how long do you have to water

[Mike C]

hello.i have a question for you. I was just wondering how long do you have to have your water going for in a cycle?

You just need to water long enough to wet the roots and medium every 20 minutes. If you have a 15 minute timer then water 15 minutes on 30 minutes off 15 minutes on and so on. If you use a 30 minute timer then water 30 minutes on 30 off and so on.
