Enter the total number of lights used, the power consumption of the lights per day (kWh), and the electricity cost ($/kWH) into the Grow Room Cost Calculator. The calculator will evaluate the Grow Room Cost. 

Grow Room Cost Formula

The following formula is used to calculate the Grow Room Cost. 

GRC = L * PC * EC

Variables:

  • GRC is the Grow Room Cost ($/day)
  • #L is the total number of lights used 
  • PC is the power consumption of the lights per day (kWh) 
  • EC is the electricity cost ($/kWH) 

How to Calculate Grow Room Cost?

The following steps outline how to calculate the Grow Room Cost.


  1. First, determine the total number of lights used.
  2. Next, determine the power consumption of the lights per day (kWh). 
  3. Next, determine the electricity cost ($/kWH). 
  4. Next, gather the formula from above = GRC = #L * PC * EC.
  5. Finally, calculate the Grow Room Cost.
  6. After inserting the variables and calculating the result, check your answer with the calculator above. 

Example Problem:

Use the following variables as an example problem to test your knowledge.

total number of lights used = 300

power consumption of the lights per day (kWh) = 150

electricity cost ($/kWH) = 1.25

GRC = #L * PC * EC =  ?
