On plastic foundation/frames: Count me as one of those who has had good success with plastic foundation/frames. My observation has been that if the nectar flow is good, the bees will draw anything. If the nectar flow is not good, everything will be ignored. Pluses for plastic: Easy to install (no installation in the case of all plastic frames) Tolerant of abuse. Can be installed in frames on a winter day if you like. Bees won't chew holes in undrawn foundation No extracter "blowouts" If the comb is eaten by wax moths, just put the sheet back in the hive during the next honeflow for re-use Disadvantages: Plastic foundation costs a bit more No good for comb honey production IMHO, except for comb honey production, plastic foundation is so superior to everything else that it makes other types of foundation obsolete.
