For hydroponic growers

Most home based gardeners have a healthy disdain for traditional ag-pesticides. For this group, CleanLight has developed a broad assortment of handheld and/or small scale equipment. This allows growers to protect their plants against most diseases without having to resort to chemical sprays.

CleanLight supplies a wall mounted air sterilizer, handheld lamps to protect living plants against disease and equipment to keep nutrient solutions safe and free of diseases.

Our Services

What we do

Since 2005, we assist growers in 30 plus countries in the successful substitution of some fungicides with germicidal UV. We determine which diseases present a problem, and then offer a solution applicable to local conditions. Supplying a UV dosage which eliminates the diseases in question, while still safe for people and plants. We do the installation usually together with a local contractor.

What we supply

We supply much more than ‘lamps’. CleanLight supplies complete crop protection systems. Whether they are simple handhelds for $ 500 or less, or completely automatic robotized systems that treat huge greenhouses on a daily basis, with a price tag of $ 100.000 and more. Most home based growers purchase their systems online at , or via our growing network of retailers nationwide. All CleanLight equipment meets applicable certification requirements such as CE, UL, as well as Health& Safety.

Who we are

We are an entrepreneurial startup with a highly disruptive innovation in the European Food Valley: Wageningen, Netherlands. For the first ten years we had to fight against unbelief and scepticisme craftfully fanned by research organizations and large suppliers of pesticides. Today, the list of committed growers worldwide using CleanLight grows literally every day and has now almost reached 4000 farmers.

1. Is this UV light dangerous for people?

This light is less powerful than suntanning beds or grow lights. Plus when you work with the light in your hand, you are protected against direct exposure because of the built-in safety reflector. So, you stay below the applicable daily dose. Nevertheless, we recommend using the safety glasses which are provided in the box.

2. Is this UV light dangerous for my plants?

If you shine on the leaves for the recommended 2 or 3 seconds per day, than there is no damage to the plants. In fact, your plants grow better if you supply them with this small daily supplement of UV light. Over-exposure can be harmful to the plants. So, do not hang these lamps on a fixed spot. Do not leave the lamp lying around in your grow room, while the lamp is on.

3. Is this method permitted for crop protection purposes?

Since these lamps do not emit any chemicals, they fall outside of the laws regulating pesticides. This is viewed as a mechanical method for crop protection. This is one important reason why more than 3000 growers are already taking advantage of this truly non-chemical crop protection system.


4. How often do I need to "spray with CleanLight" ?

Most growers spray once a day. That gives the plants a good boost. That gives diseases such as powdery mildew a good bite. Some growers apply CleanLight both early in the morning and again at the end of the day. So, they effectively "spray" twice a day. While those growers invest more time, they also achieve an even better result.

5. In which crops is CleanLight being used?

CleanLight is being used successfully to protect more than 20 crops, such as rose, medical cannabis, strawberries, lavendel, potatoes, tulips, cabbage, tomato, cucumber, aubergine, etc.


6. Until what stage of growth can I apply CleanLight

CleanLight is not harmful to flowers and leaves no residue. This is why CleanLight can be used to protect flowers until the day of harvest. In fact, some growers also use it in the post-harvest stage to prevent losses during the drying process.
