Hi Andrea,
Netro's algorithm is based on expert gardening knowledge, one of which is to avoid watering equally everyday and instead to water less frequently but deeply. We suggest you can allow the moisture level to deplete to a low level (recommended by EPA) before next watering. The estimated frequency 4/5 days will be fine for your plants. For perennial, we suugest water from 70%(low)~90%(high).
Thanks,
Netro Support
