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.
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 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.
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.
Disadvantages of growing weed with aquaponics
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.
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 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.
Aquaponics vs. hydroponics for weed
Some considerations before choosing fish for your aquaponic setup:
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.
The word “hydroponics” is derived from Latin that literally translates to “water working”.
Growing Weed Using Hydroponics
As you can tell, growing hydroponically can get complicated and expensive. That’s why we recommend growing with natural soil, especially for beginners.
Hydroponic weed is the method of growing weed such that each plant grows in a flow or bath of water that is heavily oxygenated and highly enriched with beneficial nutrients . No soil is used in this process, and instead, the plant grows in a sterile, inert growing medium.
All of the nutrients required for the weed to grow are mixed in a solution in the water in which the growth process takes place. This unique method of growing plants took birth over a century ago when it was created by William Frederick Gericke.
