Its the end of week 3 and the forth node is just coming through, I think I might top her towards the end of next week. Roots are starting to show through the bottom of the air pot and there are no signs of any deficiencies. I haven't changed anything to the feeding schedule and iv only needed to water once this week. Really happy with the progress so far! I also decided to add a carbon filter to the space bucket to help with any smells in the future, its made from a plastic food Container filled with activated carbon, I still want to get another fan to help pull air through it.
