Grow Light Calculator
When working out how many fixtures and the power you need to illuminate your space correctly, follow our simple guide using our grow light calculator.
Aim for optimal lighting of 30w of light for every square foot of space. Use the grow light calculator to get your required wattage. Simply add in your grow room measurements in feet to get an overall square footage. Then enter the square footage into the grow light calculator to get your required amount of power.
Example. 4ft x4ft grow space = 16 square feet = 480w of LED light required
Your result in power can then be matched up to one or more of our fixtures below.
2ft x 4ft (60cm x 120cm) Space
3 ft x 3 ft (90cm x 90cm) space
1m x 1m space
4 ft x 4ft (1.2m x 1.2m) space
