Hmmm. I think it should be fine. Make sure you clean the wood by baking, boiling, freezing, or a combination of 2 or more of these. Anyways, about the wood color. I use a variety of different colored wood and I'd say that dark wood can be great! In fact, I raise Dorcus brevis off of pretty dark substrate! Dark wood is usually more decayed, so it won't last as long, but it probably is a little healthier for many species. I personally like to mix different levels of decayed wood. Can you show me this substrate? What is it being used for?
