- Requires 70°F to 85°F and 50% to 65% RH.
- Lighting remains on 18 hours per day.
- Typically takes up 20% of total cultivation space.
Flower Room
- The final stage before harvest, where plants develop buds.
- Kept at 72°F to 85°F and 45% to 60% RH.
- Lighting cycles shift to 12 hours on / 12 hours off to trigger flowering.
- Represents 70% of the total cultivation area.
Additional Facility Spaces
Aside from grow rooms, cannabis grow facilities require additional spaces for processing, compliance, and operations:
- Irrigation and water treatment rooms – Store and manage fertigation systems.
- Trimming and drying rooms – Prepare harvested cannabis for packaging.
