I usually use many of the available public farms but we wanted to see about linking a few public farms with our HUB workshop. Parent planet is Imdaari so wanted to see if anyone has any public farms there. 
As the oldest resident of Imdaari, the only public farms that I know of on Imdaari, is the now defunct gleam farm by code gleam, which can be accessed from my portal hub on Imdaari,
the gleam farm made by portal seekers,
and the clay/gleam farm by Diablo
