Late flower humidity targets before the rain hits

If you're pushing into week 6-7 of flower outdoors and you live anywhere with fall moisture, this is the window where you lose a crop. Botrytis doesn't need much. Once nights drop into the 50s and morning fog starts rolling in, your dense colas are basically a petri dish waiting to happen. The number i watch hardest is the overnight low RH. You want to stay under 55% if possible. Above 65% for multiple nights in a row is where i start seeing grey fuzz in the inner bud sites, usually hidden until it's already spreading. A cheap wireless sensor hung right in the canopy tells you more than any weather app. Anyways, the intervention i've found most useful at this stage is aggressive lollipopping of anything below the top third of the plant at week 5. Better airflow through the lower canopy buys you days. Literal days matter when you're watching a 10-day rain forecast in October. If you can cover your plants at night with a clear poly tarp pitched so condensation runs off, do it. Vent the ends, don't let it sit sealed. You're trying to keep that surface moisture off the flowers, not cook them. This alone saved a Zkittlez run i had two seasons ago when we got two straight weeks of drizzle in late September. Harvest a few days early before a multi-day rain event if you're already at good trichome development. Slightly early beats total loss every time.

I actually saved a The Seed Pharm Zkittlez run two seasons ago doing something similar when we got hit with back to back rain. Harvested a few days early and it paid off.
