i just got those shipped to me from Thailand
i have only 2 grafts and not complete but i was told to cut leaves from the piece your grafting on and takes 5-7 weeks. This is one reason some like plastic they can see the graft and some rubber bands you can for sure to see.
then I custom order grafted 90 days to shipment from Thailand saw 30 to pick out all the root stock and grafting pieces Then they graft and leave for 60 days before they trust to ship. just fyi
the rack is a METRO shelf cam get at lowes or home depot mine $60.00 ish
