What is this foul looking stuff?!? It's a special tonic I learned about on another site. It's actually a culture of bacteria...namely Lacto Bacillus:hubba:. Now that stuff on the top is no good for my plants but your pets love it and it's very healthy for them. This is what you are left with... Concentrated Lacto Bacteria. Don't worry, it doesn't smell at any time during making the culture. L Bacillus takes care of foul odors. Dilute the culture by 20 with a some fresh water. Thats something like 6 or 7 teaspoons a gallon. PH balance the water and give your ladies a drink:hubba:!
