Yes i did a forum search and can only find info on using the light diffuser panels. But i see in pictures elsewhere people using a black grate with larger square or diamond shaped holes. Its thicker too. Where can i find this type of grate? I want a better method of setting up my boxes to cut down chamber of collapse or possible mold. The pictures Ive seen of this particular grate with eggs on top looks more affective. The eggs are always full round and white up until hatch time too. Any help is appreciated! Thanks! ~Monica
