How much am I going to spend to set up his tank for a bearded dragon

My sonr brought home a bearded dragon tonight from a friends house, My son is 7. He brought him home in a 10 gallon tank & I know he needs a bigger one, he also brought home a purple light which is on right now for heat. I am wondering how much I am actually going to spend on setting up the right tank for him..

How many rocks do I need to have in the tank & how many trees do I need to have in there, I have seen a couple of pictures witha little reptile hammock & I would love to get one from somewhere but have no clue where to go.. How much is the calcium dusting & all the stuff I will need I am in Missouri

I answered your other question about bearded dragons you asked recently. I wrote all the correct information about general husbandry. The purple light is probably not a good idea. Dragons like it bright..and I don't think the black light would even get the right temps. I would get a 75 watt bulb household bulb to put in there until you find out what wattage you need and if the temperatures are right. I'm guessing a 75 watt with a 10 gallon should be alright. You need a digital thermometer with probe to check temps.

He needs a UVB light. UVB is for calcium absorption. I explained it in my other answer. The light needs to be atleast an 8.0 or 8% of UVB. There should be no covering over the bulb and it should be placed on top of the screen of the cage. For hammocks, look for one at your local pet store. Petco or Petsmart should carry them also. If I were you.I would go ahead and buy a 40 gallon breeder tank. It can last him his whole life. I bought one for $80 at a mom and pop store, but I think they run about $100 at Petco and Petsmart. Trees, plants, vines, etc are just for decorations. You really need something for him to bask on. If you have any ponds, rives, etc with some nice rocks..I would get one of those and use. I've even used some of the ones that are usually in ditches driveways, etc. They all look the same. But whatever rock you choose, srub it in bleach and soap, rise, then put it in the oven at 200F for 30 minutes. It's a great way to save on money. If you choose to buy them, I would just get one or two big enough to last him his life, and maybe a log too. One of my dragons will choose her log anyday over a rock. For calcium dusting, it needs to be done atleast 3 or 4 times a week and multivitamins 2-3 times. You put the crickets in a zip lock bag, sprinkle some calcium in the bag, close it up, and shake. I call it "shake and bake" lol. Then you open it up, and let the crickets crawl out inside the tank if you don't wanna touch them or get calcium all over your hands.
