I use two 5 gal. pots to grow. Those two pots w/ FF soil in them were sitting for about 4 months. Actually one pot was sitting for about 6 months because the plant that in that one had been male and pulled. The other produced a nice Skunk female. After it finished, I mixed in some more perlite, more dolomite lime , and some bone meal but decided on trying to reuse the FF ocean forest again and let the pots sit for awhile. But when I watered for the first time for another grow, before I put seedlings in, the soil put out this strong, sweetish, acrid mildew smell. I was thinking I should douse the pots with some hydrogen peroxide, or should I just scrap this soil and mix up some more fresh FF, dolomite, bone meal, and perlite?
