first.. fig cuttings don't need rooting hormone. it will definitely root faster with one, but there are some reports that hormone might not help in long run. didn't follow the full story, but test shows that top growth is slow with hormone than ones without.
you can store the cuttings, or you can start rooting them. i don't store the cuttings, for me fresh cuttings root better than old cuttings. there are many methods initiating the roots. once root is there, you move to cup or small pot. once night temp is above 50, you leave them outside.
