This is a photo of a Feed Rim that I am currently assembling to feed Pollen Substitute.
Locally, our annual rainfall was 50% of the 12.5" average.
I will post some additional photos and videos to show the use of Feed Rims.

The feed Rims are made out of 15/32" OSB and stapled together with 3/8" crown X 7/8" SENCO galvanized staples.
They will be hot dipped in paraffin after they have been in the sun for a few days.
