We offer both the organic and regular fertilizer. I haven't had too many customers even ask about the organics. I have a lot of haz-mat training and access to special haz-mat net work. After looking over some of the LD levels of things in my house I think I am more worried about those chemicals than the fert on the lawns. For those trying to save the environment they should stop showing up at the customers house and driving gas powered vehicles. The MSDS on gas would blow you away. Just some thoughts.
