Recently I had a friend of mine over for a smoke session and we were talking about different things people do to improve the quality of their plants. It started with basic CO2 and fertilizer comments but then he told me something somewhat disturbing and I havent been able to get out of my head since. According to him, a friend of his who also grows uses his girlfriend's period as fertilizer for his plants claiming that the high content of minerals is very beneficial. Has anyone ever heard of this before or is this just some stoner BS? I don't think I would ever use this method even if it is beneficial but the mere suggestion has been nagging at me ever since I heard it. Any thoughts?
