Starting at the old master cannoli statue in the secret woods, you'll want to bring a sweet gem berry which takes a full season to grow from rare seeds, but the permanent energy boost from the stardrop is worth the wait. The real money-maker setup starts with getting that statue of perfection from grandpa's shrine, timing it right after you hit 4 candles, since it'll give you 2-8 iridium ore every single morning which is perfect for crafting those quality sprinklers.

For maximum profit you're gonna want to time your starfruit plantings carefully - buy seeds from sandy at the oasis for 400g each and plant them as soon as summer hits. The 13-day growth cycle means you can squeeze in three harvests if you're using speed-gro and picked the agriculturist profession, just watch your timing with the seasonal transition. While they're growing, process previous harvests into wine which takes 7 days in kegs, then age in casks for another 2 seasons to hit that sweet iridium quality price of 4,500g per bottle.

Maybe interesting - if you've got a million gold lying around, grab the statue of endless fortune from the casino since it'll give you birthday-themed gifts and sometimes valuable items that can help fund more starfruit operations. Just remember that maximizing profits means having enough kegs and casks ready before your harvests come in, so plan your cellar space accordingly.
