1. Calculate the area of the grow space:

$$\text{Area} = \text{Length} \times \text{Width}$$

2. Determine the number of lights needed based on the type of light:

$$\text{Lights Needed} = \frac{\text{Area}}{\text{Coverage per Light}} \times (1 + \text{Light Loss Factor})$$

Where the coverage per light is:

• 100-200W LED: 4 sq ft
• 200-300W LED: 8 sq ft
• 300-400W LED: 9 sq ft
• 500-600W LED: 16 sq ft
• 800-1000W LED: 25 sq ft
