I just made some changes..have removed the metal pinwheel, covered the metal tube opening with this red cap, added a smaller clay container and have put one of my Semp 'Kalinda' and have added a Sedum rubrotinctum cutting on the middle containers..so fingers crossed..hope the plants make it.
Sempervivum 'Kalinda'
Sedum rubrotinctum and Crassula alpestris
Oscularia caulescens and a noid succulent
The whole set-up for now:
Still open for suggestions in case my set-up goes haywire.
