Great finding yep we have a small garden in the backyard of our house usually our gardener take care of plants but when he is on vacations then we have to take care of them i love watering plants so i do but i usually do this in morning and evening not in day time because my baba says in day time watering is not good it might be cause of wilting plants. well it is indeed cool innovation at least now we can figure out our plants are thirsty they need water :p
