I plan on using a 11 hr photoperiod. What is the best bulb to use? Should i leave the light on during the day or at night?

I also have plans to have a waterfall in the tank. Is this a good idea or bad? I would have a gravity top off to make sure it does not dry out. Would the waterfall increase humidity? And would it also help the humidity to add a fogger? If not, could i use it for visual effects?

What is the best substrate to use? I read that newspaper is good for juveniles and cypress mulch would suffice for adults. What is the best to go with, cleaning is no problem, i want the best for my new addition. As perches should i use PVC or wood? Do i need more than two? What is the best way to secure a perch?

If i were to use the waterfall would that be an ample water supply for the GTP? Or would the moving water frustrate him/her? I understand that as a species, the GTP is very nippy. I hear some can be handled if they wanted to be, and then others just want to be left alone which is understandable. I have also read that GTP's tend to clam down when they become yearlings, should i wait until then to handle him/her, or should i start while he/she is young in order to help the snake become more docile when it grows?

I am very excited to recieve this new addition. I would like to learn all i can before it arrives in the next weeks. This will be the most i have ever spent on a snake so i would like to make it as happy and healthy as possible, even if it makes my job harder. Any and all information is appreciated and i look forward to hearing everyones opinion. Thank you.
