How much water does a 9 inch marijuana plant need?

Answer 1

Truth is not much. i usually tend to spritz with water once a day [moring and late afternoon] Cannabis Sativa tends to over water easy.But 1 cup of water how ever much you think will be enough to reach the roots at the baootom like i said spritz it daily with water once it starts budding reduce this spray only leaves and stems too much water on the buds will make them mold so look at the weather channel more once tht happens cuz u dont want moldy grass!
