It's way too early to predict an Oct. 5 harvest date!
Most folks use 62% packs so that's a good guideline, and how long the buds dry before burping will completely depend on the RH where they're drying. You want to jar them when the buds are around 70% so you can burp them down to 62% over two weeks or so, before sealing them up for the cure.
An alternative to jars for large harvests are turkey roasting bags in sealed buckets, like from Home Depot or Lowe's. I burp in the turkey bags but still cure in jars, but buckets work well for large quantities if they're closed tight.
@Morda Grown I've had major aphid infestations in flower without rot, so I'm thinking there was a different cause for yours. My rot was either caterpillars or dense buds/high humidity/bad luck.
