This neoprene collar is a pliable circular sponge, with a slit from the edge to the center that allows it to perfectly fit the plant's stem and firmly keep the base attached to the mesh pots used in aeroponics systems like propergator, rainforest, etc.
The collar acts as a seal, preventing light from entering and protecting the roots against the attack of pathogens leading to fungal attacks or other diseases.
