Choco Stables and gardening question

our fc has around 70 chocobo's in stable around 490 active members.... 3 gardens... we avg 144 plants per garden every 3 days. thats 432 pieces of food / 70 so you can potentially feed then 6 x per day with this much food ... but then this is if you do all 3 gardens in straight krakka root... what about cross breeding the plants and trying to figure out the rest of the seed recipes? ok so you use 2 of the 3 gardens for learning the recipes, making brooms to clean stables your down to1 garden again 144 pieces total so 2 pieces of food to feed aprox 70 chocobo per day at best :(. what we do is just feed the people's chcobo's 2 x a day for them free while we work the other 2 gardens for cross breeding while we also make brooms to keep stables at max cleanliness for our users.... but they should really make krakka root available from npcs!!!
