In order to evaluate the effect of the product formula on plants, experiments with plants must be performed. An experiment with the cultivation of Lactuca sativa is currently underway. The results of the experiment will indicate to necessary improvements in the development of the product formula. The greenhouses in the Nature House of the University of Latvia provide suitable conditions for plant cultivation experiments – hopefully, our plants will enjoy the “eternal spring sun”.
The cultivation experiment includes preparation, mixing and filling of the substrate components into pots, seed selection and careful sowing process, seedling diving, regular monitoring and measurements (soil pH, etc.) and, of course, watering.
In addition, it is necessary to understand the behaviour of the product formula in the soil – the duration of degradation, the relationship with soil components, etc. These experiments should be performed under both laboratory and field conditions.
