Well, on another note, "when something is too good to be true it probably is".
I bought a flat of bridgesii cuts from him in my novice days, for a reasonable $55 or so.
I was so happy when they arrived, 6-7 big cuts of bridgesii. Upon unwrapping them I noticed (as he put it) "small signs of black rot" were actually huge spots of fungal or bacterial infection that somehow all managed to be on the backside during the photographing of the cuttings. There were huge black rings all over the cuttings.
It get's worse. After about 2 weeks I started noticing serious scarring on all the tips. I got out a magnifying glass and sure enough, RED SPIDER MITES. It was too late, they spread to most of my rooting cacti and took weeks of thorough care to eradicate.
BUYING FROM VERNE WAS AN ABSOLUTE DISASTER! AVOID LIKE THE PLAGuE BECAUSE IT WILL PLAGUE YOUR OTHER CACTI!
