10th Annual State of the Cannabis Lighting Market Report (2025). 185 commercial cultivators surveyed by Readex Research. 77% report 50+ g/sqft; 57% report 80+ g/sqft.

Read article →Grow room efficiency is not one number. It's the interaction of four metrics that together determine how much flower you produce, how much it costs to produce, and whether your operation can survive wholesale price compression. The scorecard above measures all four. Here's the context behind each one.
| Metric | What It Measures | Top Performer Benchmark | Why It Matters |
|---|---|---|---|
| Grams/sq ft | Canopy utilization | 60+ g/sqft | Are you filling the room? |
| Lbs/light | Fixture performance | 3.0+ lb/light | How hard is each light working? |
| Grams/watt | Energy efficiency | 2.5+ g/W | How efficiently are you converting electricity to flower? |
| Turns/year | Operational throughput | 5.5+ per room | How fast do rooms cycle? |
The four metrics are not independent. Improvements in one often improve others. For example, better canopy management (filling the room more uniformly) improves both grams per square foot and pounds per light simultaneously. Faster turnaround times compound with yield improvements because you're harvesting more often at a higher yield per harvest.
The 2025 Cannabis Business Times/Fluence cultivation benchmarking survey (185 growers) found that operations scoring in the top quartile across all four metrics had an average cost per pound 40-55% lower than operations in the bottom quartile. That's not a small difference. At scale, it's the difference between a profitable operation and one that's bleeding money.
Based on published survey data and cultivation research, the most common efficiency gaps in commercial cannabis operations are:
Underperforming canopy fill. Many operations lose 15-25% of their potential yield to uneven canopy development, empty space under lights, or inconsistent plant sizes. The data shows up in grams per square foot: if your number is below 40 g/sqft on modern LEDs, there's significant room to improve canopy management.
Slow turnaround between harvests. Every day a room sits empty between harvests is a day it's costing you rent, electricity (dehumidification and climate control), and labor without producing anything. Top operators run 5-6 turns per year per room. If you're below 4.5, the turnaround gap is likely costing you more than you think.
Yield inconsistency between runs. An operation that produces 2.5 lb/light one run and 3.2 lb/light the next has a higher average than one that consistently hits 2.8. But the inconsistent operation has a higher effective cost per pound because fixed costs are spread over unpredictable output. Check your yield consistency to see how much variation is costing you.
The scorecard above shows where your operation sits relative to industry benchmarks. The most useful next step is focusing on whichever metric scores lowest, since that's where the most improvement is available with the least effort. A facility running 50 g/sqft and 4.0 turns/year will see more dollar impact from improving canopy fill than from trying to squeeze an extra tenth of a gram per watt.
