Do indoor smart gardens save money on herbs?

Eventually yes. A $6 clamshell of basil from the grocery store equals about 3 weeks of growth from a pod costing $3. After the initial hardware investment, herbs cost 50-70% less over time.

How loud are smart garden water pumps?

Most hydroponic gardens have small pumps that produce a gentle hum. AeroGarden models run about 30dB — quieter than a refrigerator. Not recommended for bedroom placement but fine in kitchens.
