Don't take risk.Last 3 times Ino flowers was around,I get 30 flowers from free stamina daily+hot springs.That's more or less 500 stamina per day,3500 for all 7 days.Which make 1 flower per 117 stamina.Let say I'm lucky,and we can round it up to,maybe 150 stamina per flower.So you need at least 38 000 stamina,that's 760 normal potions,or 3 800 small ones.
