This Aquarium Vine Trainer / Shelf can be used to organise above aquarium plants such as Devils Ivy. There are two end peices that hang on 8mm thick glass and hold a DN 15mm PVC pipe (Class 18). I used 1m PVC - longer pipes may flex. Simply zip tie the vine afterwards.
 

Originally designed for the Aquarium one ‘Imaginarium’ tank which is approx 100x40x45cm with 8mm glass. This can be used on any 8mm thick glass, length depends on PVC pipe length.

Supports not required, no special settings needed, 0.2mm hight works well
