I'm setting up a small tube run from the nest to a 2nd larger outworld.
I don't have the ants on hand yet (Pogonomyrmex Occidentalis) as i've been setting up to be ready for them before they arrive. Which is likely later this week if they ship today(weather decides).
What i'm unsure of is tube sizing to use for this. Currently i've set it up with tube that fits the 3/8 sized ports on the mini hearth and outworld. But I considered that if the ants were foraging the 3/8 tube run(about 18" long) might be a little small for two way traffic and seed carrying. But i also considered the possibility that if i use too large a tubing they might decide to move into the tube.
So any advice on this setup? Would you use smaller or larger tubing for such run to an outworld?
Thanks for your time and efforts,
