I got a whole bunch of composted horse manure from my step-dad. It is a few years old, so it is definitely dirt now. We had to take weeds off the top of the dirt, before shoveling into bags. My step dad said that I should bake it in the oven before using it indoors, in order to kill the bugs and weeds. This didn't sound right to me, my question is, what, if anything, do I need to prepare my dirt for an indoor grow?
