Watering Before Sleep

After choosing a pot and seeds, watering them before sleep in the initial state made them bloom in about 2 hours. When the flowers aren't bloomed, you get 3 coins and 3 fairies each. The points from 3 fairies are roughly 60-90 points after watching 20-30 ads and multiplying by 3, so I don't think it's necessary to make them bloom while sleeping. Also, if you're going to wake up and do things to make them bloom, it's hard to log back in right away, so honestly, I think it's fine to just water them before bed and go to sleep.
