There are pistils, indicating a female plant, but I would be watching closely, bag seeds are nearly always the results of hermaphroditic females, meaning this trait is passed on to any seeds formed that way. By the lack of branching, it also looks very "male like", female plants usually develop branches quite early, but since it has pistils, the plant is female, but with a better than 50% chance of having male flowers or "bananas" at maturity. It would be safe to put in your tent, but observe it closely for any unusual growths. If you look at my diary "cannabis conundrums" and in week 7, you will find pictures of male flowers and hermaphroditic flowers, giving you a clue as to what to be on the lookout for.
Hope this helps,......... Organoman.
