Estimate the number of grow light fixtures required

Is your canopy covered? Using our grow light fixture calculator, you can easily estimate the number of grow lamps you will need to cover your whole crop in plant nourishing PAR. Don’t come up short, simply enter the required dimensions below and instantly view both the minimum and optimal number of grow lights to cover your indoor hydroponic garden.

These calculations are based on the typical light spread of the specified lamp, mounted horizontally, and matched to its industry standard reflector. It should not be considered a comprehensive light plan. There are various factors that will affect your crops lighting requirements, including reflector shape, crop height, grow room structure, irrigation, temperature, etc.

For professional growers with many lights or multiple grow rooms, we invite you to contact one of the lighting specialists at Hydrotek Hydroponics. We will happily provide custom light mapping and other services to ensure your plants growing environment will be optimized.
