Ok so it looks like several of the items used in chocobo raising take gardening to make. Now this would be ok if there was personal housing and each person could have their own garden. As it is now only like FC leaders can have gardens, although they can give other people access, if you want to grow your own stuff are not a leader of a FC you are out of luck most of the time.

Because of this stuff like glazenuts which are used for crafting certain pets and furnishings are like 500k-1m.

Now then the limit break item for chocobos Thavnairian Onion is needed every level past 10. Now then with only a select few FC owners being able to grow these and needing 10 of them to max your chocobo the prices will most likely be insane 1m each probably.

The thing is prices on all garden items will stay crazy high until personal housing comes out and with a major part of chocobo raising taking gardening it will be unaffordable for most of the playerbase.
