I have one general question, but before I get into that, my first outdoor grow failed, so I was wondering if some soil attributes would play a part, like MiracleGrow...? ~Thanks to all that Write~
if you are going to use pots outdoors, I wouldn't recommend using MG soil, get some type of potting soil with perilite in it and no chemical nutes. Add your own nutes later. I've heard that excessive rain outdoors can release the nutes MG has too quickly, which can burn the plants.
