I also use a lot of Plantation Soil.
Have a bottom layer of hydro balls or a false bottom for the moisture to drain off too.
With many plants, the roots can be cut back, especially the Bromeliads, and then planted. If your looking to keep floor space, you sides can have a cork wall and then the bromeliad can be put into that with out any actual soil. It will eventually attach itself to the cork bark.
I don't think the snake plants have a very deep root, and the roots they do have can be spread out.
Biggest thing I have found with planting is the need for the plants to have something to keep them up or for the roots to grab on to such as some gravel or stones under or around the plant. I do this with larger plants so they can attach themselves to something for support. I have also put larger stones (rocks)or pieces of driftwood in places to support things at angles.
