I bought some Miracle Grow Performance because it is organic and does not have time released nitrogen. I thought I would try it since I can get it easily, but it was infested with fungus gnats. I ended up throwing it outside. I put a couple of mature seedlings in it and they didn't grow at all in two weeks. I am thankful I didn't have larger plants in it. I know there are treatments but since the plants were so small that was the best thing I could think of to do.
