Hi received my first Utric a few weeks back from Jeff_Forever (Thanks Jeff!!) and I thought I'd share what I've done with it.
I got this idea from the Savage Garden, hopefully this works just as well.
I used an empty plastic container (pistachio container -- I like them to Bella lol) and cut out the top to fit the pot. Hopefully from what I saw online and in the book the traps will go through the holes in the bottom of the pot and be viewable through the plastic. I added a few drops of H2O2 to prevent algal growth as well. If i'm correct i'm seeing flower stalks come up already so I'll post some pics soon as well! Thanks for looking!
