Thanks for all the great input guys! I thought it might be normal.
Ruuting, yes, they have practically doubled. I was shocked. When I left the buds were just breaking. Gone 5 days and I had 6 to 8 inches of new growth each with new big leaves everywhere. Roots coming out of the bottom holes as well.
Rewton, I was thinking the same. I haven't left them in the sun after seeing that to see for sure, but I suspect while I was gone and wasn't here to move them, they were probably wilting during the day and recovering at night like you said.
I've been watering about once a week. I know that doesn't seem like a lot, but even after 5 or 6 days the pots still feel very heavy with water.
