BUT I am trying not to buy from Amazon and support small businesses. The company that produces the kit is from UTAH. free shipping over $29.

Now do I need an injector of some sort to add it into the soil, or can I just pour like I do other liquid ferts. Are injectors simply for those using hydroponics? Sorry if that is a stupid question!
