Besides you can not hide a grow from mom! She will either hear the hum of the ballasts, feel the heat off of the lights or smell the foilage after a month of growing. There's just no way! And even if you do get them into flowering, unless you are using the proper lights all you'll end up with are long stringy and useless leaves on a stick. Windowsills, incandescent lights, uv/blacklights will not work! You need flourescents at the very least and HID's for the best results. Anything thing else is a waste of time.
