Power, watering and climate in a minute
Three quick calculators for your grow tent. They answer one question right away. The app keeps calculating every day, matched to your grow.
What does your grow tent cost in power?
Enter up to three devices with watts and hours per day. For lamps you can set separate hours for the flowering phase. Results update instantly.
| Device | Watts | Hrs growth | Hrs flowering |
|---|
Three devices fit here. In the app you can add as many as you like.
Your price per kWh is on your electricity bill. Standing charges are not included.

How to save power in your tent
Measure the real wattage
The wattage on the box is often the maximum. A plug-in power meter shows what your lamp and fans really draw, dimmed too.
Use your own price
Your bill shows the price per kWh. With exactly that value, the amounts in euros are right.
Plan light hours per phase
Many plants get more light hours in growth than later. Fewer hours in flowering cut costs noticeably, in the example by almost a quarter per day.
Count the small devices
A 20 W circulation fan runs around the clock and uses 0.48 kWh a day, almost as much as a 150 W lamp in three hours.
Know the total in advance
Sprouto estimates consumption until harvest from your device plan, split into growth and flowering, and shows it week by week.
All automatic in the app
Enter it once and Sprouto keeps counting every day, matched to your plants’ phase. No spreadsheet, no calculator.
Every kilowatt-hour in view
The “Power” tab shows usage and costs without any maths.
- Today, 7 days, 30 days and since start, in kWh and euros
- Forecast until harvest, so far and still to come
- A bar for every grow week, planned weeks lighter
- Device list with watts and hours, flowering hours per lamp
Ready in three steps
Set up your grow
Choose plant, start, substrate and watering rhythm. It takes about two minutes, even for a grow that is already running.
Tick off daily
Sprouto shows what is due today. Tick it off, enter values or simply say what you did.
Understand and improve
History, photos and power costs show what works. Next grow, you know better.
