Eh, good point..
I probably should have given some description of what my intentions were. This is going to be something like 70% learning tool, 30% looks. This isn't an all out aquascape, as I don't yet have the ability to pull off the scaping process very well. I will however, be using this to learn a little about aquascaping if that makes sense. I look at it as setting myself up for a bit of failure now, with success in the long run.
Given my intentions, I'm basically after something like should stems have spacing between them, can they be directly next to each other, which of those situations is best for rosette plants, etc.
Biollante/CL_, you both make a good point, probably easier to ask this question with a list of plants and desired effect. Perhaps I'll come back to the question when I have a concrete list to provide. Left C, I'll have a look at that video tonight. Thanks guys.
