Weekly Kingdom

first off any amount over 750k is treated as the max amount in there so long as it stays above 750k, if you can afford to fill it all the way up go for it but it's really not needed as it wont take more than 75k out and 1% down a day (reset time is midnight gmt).

as far as what to gather the farming slot is mostly useless cause you'll get low lvl bush and hop seeds that are rarely used at all.

mahoganey and teak is ok however if your mainly after the nests and tree seeds from them your better off with the maples as it's 1 nest for every 100 maple logs, mahoganey and teak are close to 150 logs per nest.

herbs and flax whichever suits your needs more u'll get herb seeds every 100 herbs it gives u, i dont know the rate of herb seeds u get from the flax.

fish will give you some caskets and the odd clue scroll as a bonus. coal will give you gems a plenty.

personally it gathers full bar of herbs and the rest on maples for me and i top it off at 2m in the coffers whenever i check it
