You could adjust the amount of nutrient added to the solution, dilute the solution with water, or add more water to increase the volume of the solution, which would lower the concentration of nutrients.

A container to hold the plants by the collar so that the roots are suspended. The container needs to be slightly sloped and provide drainage points for the nutrient solution to be recycled back to the nutrient reservoir. An automated spray system to spray the nutrient solution onto the suspended roots. The misting portion of the system needs to be housed within the enclosed container. A nutrient reservoir to collect the nutrient solution in. This would normally be equipped with a pump (to spray the nutrients) as well as an oxygenation system to oxygenate the solution. Depending on how sophisticated a system you wanted, temperature, pH and automatic nutrient dosing systems could be included.
The amount of water you add.
Cell Culture
The function of solution A and B is to have a color change to cherry red if nitrites are present in the product.
Hydroponics substitute a nutrient medium in place of soil. for the plants to root and grow. The nutrient medium may be either a water solution or an inert material.
A nutrient solution can go rotten after a few days due to microbial growth, particularly bacteria and fungi, which thrive in nutrient-rich environments. Poor aeration, insufficient sterilization, and exposure to contaminants can accelerate this process. The breakdown of organic materials in the solution can also lead to the production of unpleasant odors and a change in color, indicating spoilage. Regular monitoring and maintaining sterile conditions can help mitigate these issues.
To grow cilantro hydroponically, you will need a nutrient solution, a growing medium like rockwool or perlite, a container with a lid to hold the solution, and a light source. Plant cilantro seeds in the growing medium, place the container in a well-lit area, and regularly monitor and adjust the nutrient solution levels. Harvest the cilantro when it reaches the desired size.
