Your supple pot plant needs love and attention. It also needs light. If you're growing a small plant for strictly personal use, there's no need for an elaborate operation with indoor specialty lights. The sun will do. The sun's the best anyway.
However, be sure that your neighbors can't look through your window and see your beautiful horticulture. From the Lakewood police blotter:
DANGEROUS DRUGS, BAXTERLY AVENUE: A man’s green thumb got him into trouble June 22. Police got a tip that there was marijuana growing in a planting pot placed near a window at his residence. Police investigated and found four marijuana plants growing in the pot, along with a pipe. The man was cited for illegal cultivation and possession of drug paraphernalia.
