I talked to Aj Calisi at the Tampa show about greenhouses, he has several setup for frogs that do better with large enclosure, and he built one for about $500. He built it out of wood, and then sealed it with a marine epoxy call Gluvit. He has had water and soil samples taken and they have been clear of any harmful chemicals. It has been set up for three years. It is then screened in with heavy duty shade cloth. I asked him about temperature, and he thought that would be a problem from what everybody had told him, and with heavy planting, the shade cloth, and waterfalls the temperature is in acceptable levels. My point is that if you live in a tropical climate a greenhouse for frogs is fairly inexpensive to build.
