Have you heard of UV filtered water being used in a greenhouse? When you want to start a greenhouse, you have to think carefully about the source of the water you will use for irrigation.
A greenhouse is primarily used to provide a microclimate that gives your plants the best chance of survival. One of the best ways to do this is to provide clean water.
But, how can you ensure the water you use in your greenhouse is the cleanest you can use? By using UV filtered water!
What is UV Filtered Water?
When water passes through a UV filtration system, the ultraviolet light in the unit penetrates the outer membrane of microbes and kills them. What you end up with is water that has 99% of all microbes removed from it.
Remember that your greenhouse is a microclimate and if you do not use clean water, you will be introducing bacteria and other pathogens to this microclimate and they may be hard to get rid of.
Why Use UV Filtration Systems
While there are other filtration systems you might consider, UV filtration systems stand out for one main reason; they do not introduce any chemicals into the water.
This is achieved through the use of the Ultraviolet light as discussed above. By using UV filtered water, you also reduce the chances of your plants being attacked by pests or diseases.
This saves you a lot of money as you save on pesticide and other sprays. This improves your bottom line if your greenhouse is a commercial entity.
Some other benefits of using UV filtered water include providing a healthy environment for those working in the greenhouse.
It also improves quality of your plants, reduces stress on plants as they do not have to fight pathogens and, not harming biological control agents that can help you fight pests.
Where To Install Your UV Filtration Systems
UV water treatment can be used to disinfect water collected from other sources. In a bid to save water, many people who have a greenhouse opt to collect water from different sources instead of using water from the mains.
These alternative sources include surface water or rainwater. The UV filtration system is installed at the outlet of the collection or storage tank.
By having the system installed here, you are sure all the water getting to your greenhouse has already been filtered. They can also be installed on your piping system so that unused water can be recirculated and reused.
Do note that if this recirculated water has any fertilizer in it, you need to have wipers installed. These help to prevent the build-up of deposits to increase the effectiveness of the UV system.
Choosing the Right UV Filtration System
The first consideration to make is the capability of the water system’s filter. Ideally, you need a water filtration unit that filters a large enough quantity of water for your gardening use.
Next, you need to consider the flow rate. This is the amount of water that can flow through your filtration system.
The flow rate you settle upon will also be determined by the size of your greenhouse. In most cases, you do not need a filter with a high flow rate because your greenhouse will not use as much water as you would use in the house.
But, if you have multiple greenhouses, you will need to calculate the amount of water you will need for all of them and make the necessary adjustments.
The amount of energy released by the UV light source is another factor to consider because you will likely not be drinking water intended for your greenhouse(s).
You will not need a filtration system with a high ultraviolet dose; you will just need one strong enough to get rid of most microbes with the understanding that you might still use pesticides to kill all microbes that remain.
Wrapping Up UV Filtered Water in Your Greenhouse
Lastly, you need to know the quality of the water you will be filtering because different water sources have different types and amounts of contaminants.
In addition, you need to know if the water has a high concentration of bacteria, the hardness of the water, as well as the amount of sediments in the water you intend to use.
Using UV treated water saves money by reducing the amount of pesticides you use, as well as an increase in the quality of your plants and produce due to the reduced number of microbes in the water you use to irrigate your greenhouse.
Although many people might think using UV filtered water in a greenhouse is going too far, there are real benefits to using this water.
