Have a look up in the Articles section and take a read. Growing in soil in veg usually requires watering when dry. So if you're growing in 3 or 5 gallon pots maybe every 2 to 3 days, but then it depends if you're growing organic which requires to always be moist. That will all depend on your environmental control too. Humidty, temperature, lights being used and airflow. What size space are you planning on growing?
