I have many peanuts from last Andy's parcel. I'm thinking of using them as filling material to transfer my vanda into mixed with around 30% sphagmoss. I assume these peanut will be way alot more airier than any other medium, making the Vanda believe that it is not being buried and weighted down. Anything to help me do less of a chore with these orchid.
I personally love the inert white packing peanuts for the areas of the pot that don't have live roots. Hopefully that means fewer "empty areas" at time of next repotting. That being said, if I bought a plant with a ton of peanuts used in this fashion I might be less than thrilled - I expect better roots from my vendors!
