Grow room electricity cost calculator for hydroponics and indoor growing
This grow room electricity cost calculator helps growers estimate the running cost of lights, extraction fans, humidifiers, dehumidifiers, heaters, pumps, and other electrical equipment used in hydroponics, indoor growing, greenhouse production, and grow tents. It is useful for planning operating expenses, comparing equipment efficiency, and choosing a more cost-effective setup.
The calculator can estimate simple equipment cost in easy mode, break down total grow room consumption in advanced mode, and show monthly energy usage for more practical cost planning.
How this electricity cost calculator works
The calculator converts wattage and runtime into kilowatt-hours, then multiplies the result by your electricity rate. This gives a practical estimate of what the equipment costs to run over a day, month, or custom period.
What each parameter means
- Equipment power: wattage of the device or group of devices.
- Hours per day: daily runtime of the equipment.
- Electricity rate: price paid per kilowatt-hour.
- Daily energy use: energy consumed in one day.
- Monthly energy use: total energy consumed across the selected month or period.
Why electricity cost matters for growers
Running cost is one of the biggest practical factors in indoor growing. Lighting, extraction, heating, cooling, humidity control, and pumps all affect total operational expense. Estimating electricity use helps growers budget better, compare equipment options, and understand how changes in runtime affect total cost.
This can be especially useful when comparing LED fixtures, extraction systems, dehumidifiers, and climate control strategies.
How to reduce grow room electricity use
Lower running costs usually come from more efficient lighting, better environmental control, improved insulation, smarter timer scheduling, and equipment that matches the actual size of the grow room instead of being oversized.
Looking only at wattage is not enough. Total runtime and device efficiency both matter.
Best practice for growers
- Calculate lights, fans, pumps, and climate devices separately for a more realistic result.
- Use real runtime averages instead of assuming all devices run 24 hours a day.
- Compare efficient equipment before buying, not only purchase price.
- Track energy use over time as your lighting schedule changes between veg and flower.
- Use the calculator together with light planning and climate planning tools for a fuller cost picture.

About us. Our 9 year history
GoToGarden started in 2017 out of personal frustration. Our founder was a hobby grower who spent hours navigating online shops that felt built by people who had never touched a plant — cluttered layouts, vague product descriptions, no real guidance on what to actually buy or why. He knew there had to be a better way.
