Sitck on bathroom deodorizers aren't the sort of filter you'll need- a carbon filter such as an odor sok or a rigid model are correct for a grow of more than a plant or 2.

If your landlord knows, he can evict you because it's still FEDERALLY illegal in all states and the Feds can actually make a motion to seize property owned by someone who has knowledge of illegal activities on the premises.

Watering depends on your lights, soil type, size, and vigor of the plant.

And that's 'woman'

Happy harvestin.
