Scientifically minded people-if you have a tube that is 27 in long by 9 in in diameter, how many gal is that? I have a glass tube that was made by Smith and Hawkin for putting over plants to increase humidity. This shape is extremely appealing to me and wondered how to calculate the size to see if some modification to it would render it to be a big enough/nice enough home for my Imitators. If its too small or too unstable or something, I will have a Hex made to these dimentions: 30 in high x 16 in diameter. What would the gal be on that? And if you were to have it custom made, would you put a front or side door on it and what would you specify?
