Chinese Wisteria Bonsai II

I noticed yesterday evening that two of my Wisteria seeds have germinated. Yay!!! The expected germination time was said to be 21 days. However, it has only been 10 days. I guess these guys were a little more eager than their buddies. Today I put them outside for just 20 minutes to receive a little sunshine. I want to be careful that I don't allow the seedlings to dry out as they are still fragile in this early stage, but I know that as trees, they will require full, direct sunlight. So I want to begin conditioning them for such. I watered them well before I set them out. Germination rate is 20%.
