Hi Jack,
Wow! Ingenious photography. I notice those Haageana leaves are nice and slim, instead of wide. This is a pic of a couple of zinnias that I will be re-potting to 5-inch square pots soon. This picture taken today.
You can see their roots crowding the walls of the "clear" 3.25-inch square orchid pots. You have to click on the photo to see the large version to see those root details. This tall photo works much better here than it did over at GardenWeb.
