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.

- First, determine the total number of lights used.
- Next, determine the power consumption of the lights per day (kWh).
- Next, determine the electricity cost ($/kWH).
- Next, gather the formula from above = GRC = #L * PC * EC.
- Finally, calculate the Grow Room Cost.
- 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 =** ** ?
