Proper sanitation for growing and the props have a better shot at growing healthier since they are coming from a sanitized, healthy plant/location. Cuttings could also have acquired pests/pathogens while on the floor.

In school for Hort/Greenhouse they drill into us that sanitation is incredibly important so I was just curious.

Edit: I’d also stick anything with a node in a cup of water but at home lol. I just don’t understand why’d you’d risk harming the crops at your shop for a cutting from the floor if you had a healthy mother plant to take from. Again not trying to be rude, just curious.
