It does not matter when you water the plant, it's just how often you watered it in three days, and you have to water each plant at least once in three days. Makes 3 ways to water a plant, namely once, twice, and three times. And yes, watering the plant first day and then no more is the same as watering the plant only the last day, or whatever combination you find.
It does matter when you fertilize a plant. So, there are 8 possible combinations of how to fertilize a plant, and I can write them down for you:
---, f--, -f-, --f, -ff, f-f, ff-, fff (where f stands for fertilize the plant, and - for not; the first place stands for the first day, the second for the second, the third for the third.)
3 ways to water x 8 ways to fertilize = 24 possible combinations of watering / fertilizing, hence 24 items.
Thank you!
I should have read it more carefully. *hits head*
