How Much Electricity Does a Hydroponic Tower Use? Real kWh Numbers

Hydroponic tower electricity use concept illustration

A home hydroponic tower uses 0.05–2.5 kWh per day depending on pump and lights: under $1 a month outdoors without grow lights, roughly $8–$13 a month indoors with LED bars running 14 hours daily at US average rates. The pump is the small part — typically 10W on a 15-minutes-on/45-minutes-off timer. Lighting dominates the bill.
