I use a mix of equal parts perlite, cow manure and peat moss. It won't burn your plants, but you will need to use nutrients, preferably ones that are water soluble.
i was thinking about starting my own outdoor, organic garden this summer, and for my soil i was thinking about mixing Foxfarm ocean forest with Miracle grow and perlite. Do any of you know if this would be safe for me to do? mixing foxfarm and MG.
