WOW awesome pictures - great looking plant! So is the purpose of the double potting that the net pot allows the roots to breath but the outside pot holds the moisture around the roots at the same time? Again beautiful plant!
Great results and well done on these roots! and very nice flowers too! Maybe something to consider... I have used the double pot also for many years. It for sure gives stunnng results in root growth. For me the challenge started when having to report and sometimes damaging a lot of the precious roots due to the small holes. This is why I abandoned this setup after a while. I now use a (inner) pot with larger circular holes ( I poked in with a round soldering iron ) which give far less damage when reportting.
