Feeder Adapter for Polys

I am heading off again. This time for 3 weeks. I placed my feeder adapter on that allows me to feed both patties and syrup.
The challenge with most poly equipment are the very tight tolerances. I am unable to feed patties at the same time as liquid syrup using the standard gear. I insulated and drilled out an inner cover to allow me to do both.
I will check mid-week to see if I need to add any extra space to mitigate swarming while I am gone. It is still cold now with not much for forage yet other than some early willow and the odd crocus. My goal will be to pump in about 10L of 1:1.3 (sugar:water) per colony (22lbs) which should simulate a nectar flow and boost up the brooding.
