Thats true for an Indica plant, but why grow it cold when you can shoot for good yield and quality. Take pride in your grow when you can, if you can't put heaters down in your basement because of saftey issues, thats ok, get some blankets, staple gun, or something that will cling the blankets in place and leave yourself an access area to work on them. Try to keep them warm, ALWAYS.
