General tips on changing parameters:
Since the plant responds right away to each parameter change you make (regrowing if necessary), you can play with parameters even if you don't understand what they do. Just remember you can undo your changes.
Remember that the plant won't respond until you let up the mouse button when you are using a slider.
You can divide parameters into two large groups: parameters that only change drawing (like colors and sizes) and parameters that change growth (like days and biomass percentages). In each parameter section, changing the parameters in the groups labeled "Drawing" and "Size" is much easier to understand than changing the parameter in the "Creation and growth" or "Timing" groups. Start with the drawing parameters first.
If you change a parameter and the plant doesn't seem to change, this is often because the expression of the parameter depends on another parameter. For example, if you reduce the biomass required to make a leaf (

).
If there is a parameter you are having a hard time with, open one of the libraries of plants that came with PlantStudio and look at the parameter you are trying to understand on each plant, one at a time. From the differences you may be able to see what the parameter does.
