Hydroponic Systems
Did you know that ozonated water is an excellent way to cleanse and sanitize a hydroponic system? You don’t need to drain the system or spend hours disinfecting everything. All you have to do is pump ozone into the water, and it will kill any harmful pathogens in the system. The great thing about this method is that it can purify both the water and root systems during a growth cycle, avoiding root rot and adding additional oxygen to the plants.
OZONE STERILISATION (OZONATION)
Ozonation involves infusing water with ozone (O₃), a natural gas found in high concentrations in the ozone layer, where it is created by ultraviolet radiation from the sun. It can also be created artificially, and used to sterilise and recycle hydroponic water.
Ozonation requires ozone generators to create ozone gas in the grow room. There are two types of ozone generators (corona discharge and ultraviolet), both of which work by splitting O₂ molecules into individual oxygen atoms. These atoms rapidly bind to O₂ molecules to create ozone (O₃), which is then injected into the water to kill any contaminants.
There are many benefits of ozonation. It is by far one of the most effective forms of sterilising water and reacts quickly to any contaminants. It’s also environmentally friendly, and using ozone in your grow room can help prevent disease and pests on your plants (including spiders and mites). However, ozonation is an expensive process. Ozone is also highly corrosive and—when not used properly—can damage equipment in your system.
HOW TO CHOOSE A WATER STERILISATION METHOD
All of the water cleansing methods we’ve covered in this article offer different benefits. However, they all come with their limitations too. Choosing one sterilisation method over another will come down to your personal preferences, your budget, as well as the availability of the required equipment in your area and the size of your grow operation.
If you’re trying to minimise cost, UV radiation is likely the best option. Both ozone generators and pasteurisation machines are pricey pieces of equipment. They also come with maintenance costs that will increase the overall cost of your entire operation. UV radiation chambers, on the other hand, are cheaper both to buy outright and run over time, making them ideal for budget-growers.
Both UV and Ozone sterilisation are also better suited for larger operations. Heat pasteurisation is much more expensive and better suited for small growers with large budgets. Ozonation also arguably offers the best results, simply because ozone is such a strong disinfectant. Just remember that it can be highly corrosive and needs to be handled with care.
