well I guess you both can always grow it for the first time without hoping to get anything from it rather than the experience. you'll get the chance to see the several phases of the plant's development and learn to identify the parts of the process. keep buying your weed but use this as something that will help you in the future. just put the seeds there and don't create great expectations, focus only on watching and learning. find a place outdoors or indoors that is warm and gets enough light. this will do as a start - plus if you can live with this "weed growing purpose"
