Re: dis-mounting orchids
Mine I couldn't twist because their roots were weaving inside the crevices of the pressed cork, though I suppose the cedar-slab ones could have been removed this way. I'm pretty sure I did do a cleansing of the roots while bare-root too, since I'm used to removing dead roots any time I unpot an orchid. (I find it quite therapeutic, actually, like weeding outside!)
I did see your superglue mount video at some point months ago, and it's something I intend to try in a future build or as I put more plants into this one. I think they recommend this type of adhesive for Tillandsia mounting too, which is another pet project (for who-knows-when). Looks like Gorilla Glue in the vid?
