Abby if you are interested in a small container, I know I have seen it in a quart size at my local Fred Meyer. Don't know if you have one in Arizona. Wal-Mart has a good garden supply too.
I had a few friends ask because they had transplanted some phals and they became very limp-y. I will tell them about smaller sizes. I have put a hold on transplanting right now because school is about to start up again. thanks for the tip quiltingwacko. i will be sure to pass it on to my friends.
