You usually don't have space for 50 dragons of one element in ur park, so, u can grow ur dragons to level 10, then put them in the hibernation cave whilst u hatch new dragons to fill ur exhibits, level them up to 10. Until u have 50 level 10 dragons. The way it saves gold is that once you've done this u'll want to level all of those dragons up to 15, without the cave you'd have sold almost 50 level 10 dragons to make space for new ones as they came thru and had to start over from level 1 dragons. (which is exactly what I did- stupid of me Hugh)
