NATURE DID IT FIRST (AND BEST).
Aquaponics are a very interesting development in the world of permaculture and offer some great benefits and advantages. Let’s take a look at hydroponics and aquaponics to see what they offer, and how aquaponics functions in comparison to hydroponics.
Hydroponics – the ingenious and highly optimized system of growing plants in water. Commercially available nutrients provide all that is needed for the reservoir and after these nutrients have been added the growing begins. This is really great for those who want to hit the ground running.
Careful attention needs to be paid when adding elements to the system though as it needs to be completely sterile. This sterile system uses a flood and drain technique allows for fertigation (fertilization and irrigation at the same time) and optimal water as well as nutrient levels. Of course, there are many supplements available to maintain the perfect nutrient levels, for the right price.
As previously mentioned, absolutely everything that comes in contact with a hydroponic system must be sterilized in order to ensure that pythium, otherwise known as root rot, doesn’t take hold and destroy one’s plants. This fungus is an absolute scourge in hydroponics. The temperature of the system needs to be kept below 70 degrees Fahrenheit. Anything above that temperature and the root rot will have a prime environment.
Regular dumping of the water makes sure that the nutrient imbalances that inevitably developed are controlled. There is eventual build up of the nutrients that are supplied in mineral form, and this needs to be balanced out again. This is tested by checking for electrical conductivity in the water due to all the salts and minerals added. Dumping this water can be tricky if there isn’t a safe and convenient location though.
