Water thoroughly. I water till there is run off out of the pot, wait a few minutes and do it again. Then let your soil dry. Ideally, you will water again just before the plants show that they need watering again. Just check them daily (if possible) and water when the soil has had a chance to dry.
i can check the plants every 4-5 hours if i need to. so i should re water them if they get to dry as much as i can?
I wouldn't think they will dry out that quickly. check them once a day and you should be fine. What sort of planting medium/soil are you using?
