Jstall, # 14 and # 17 that are pictured a few post before this one are my most prolific growers as of now. It's funny how some put on leaves and no roots and others started with the roots and no leaves. The mystery of figs. Also remember it's only been 3 weeks since I took them out of the fridge.
As far as adding water, I don't plan to unless the moisture in the cup drops to a reading of 2 on my meter and then it will only be a few drops at the time. The roots seen in the pictures are not yet able to absorb water. They need to branch out with feeder roots before they can take up water. When my roots start branching out and I have a nice root ball and leaves are looking healthy, I'll pot them directly into 1 gallon pots with some MG potting soil without moisture crystals or fertilizer. At that point I will start to water but only sparingly to keep the moisture on my meter about 4 - 6.
Remember they are in a sealed environment in the greenhouse and moisture should remain nearly constant. Moisture does travel out of the cup when I open it for a while and the reading on my meter drops, but after being closed again, the moisture level returns back to where it was. Any lost moisture is replace with moisture from the newspaper in the bottom of the greenhouse. Its quite remarkable how it works. I was a little skeptical when it was explained to me, but let me tell you, it does work.
Now if I can get some mature trees out of this, it will be great. If not, well then back to the drawing board.
