I'm wondering what kind of bulb I should use to grow a single cannabis plant in an enclosed location(closet). there is enough openings in the closet to give the plant ventilation and i intend to move it outside during night so that it has sufficient co2. i want the cheapest bulb, but it should still be effective. i'm not interested in spending a lot of money to grow a single plant one time - this is a project, not a harvest by any means. so please, i've looked everywhere and haven't been able to find anything helpful. i know there are different kinds of lights such as metal halide and low pressure sodium, etc. but what are the required lumens and kelvin for cannabis to grow?
