Hi, I am about to make an incubator, and I have a plastic sheet. Yesterday I cut them and made a box shape so far. But someone told me that it should NOT be all plastic, as because of the high humidity, water gets down on the floor all the time and raises the humidity, so it would be difficult to control it. I am about to put the lights and the vent today, once I will be sure that all plastic could do the job. Here is the photo of my will be incubator. http://imageshack.us/photo/my-images/707/incubator.jpg/ Please advice. Thanks a lot. Moulie.
