Week 8 we are still flushing with tap water.
I had to remove some main cola's as there was rot. Decided to give it a few more days before harvest and stopped watering last day of week 8
@groen, get yourself a decent dehumidifier, they're starting around 45€
Or in terms of less space: dehumidifier pads from the HORNBACH of your choice
Besides that
For your next grow: ensure that theres not more than 53% humidity in your grow room, as well as good airflow. Therefore you wont get no budrot anymore.
