This is the wrong place for your question...

Medical Marijuana Methods: Methods of using cannabis. Techniques, joints, bongs, pipes, papers, vaporizers.

But depends on the strain, plant's age and type of medium/system (soil/hydro). I'd post in the hydroponics (if you are using hydro) section with as much detailed information as possible.
