LED Grow Lights: Hydro farming equipment like this utilizes high-efficiency, full-spectrum LEDs, typically consuming only 20W-50W (one-tenth the power of traditional incandescent bulbs) and can be timed to shut down (e.g., operate 12-16 hours per day), significantly reducing power consumption.
Small Water Pump: The circulating water system utilizes a low-wattage pump (approximately 5W-10W), similar to a fish tank pump, operating intermittently (e.g., on for 15 minutes, off for 30 minutes), resulting in an average daily power consumption of less than 0.5 kWh.
Automatic On/Off: Utilizes light and water level sensors and timers to avoid inefficient operation (e.g., turning off lights at night, stopping the pump when the water level is full).
Phased Power Supply: Light intensity is lowered during the seedling stage and increased as needed during maturity, dynamically saving energy.
No High-Power Equipment: Compared to outdoor planting systems requiring pumps (over 500W) or greenhouse temperature control equipment (kilowatt-class), home hydroponic systems consume an average of only 0.5-1 kWh of electricity per day.
| Device type | Average monthly electricity consumption | Monthly electricity bill (at 0.1 usd/kWh) |
| Modular grow box | 6-14 degree | $ 0.6-1.4 |
| Multi-level vertical hydroponic tower | 12-20 degree | $ 1.2-2 |
| Solar integrated system | ≤5 degree | $0.50 |
