Where do you plan to get the guano?

I've decided stay with tomato tone and dr earth. I do use guano high phosphorus for budding. Cheapest at home depot.

Many of us organic growers determined a long time ago that using bat guano helped support the exploitation of the people that collected it (paid very low wages) and exposed them to health problems they should not be exposed to, so we do not use bat guano. It is also quite expensive when compared to other nutrient sources. Using bat guano could also expose you to histoplasmosis.

Glad to read that you decided to use something else.

I think those people being paid low wages are probably happy to be able to put food on their table. Horrors upon horrors I also use peat moss and perlite with all the dust swirling about. BTW, I clearly stated that I use high P guano and will buy another bag when needed.
