We regularly receive requests for thorough gutter washers for hydroponic production systems. The gutter washers for NFT gutter systems currently on the market often use fresh water that is then lost and wasted. The cleaning results are also mediocre. Limex decided to clearly identify all the advantages, disadvantages and wishes within the industry. We then developed the first NFT gutter washer, which will be put into operation in December 2021.
Gutter washers from Limex for a successful harvest
Hydroculture is a cultivation method with infinite possibilities. If you are a hydroponicist, you know better than anyone how important it is for a successful harvest to clean the gutters thoroughly. Good cultivation hygiene begins with clean starting materials. Our NFT gutter washers will help you remove plant debris, root residues, algae and substrate from your gutters, without using chemicals that could harm your crops.
Removal of Pythium
Prevent the spread of Pythium, a fungus that can, for example, occur in algae in hydroponic production systems. This fungus affects the oxygen level in the water, which can lead to stagnation in plant growth. Our Limex gutter washer thoroughly cleans gutters, so fungi such as Pythium don’t stand a chance. If there is stubborn dirt on floats or gutters, we use a disinfectant such as hydrogen peroxide that is gentle on the cultivation water. This exponentially reduces the risk of spreading Pythium.
Use of chemicals in gutter washers
Although using chemicals produces an ultra-clean result in most cleaning processes, in hydroponic production systems,it is essential that as little chemical residue as possible remains in gutters. Alkaline cleaning agents have the properties to clean gutters thoroughly, but can be harmful to the cultivation water. That is why we primarily use the disinfectant hydrogen peroxide in our NFT gutter washers. To do this, our Limex washing machines are specially configured to dose hydrogen peroxide automatically. In this way, our washing machines safeguard the quality and health of your products.

We use a cleaning principle in which four variable factors are applied in quantities balanced to each other. This method is called Sinner’s Circle. The variables taken into account in this principle are: mechanical action (force), time, temperature and the cleaning agent (chemicals). A good balance between these variables will give the best result. That is why it is important to have your gutter washer set up properly by our technicians.
