Fluffy/Larfy Buds? (Low Light/Heat/Overfeed)
Airy buds come from low PPFD, high heat, or too much N in bloom.
Larfy buds? Low light/heat/N issues—see causes and analyze fast.
Common Causes
- Insufficient light PPFD
- High temps reducing density
- Excess nitrogen in flower
- Poor airflow/humidity
How to Tell Which One You Have
Loose airy buds, long internodes; trichomes may be fine but structure light.
FAQ
Fix?
Increase PPFD within range, manage heat/RH, lower N in bloom.
Can late fix density?
Mostly set early/mid flower; improve for next run.
Defoliate?
Only to open light/air; don’t overdo.
