to enhance plant development. Here are the steps to set up your cannabis aquaponic system:

Step 1: Put Your Fish Tank Together

Having an aquaponic fish tank is a great way to grow plants and fish at the same time while keeping both eco-friendly. The first step in setting up an aquaponic system is purchasing the right tank. Depending on the space that you have available, and the type of aquatic creature you wish to introduce into the tank, there is a range of tanks out there that could provide a perfect fit for your needs.

An acrylic aquarium with dechlorinated water is a popular choice for most setups as it allows for a safe, comfortable environment for all types of fish or other aquatic creatures. Dichlorination of tap water can be done by leaving it to sit for at least 24-48 hours before introducing new species into the aquarium.

Once it has been properly dechlorinated, let the tank run empty for 4-6 weeks in order to achieve optimal levels of nitrate and ammonia. This will help ensure that your aquatic ecosystem can thrive when added elements are introduced.

Step 2: Prepare The Media Bed

Creating a media bed for cannabis growing requires careful planning. The first step is to choose an appropriate tray or container, such as a large wooden or heavy-duty tray, and place it on a flood table above the sturdy fish reservoir.

Next, introduce a layer of clay pebbles – a popular pH-neutral substrate layer free of nutrients- over the tray. This will create an optimal environment for the weed crop’s roots. On top of this layer, you should then add another absorbent material such as burlap membrane cloth to make up the dual root zone.

Finally, cover this all with a layer of pH-balanced soil in order to support healthy growth throughout your crop’s life cycle. Following these steps will ensure the development of strong, healthy plants that can thrive in this nutrient-rich environment.

Step 3: Choose And Add The Fish

When it comes to choosing fish for an aquaponic system, there are some popular options available. Ornamental marine animals such as tetras, koi, guppies, goldfish, and mollies make up the majority of these fish – they are great for aquaponics due to their resistance to diseases and their relatively easy management.

In addition to these ornamental sea creatures, barramundi is also a great choice due to its rapid growth rate and vigor. Tilapia is also renowned for its resistance to parasites as well as its ability to thrive in different temperatures and water challenges, making it perfectly suited for thriving in an aquaponic environment.

Ultimately, the type of fish you choose will depend on the size of your system but with these popular choices, you can’t go wrong when selecting the ideal fish for your aquaponics setup.

Step 4: Transfer Weed Plants

Transferring your germinated marijuana plants to the chosen system is an essential process in order for healthy growth. To start, make sure your reservoir is filled enough so that the plant roots can be completely submerged underwater.

If growing outdoor marijuana seeds, place a layer of stones or gravel at the bottom of the tank before submerging the root ball and connecting it to a pump which will spray small amounts of nutrient solution aerially around the roots.

It’s important to have just two nodes appearing on each seedling before starting transplantation because any more could cause damage throughout their fragile systems.

Step 5: Maintain An Aquaponic System

Maintaining an aquaponic system for growing marijuana requires regular monitoring of certain parameters to ensure the health of all the components. Water quality is especially important in aquaponics and it needs to be tested regularly to check for nitrate levels (3–150mg/33.8 fl. oz.), temperature (64–86°F), pH level (6.8–7) and dissolved oxygen (5mg/33.8 fl. oz.).

An aquarium test kit such as a liquid test or even an electronic analyzer can be used to gather information on these significant parameters and act accordingly if any changes need to be made.

It is also necessary to pay attention to ammonia levels which should remain low, below 0.3ppm, in order to keep the fish healthy and thriving in its environment. Regular filter maintenance is needed as well so that accumulated waste does not stunt growth or cause any issues with water chemistry balance.

Nutrients must also be monitored carefully since too much can cause algae to bloom and leave weed plants without proper nourishment; avoid over-fertilization if possible since it can ultimately harm fish.

In aquaponic systems, happy plants benefit from an environment with no soil pests or need for pesticides, that provides necessary nutrients for maximum growth. Aquaponic marijuana has the additional benefits of unlimited access to oxygen, nitrogen, and other beneficial minerals which can enhance its growth significantly.

Furthermore, the nature of this system allows for greater control over water acidity and mineral content as needed by the plant. This control combined with faster access to nutrients provides a great environment for faster-paced development of crops than traditionally found in soil-based processes.
