Thank you! I must say that my "setup" was to try and recreate SmileForAnts' in a minimalist-like approach that could be easily modified later.
Hydrostone (from Amazon because the store closes AT 5!!!) ~$20
Fish tank (walmart) ~$13
Tension rod (HomeDepot) ~$6
Play Sand (HomeDepot) ~$3
Fluon was the most expensive item simply because I WANTED A REALLY GOOD METHOD for keeping them in. When truthfully I don't think they've climbed on anything... oh well I've got enough until it breaks down. $35
Liquid feeder - would recommend skipping and doing it yourself. Don't be lazy like I was. $30
Epoxy was from work though it can't be more than $15 I'd imagine.
Magnets were laying around the house.
I've got fish tank...."plants" that never made it into the outworld. Besides the $60+whatever that went to byFormica because I'm lazy .... I spent ~$50 on resources. ~$120 total overall I'd say. *Rounding/estimating/guessing....
Plans for next year are to use more of the hydrostone but in a longer rectangle. I left a bare section on the base of the outworld where I'd like to put it. More importantly adult beverages won't be consumed during construction so I won't impatiently forget to sectionalize the hydration zone!
