Don't jump on me, I'm not disagreeing with the world CO2 problem, but just an fyi (I'm a teacher), CO2 rise at night is also a natural phenomenon. All plants give off CO2 when there is no photosynthesis. I keep a planted fish tank which I supplement with a small CO2 reactor (baking soda & citric acid). It must be turned off at night so the fish won't suffocate from too much CO2 when the plants give it off when the lights are off.
I agree, a fall pad is the most important component for any kind of climbing wall! But it will be the most expensive item on the supply list. A 4'x8' 2in thick pad starts around $150.
Wow! A real labor of love! Impressive job!
