Week 25, and it is a photo finish.
I was able to flush for 12 days, just under 2 weeks. Close enough for me.
It has been raining and 90% RH almost every day. I had to pull the plug on 3 out of 4 plants. So on Oct 4th, day 189, I have 3 plants hanging in the garage.
I am using a dehumidifier to keep the RH at around 55%, with several fans for airflow. I am aiming for a 7 to 10 day dry, but it is a little warm in the garage (22'F or 72'F).
The 4th plant (the runt) is still not ready. It is about a week behind the other plants, but the buds look fat and frosty.
This is the home stretch, the last 6 months have all come down to this next week.
Saying a prayer to the Canna Gods.
