When I build a stand for an aquarium, I usually construct it out of wood. In a greenhouse however, it would seem to me that wood is a bad choice to build stands. I am worried about the humidity rotting it out and causing a collapse of some sort. What are your thoughts on the use of wood for stand construction in a greenhouse aquaculture facility? The stands I am thinking about must be able to support 300 gallon Rubbermaid containers. If wood is not a good material, are there plastic products that can be used as stands? Thanks.
