Hi everybody. This is Simon's 20gal L tank. The top is modified w/ duct tape and foil (thanks to the sticky on this forum! ) I've got two small pieces of plexiglass over the openings that I use for adjusting the humidity. It works great. Simon had a great shed last week; I got the humidity up to 71% w/o any problems. The sides and back are covered w/ contact paper and I added a 1 1/2 inch strip to the front. Funny because he likes to peek over, then duck behind it. Thanks for checkin' it out!
