Bob usually answers within a day. I have a Pro Products PH3 RHP in my Pro-Line cage but its just my QT cage as I keep my house warm so flexwatt works better for me. I got 3 Animal Plastics T10s and 3 T8s that I use flexwatt in.
You can have the RHP drop shipped to AP. I would call Ali at AP and ask her. I ordered all my cages by calling her as the LED lights isn't listed on their website so you have to actually talk to her to have them out on. My guess would be you would talk to Bob and after you figure out the size RHP you need, tell him to drop ship it to AP. Then call Ali and give her a heads up so she can add a notation to the order.
You would want to bake or freeze the ReptiChips before water, otherwise you are going to have one heck of a sauna in your oven or a block of ice you are going to need to thaw out lol.
