I feel really dumb for asking such a thing but I am missing the whole point of the peka glade.

OK, it opens twice a day... but which hours? is it random? and, what's with the pitchers/jars and such? sorry if I missed some post or something but I swear I looked for it.

The Peka Glade is for getting the Glade Pets. If I remember right it's open 8-9am and 8-9pm. You have to get the Ornate Floral Pitcher to get water for it, and it turns it into a glade potion for your pet.

None of the other jars/pitchers work, just the one. (:
