depending on the soil drainage, and retention, you will need to water (if planted in the ground itself) about every 4 to 10 days. you dont want to drownd them, but you want moisture to help them feed. and letting them get a little dry for a day or so between watering helps the roots spread out to find other water sources. there is no prefect number for every grow, and plant. it is all about soil/climate/ and humidity. just go for it. and start with a 3 day water cycle, then add a day or so, until they day comes where you soo the leafs droop a bit, cuz it got a little to dry, then back up 1 day on the trips. if it got dry on day 10, go back to every 8 or 9 days.
