First timer.. IT also depends on how old your plant is.. During the seedling stage of a plant.. about 1-7 days after germiantion, a plant may need a little bit of water every 1-3 days.. becuase it does not have a very deep root structure, so it needs more frequent waterings
after 7 days of solid growth your plant should have developed a GOOD root system and will only need a thorough watering every 5-10 days.. depending on your room temperature and container size..
youn ever want your soil to be soggy and muddy.. except for a few hours after heavy watering..
cheers
