Bat Guano: Yes or No? reading a grow guide from a seed company, they become apoplectic about guano, screaming: you'll never get it out of your soil! first, I'm assuming that they are talking about blending guano into the container (or ground). and, in general, after one grow, that soil is tossed, so why would/should I care that it stays in the soil? to date, I've NOT added guano to the soil; instead, I put it into an aerated tea, and damned little at that. somewhere I read that guano leaves a bad taste Rating: 5
