I filled out a chart for the flower farms to see how many flowers you would need to last you through the event. The chart is for just one farm, and assumes a 10 second travel time (35 min, 40 seconds total cycle). So basically, on any given day, if you reach this quantity of flowers in your farm, you're good through the end of the event, and can focus on helping out guildmates. Also notable, by the start of the deactivation week, you'll need in the ballpark of 250-280 flowers in each farm to get you to the very end. Not sure if this will be relevant for anyone, but since I made it for my own reference I thought I would share. (Hopefully I didn't make an error. Was never really great at math.) (Also, sorry for the poor formatting.)
