An introduction to growing cannabis with aquaponics

Aquaponics is a growing technique that combines two efficient systems: Aquaculture, a process of farming fish such as tilapia, koi, or bluegills, and hydroponics, a method of growing plants without soil. When the two are combined, you can create a nearly closed loop system that produces both plants and fish for consumption.

How do aquaponic systems work?

Aquaponic setups are very similar to hydroponic setups, but the source of nutrients for plants is different—nutrients come from the waste of the fish. The plant roots absorb the nutrients and then purify the water before nutrients are returned to the aquarium. Fish food is the only input you’ll need, and this can be grown or purchased.

The primary nutrient produced from fish waste is nitrogen with trace amounts of other minerals. Because of this, basic aquaponic systems are great for vegetative growth, but you’ll need to add additional nutrients like phosphorus and potassium for flowering. This can also be remedied with a double-root zone.

A double-root zone allows you to divide roots into two sections: The bottom half of the pot gets submerged in water, while the upper half of the pot can be filled with soil. This allows additional nutrients to be applied to the roots without contaminating the water.

The two sections can be separated by burlap, which allows roots to travel through while preventing soil from reaching the water. When watering with additional nutrients, avoid oversaturating the soil to keep the water below in the aquaponics system clean.

Aquaponics vs. hydroponics for weed

Aquaponics utilizes a hydroponic setup for growing weed, with the addition of fish in the water chamber. This allows you to skip putting liquid nutrients in plants and instead rely on the waste of fish, a more natural source of nutrients.

The other main difference is the cultivation of fish in addition to cannabis.

Best fish for growing cannabis with aquaponics

Some considerations before choosing fish for your aquaponic setup:

  • Water temperature
  • Tank size
  • Maintenance difficulty
  • Availability

Some fish need warmer water than others, so you may need to invest in a water heater or be sure your setup is in a warm place. Some fish are also bigger than others or more difficult to maintain, requiring more labor or money.

Here are types of fish most commonly found in aquaponic setups because of their low maintenance and versatility:

Advantages of growing weed with aquaponics

  • Sustainability: Aquaponic systems use the waste of one organism to feed another. Fish food manufactured specifically for aquaponic systems ensures your plants will be free of toxins, and the plants will help fish grow strong and healthy.
  • Growth rate: Aquaponics is a great way to grow cannabis plants quickly. By allowing the roots to take in high levels of oxygen they are able to absorb more nutrients and will thrive.
  • Water use: Aquaponics systems use considerably less water than traditional systems because they recirculate water.

Disadvantages of growing weed with aquaponics

  • Initial costs: Setting up an aquaponic system is more costly than a soil or even hydroponic setup.
  • Maintenance: Fish need water in a specific temperature range, so you’ll need more equipment and resources to warm or cool water, and it will require more work to maintain.
  • Algae: As with a hydroponic system, there’s a lot of moisture, requiring you to be on high-alert for algae growth that can harm your plants. Aquaponic systems require cleaning and sterilization to protect plants from algae.

Common challenges when growing weed with aquaponics

Growing weed in a hydroponic setup can be challenging enough, and growing in an aquaponic setup is even more difficult. Growing with aquaponics is not recommended for first-time growers.

Aquaponics can get complicated because you have two focuses: plants and fish, instead of just worrying about your weed plants.

As with growing in hydroponics, using water as your grow medium can be challenging and generally involves more equipment, time, and money.

A tricky thing with aquaponics is being able to balance the fertilizer from the fish that goes into your plants. If growing with aquaponics, be sure to have a firm grasp of nutrients and pH levels, and how to balance them.

How to set up an aquaponic weed garden

The easiest way to start an aquaponic setup is to repurpose an old fish tank and pump. Be sure to dechlorinate the water and allow it to cycle for 4-6 weeks before adding any fish.

Then you’ll need to create a media bed for the plants. Some growers use one big flood tray for a number of plants, and some use individual pots, as in the graphic above.

Then add the fish, and then the plants, and you’re ready to go! Just feed the fish to begin the cycle, and they will create fertilizer for the plants in no time.

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.

Rockwool

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

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.

Aeroponics

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.

Nutrients

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.

Growing Hydroponic Feminized Cannabis Seeds

Growing hydroponic feminized seeds can produce amazing results for cannabis growers. Hydroponics growing methods can produce super fast growth rates, high yields and super clean potent buds. Cannabis thrives in hydroponics, where roots have more access to oxygen, water and nutrients round the clock versus conventional growing methods. A lot of bud farmers greatly reduce veg times by growing in hydroponics; still harvesting very large budded plants for the same flowering times; hydroponics can hypercharge your crops.

Just like there are a lot of great female seed strains to choose from, there are a lot of different types of hydroponic growing methods and systems that you can use. Fact is some are better suited to growing feminized seed strains than others–that’s because female seed plants develop a solid tap root; something cloned plants never have.

Restricting the tap root of a female cannabis seed strain puts a lot of stress on the genetics–just like with conventional feminized seed growing tips HERE. It’s best to avoid putting hard stresses on ANY feminized seed plant, or growers may trigger undesirable traits, including pollination in severe instances.

What are the Best Hydroponic Systems for Growing Female Seeds?

Typically hydro set ups with more space for the root system is best–DWC (deep water culture), RDWC (recirculating deep water culture), large coco pots and similar are ideal. These types of systems have plenty of room for tap roots to stretch out and support large healthy root systems. They are also very productive and save on water and labor.

What are Hydroponic Systems to Avoid to Grow Female Cannabis Seeds?

Smaller sized grow blocks, like rockwool or small pots filled with grow rocks, etc will restrict root development, creating stress on feminized cannabis seed genetics. A 6 inch cube or pot should be considered the bare minimum, provided that plants will be flowered not long after seedlings are established. Larger is recommended.

What are Other Important Things to Avoid with Hydroponic Female Seed Plants?

Avoid wide drifts or big ups and downs with EC/TDS, pH and temperature in the root zone or nutrient solution. In bigger water culture set ups or hydro systems growers may use reservoir chillers during hotter times or may require submersible aquarium type heaters during cooler months. Try and keep roots at a steady 65 to 75 deg F. Wide or frequent swings can put a lot of stress on certain strains and cannabis varieties, with some being more root sensitive than others.
