Hello Sheena,
Sorry you did not get the answers you were looking for. As the above poster said, it is not intentional that your post was not answered right away. Many members will not answer a post if they do not know the correct information. I will try to help you as best I can.
For your
UVB light....the 7% gives off low uvb emissions and may not be enough uvb for your little guy. I don't know if you can return or not, but there are much better uvb bulbs out there. I don't know what exactly you can get over there, but I will tell you the ones we use here that maybe you can find online. The ReptiSUN 10(Not ReptiGLO 10) is one of the best fluorescent tube uvb's. An MVB(mercury vapor bulb) is UVB and Heat in one bulb. If you want to get a mvb, there is Megaray, T-Rex and Solar Glo(all great mvb's). If you went with a mvb you would want the 100W and your beardie needs to be no closer than 12" to that bulb. If you use a fluorescent UVB(such as the Reptisun) your beardie needs to be 6-8" from the bulb.
As for your temps, since your beardie is still young....your temps for the basking spot should be 105-110 degrees F(40-43 degrees Celsius). Your temps for the cool side should be between 80-85 degrees F(26-29 degrees Celsius). Your beardie needs to be 10-12" from his basking light.
Are you measuring your temps? What type thermometer are you using....a digital thermometer with a wire and probe or an infrared temp gun are going to get you your most accurate temps.
The sand as a substrate is something we try not to reccomend, due to the risk of impaction to your beardie. There are other subtrates that would be much safer, such as slate tile, reptile carpet or non-adhesive vinyl/linoleum or paper towels.
I hope this helps!
If you have any other questions...feel free to ask :wink:
