I'm looking for nice clear plans for a bottom mounted (not front)pollen trap that would work for commecial setup. Rear collection drawer prefered. So let me know what type you think is good? I like the sundance traps but are expensive. Looking for a trap similar to a modified OAC trap. I have acess to all types of hardware cloth from #5 mesh to #8. Would mostly like plans for a good working design. Also what you think one of those good designs are?
