Ok, so I buy a 24 inch reptiglo 5.0 to cover the whole top of the cage for my uvb?
This sounds like the best bet. Just be sure that the lower part of the cage has plenty of foliage so that if your cham wants to get out of the UVB light, he can
I found some stuff in petsmart 2.1 calcuim/phosporous, could that be sprinkled on crickets?
You definitely do want to supplement your crickets with calcium but you need to buy the kind that is calcium only.. no D3 and no phosphorus. Crickets already have a large amount of phosphorus and adding more interrrupts the cham's calcium absorption.
And put my basking lamp at the highest branch and look for temps 90-100 degress?
You want you cham to be able to sit under the basking light and not run the risk of being burnt. The top of his casque should be 5 or 6 inches from the bulb, at least. 90 - 95 degrees is good for a veiled. To achieve the right temperature without the burn risk you will have to experiment with bulb wattages and distances. With my veileds, I just screw a cup hook into the shelf above their cages and hang the basking light from that. Then you can move it up or down depending on what temperature you need.
I haven't set up a drip system yet could I just poke a hole in a cup for now, water twice a day, mist 3-5, and feed in the morning?
Yep, the hole in the cup method works well. Make sure that you are washing the cup out daily though, or add a lid with a pin hole in it also. Misting 3 - 5 times a day is good but make sure that you are giving him a pretty long misting session with plenty of time for the cage to COMPLETELY dry out between each one. Otherwise, you will end up with a moldy, bacteria filled enclosure. I personally feed my chams in the afternoon when they have had a chance to wake up and warm up.
Also, did you get a screened enclosure for your cham? The glass aquarium will overheat very quickly and doesn't allow for the proper airflow that chameleons need for optimum health. This is a
very important detail that must not be overlooked.
