I'm glad it's working for you. I don't remember who first suggested it, but I read about it on the forum and gave it a try, with good results. Four of my potted figs are in water trays pretty much all the time: two are recently-rooted cuttings, and the others are up around the 3-gallon size.
I'm only doing it with pots that are tall enough that the upper soil doesn't get saturated, and all appear to be thriving. But, since many people seem to have problems when the soil is wet, be cautious with this approach. I think it helps that I'm in an area that is hot and dry, and it also probably makes a difference that these figs are all getting full sun much of the day (the bigger two don't get any shade at all, except first thing in the morning).
