I imagine a LOT of our fine young growers are going "EEEEWWWW!!!! Gross!!!" But there is, in reality, little difference in using dried blood meal or menstrual blood as a fertilizer, providing your GF is healthy. Considering "mad cow disease" and all the hormones, antibiotics and stuff they feed cows and pigs nowadays, it might even be safer! I'd mix it with water for ease of handling and use it just like I would blood meal. - Granny:hippy:
Storm Crow Reviewed by Storm Crow on . Menstrual Blood as fertilizer? My wife has been using a diva cup instead of tampons or pads, and suggested using it as a fertilizer. Has anyone done this before? Results? And as far as application, should it be dilluted and applied during a regular watering? Is there a time when it's application would be of most benefit (veg/flower/on her once a month schedule)? Rating: 5
