What he's saying is that in his experience it's uncommon for the plants to need water every day/ every other day.I dont mean to bust your balls but I'm not really sure what you mean by "feels like". Either they do or they dont need water every other day. So are they drying out over that time? Then it feels like they need that much because that is how much they need. If its not drying out then the feeling is just you and as to why...thats not a answer a forum can give.
