How much does it cost to run a hydroponic system?
Small herb garden (100W LED, small pump): $3-5/month. Medium setup (300W LED, tent ventilation): $12-18/month. Large system (600W HPS, multiple fans): $20-30/month. Lights are 80-90% of electricity costs.
Are LED grow lights cheaper to run than HPS?
Yes, significantly. 300W LED (equivalent light to 600W HPS) costs $10/month vs $20/month for HPS at average US rates ($0.12/kWh). LEDs also generate less heat, reducing ventilation costs. Higher upfront cost pays back in 12-18 months.
Can I reduce hydroponic electricity costs?
Use LED lights (biggest saving), match light hours to crop needs (lettuce needs 12-14 hours, not 18), insulate grow space to reduce heating/cooling, use timer-controlled pumps instead of continuous operation.
What is the electricity cost for a 150 sq ft indoor hydroponic setup?
For 150 sq ft with 600W of LED lighting running 16 hours daily: approximately $12-20/month at average US electricity rates. Add $2-4 for pumps and ventilation. Total around $15-25/month depending on your state rates.
