Just as a recommendation for your next grow, don't use roots organic, recycle your soil from this grow and add some amendments, but don't buy more roots organic. Most of the grows I've seen with it have issues with fungus gnats, not saying you will with this grow, but next grow you might not be as lucky. It's your choice in the end, just not sure if you were ever informed that it is common to have fungus gnats in roots organic soil.
