Parallel Camponotus Project

[J1nx88]

So, for my first attempt at settling up an ant colony I have decided that I will be doing 2 Camponotus spp in parallel.
1) I got in contact with my local GAN and have arranged to get 2 Camponotus spp (Maculatus and Cosmicus). 1 queen and a few nanitics.
2) I have ordered 2 Camponotus hybrid nests 2.0 from AntsCanada... Plus lots of tubing
3) I want to create my own outworlds for them (in time). Starting small and eventually expanding.
What kind of variables would interesting to vary between these 2 spp?
The hybrid nest will be kept in the same conditions - same room, same humidity etc. but what change in variables in the outworlds will be most interesting?
A carb-rich diet vs a protein-rich diet?
Keeping 1 colony in a small environment while the other has an expansive environment?
Using different substrates? Sawdust vs potting soil?
Live plants vs fake plants?
Ideas?

You could also try with live or dead food and lighting intensity or how often you check on them if it makes a difference in speed of growth
