Ogrodnictwo Dziubek is a producer of greenhouse tomatoes appreciated by consumers and recipients, a family company from Koźminek near Kalisz, which has been growing tomatoes for almost 20 years. Currently, the cultivation is 11 hectares under glass.

In 2013, the company built modern greenhouses in Nowa Nakwasina with a total area of ​​5 hectares with cultivation gutters and a double shading system.

The annual harvest of the entire farm is about 3,000 tons of tomatoes.

It was here, in the Nowa Nakwasina greenhouse, that it was decided to test Nano-water or declustered water, which, according to research, would allow them to grow healthier. The nano-water is produced in special chambers developed in Bolesławiec by Stomadent and Nantes.
Thanks to the water declastization chambers located in the containers, the water can be processed directly at the food manufacturer.
Such a container was sent to Nowa Nakwasina and installed in the facility. 250-300 cubic meters of water are used daily here in the summer cycle. This water is now passed through the declastization chambers, which changes its properties and is supposed to help plants. The chambers only change the structure of the water, they do not interfere with its chemical composition.
