good questions kid it was a tough decision but the old tent lasted 4 years or so and it still will work but light will get in do to open sippers ,A new tent is $260 the materials for the new room will run about $360 I have a door and insulation(thats why I have so much shit never throw it out). its nice in the cellar stays about 70s in winter and high 70s in summer but I'm insulating the walls to keep the brick from wicking cold in ,and hopefully maintain a more even temp for the girls
