Terpines/ light strength
sanibelislstarted grow question 6h ago
Two days ago my Mulberry autoflower had my whole house stinking to high heaven. I turned up her lights(NextLight Mega Pro 640 watt)from 50 percent to 75(650 PPFD to 950… 45 DLI to 65) and the smell has almost disappeared. Why? The flowers seem to like the extra power.

The smell very well could've been from the terpenes burning off.
Vpd will also dictate terpene preservation.
If you're smelling your plants really strongly, it could be a bad thing.
Check your vpd and possibly what kpa certain terpenes burn off at.
My main recommendation is keep vpd lower
