Monster realms are created by an area being filled beyond a certain level with monster mana (and it takes a lot and is usually built up over a long period of time), so yes to make one of substantial size on one's own in a matter of minutes does require an immense amount of power.

As for the above idea of planting prisoner fruits and other such things to create such a realm, that would be a difficult way to do it. Monster realm plants feed on monster mana, they don't seem to produce it themselves (though they can store it), so you would have to provide it somehow for them to grow in the first place. And because the plants don't seem to produce the energy that causes the change to a monster realm, the plants alone would not be able to change a realm (rather it would be the people they transform that change the realm).
