Aquaponics: A Lighting Guideline
Aquaponics refers to the technology used to cultivate both fish and different types of crop simultaneously. Both species are grown in controlled environments. The fish are taken care of inside water tanks whereas the plants are cultivated through hydroponics. Hydroponics means that the crop is grown without the use of soil. The roots of the plants are submerged in water while the upper parts sit in beds. Read on to learn more about the aquaponics system and the kind of lighting it needs to function.
How Aquaponics Works
Aquaponics workds under notion of one organisms waste is another's treasure, can be observed with the wastes that usually build up inside fish tanks. Generally, the wastes inside the tanks are not favorable for the fish. These wastes should removed and cleaned as quickly as possible. However, the fish wastes are very nutritional for plants and detrimental to their survival. In an aquaponics set up, the main source of nutrients for the plants is the fish waste. Thus, the waste filled water actually flows into the funnels where the roots of the plants dangle. As the plants absorb all of the nutrients found in the waste filled water, they actually help remove the toxins. This in turn cleans the water which can be re-used by the fish, this is the aquaponics cycle. Many experts and professionals have noted the relevance and benefits of using this method.
There are many important components in aquaponics, one of which is lighting. The following considerations should help in setting up aquaponics lighting.
The use of metal halides in aquaponics is highly recommended. This is because this kind of lighting system is efficient enough to produce around 80 to 120 lumens per watt. This means that metal halides allow lesser usage of power while producing more light. the productivity output of the metal halide is ideal for most aquaponics setup. As compared to other lighting systems, the metal halide is considered as one of the most efficient lighting options.
High Intensity Discharge Fixture
There are a lot of people who won’t use High Intensity Discharge Fixture because of its cost. However, what many don’t understand is that the initial cost of the fixture makes up for its utility. In the long run, using it is actually cheaper than other alternatives. This set up uses less power by up to 20 times. You cant expect the same amount of light produced for lower electrical costs.
A comparable option for metal halide is the use of sodium bulbs. Sodium bulbs make use of sodium (excited state) to create light. The use of sodium bulbs allows you to put out more light in the aquaponic set up. Experts also note that these bulbs pose lesser pollution risks than some lighting setup. The only consideration that you should make about sodium bulbs is that their spectrum heavily falls within the end of the spectrum. Make sure you put these considerations into mind before investing on the lighting set up.
