Moon Cactus on Opuntia(Questions)

[coltonschultz]

Hello all,
Recently I took one of the offsets my moon cactus(grafted on hylocereus) was producing and grafted it onto what I think is Opuntia ficus indica(Obviously some sort of Opuntia). I used some super glue and rubber banded the graft down until I thought it held. Here are some pictures:

So, I have a few questions.
What kind of light should I give this plant?
Do I need to keep pressure on with the rubber bands for longer to ensure the graft takes? (I had the rubber bands on for a day and used super glue)
Has anyone had success grafting on opuntia, and does anyone know the compatibility of these two?
Thanks!

All cacti are compatible, however you should have left it with the rubber bands longer. I wait a week minimum before removing the bandages. Important grafts get two weeks undisturbed. Changing the pressure before they knit is asking for a failed graft.

Thank you! Fortunately I have tons of pups growing from my moon cactus, so if this one fails, I can always try again! Maybe the super glue combined with the pressure I had on will make the graft take, but we shall find out!

The scion is big enough you could try again with it if it doesn't take. It can probably survive a year without roots if it isn't in the sun.
