         The goal is to automate activities related to the cultivation of plants. <br> <br>
 
         And thus to minimize the associated repetitive tasks and optimize the process. <br> <br>
 
         It's simple. And should also remain so if you have little time for it. <br> <br> <br>

         It should not be necessary to check if the plants need water. <br>
           - Watering should be done automatically but only when necessary. <br><br>
