Firesilverblade,
I encourage you to read and research as much as you can, but this is a good starting point:
Pet store kits don't have some things you need, have extra things (some are harmful) you don't need, and bad things that you'll need to replace. Pet store employees often know nothing or are given bad info. Don't listen to them. Do your own research and never take advice from just one person without checking it first.
Offer insects 2x a day. Good staples are crickets, dubia roaches, Phoenix worms, and others. Make sure to dust with calcium powder. Offer collard/mustard/dandelion greens every day.
Never use sand.
Adults need a 40 gallon tank minimum, bigger is better.
Temps should be 75-80F on the cool side, 95-105F on the basking spot. The analog thermometers are very inaccurate, get a good probe digital thermometer or a temperature gun.
Get either a reptisun 10.0 or an Arcadia 12% UVB tube, UVB is very important. Don't use colored bulbs, they are bad and don't let them sleep properly. Only use a ceramic heat emitter (invisible light) at night if your temps go below 65F. Have 12-16 hours of light per day.
Good luck with your new Beardie!
EDIT: lol I just realized this is almost a year old. Ignore everything.
