When I got my plants a week and a half ago, I placed them in the aquarium in a manner to help them get nutrients, light, etc to help them start roots. Most of them are stem plants and didn't have much in the way of roots when I got them.
As of today, most of the stem plants have at least 3" roots growing above the substrate, enough that I could make new plants from them if I so desired (not yet though). Just about everything is sprouting new leaves that look nice and healthy.
The slowest growing is the Rotala macranda which most have little nodes where the roots would come out. Some have short roots that have made it into the substrate.
I know these are known for being difficult to get established, so it looks like things are going well.
So the plants are not where I want them to be. I wondered, how long do you think I should wait, or what signs do I look for before moving them to their permanent spots?
