For my hybrids, I only water one kind per in-game day, because it basically ensures that there will be a new flower/s (depending on how many there are initially) there the next day. The more flowers you have, the more flowers they will produce.
I've got a ton more, including long list of QR code links, including turning regular images into QR codes and great guides for creating your own outfits. Also, massive number of website with premade outfits/paths etc from various sources.
I'd run out of space, fast. :/
