Aquaponics—Integration of Hydroponics with Aquaculture. Aquaponics Systems. Aquaponics Basics. Portable Farms™ Aquaponics Systems. Go green with sustainable aquaponics. Aquaponics is the marriage of Aquaculture and Hydroponics to make a totally organic closed loop system that requires no chemical fertilizers and is environmentally friendly and safe!
With Aquaculture or Hydroponics when the solution becomes unbalanced nutrient rich wastewater is dumped into the environment causing environmental damage With Aquaponics this does not happen, this is a water wise system too! Aquaculture is the raising of fish (in most cases a food fish) as the primary "Crop" The water used in this system will rapidly become out of balance for the fish ie., filled with fish waste...
This waste water is then purged often on an ongoing basis in order to keep the water clean enough to sustain the numbers of fish being raised. This waste water is "Nutrient Rich" in that it is filled with fish waste which is a wonderful fertalizer... This throws the local water way's ecosystem out of balance as it tries to cope with the excess nutrients. The Raft Method. The Raft System An (abbreviated) article from the Aquaponics Journal Lettuce in raft aquaponics As aquaponic technology continues to develop, there are two primary methods that have evolved. The media-filled bed system, which many backyard enthusiasts use, and the raft system, which most commercial growers use.
NFT (nutrient film technique) is a third, less popular method of aquaponics. In a raft system (also known as float, deep channel and deep flow) the plants are grown in floating Polystyrene boards that float on top of water. A media-filled bed system uses a tank or container that is filled with gravel, perlite or another media for the plant bed. In this article, I will discuss the raft method, the advantages and the way it works. One of the unique advantages of the raft system is the high volume of water in the system. Commercial aquaponics, Guadalajara All of these factors contribute to raft aquaponics being the choice for many aquaponic growers. Closed Environment Agriculture.
CEA - Closed Environment Agriculture By Erik Biksa A closed growing environment differs from the traditional grow room set-up in that it does not "connect" to the external environment and runs on a closed loop. Typically, grow room air is vented to the outside while outside air is drawn in to replace the air being evacuated. This creates an "open door" for a host of problems, and can limit the amount of control you can take over your growing environment. The open loop can be equated to greenhouse growing, except for the fact that you are supplying the light. In this scenario you are subject to the limitations, pests, and problems of a greenhouse environment.
The following model should give the grower some insight on some key features in a closed-loop growing environment. Ideally there are three rooms of about equal volume. The central room will usually hold the HID ballasts, although they may also be located in another area. In our example each room has about 10' X 10' of linear space. Salvari - Introduction. The Theory The following diagram roughly summarises the theory of Aquaponics.
Essentially the fish and the plants have a symbiotic relationship. Organic Aquaponic Gardening in the SF Bay Are. Free pvc greenhouse plans. Greenhouse Assembly: This 6x9 ft, pitched-roof kit greenhouse can extend the growing season on your farm or in your garden.
