I bought the 10" and kept it in the dappled fairly bright light under my apple tree about 1 1/2 mos during summer; it grew a good 6" + and have now brought it in for the winter. It is tolerating the change well to moderate indirect light (so far, so good, 2 weeks) and cooler fall indoor temps. We also had to go up 2 pot sizes in this time. Very, very pleased, hope it continues to do well.
