I dont use sand for my babies and young juvies.. I use sand for my sub adults and adults.. Meaning from about 6 months old upwards.
Seems like you have everything you need. Just you dont need to use ceramics not with beardies. Beardies are desert animals so like the sun. With a ceramic you dont get light just heat and therefore the beardie will not connect to a heat sorce. Beardies also dont need heat at night unless your house temps fall below about 58F which not many houses actually do.
It's good friends that walk beside you through the good times and carry you through the bad.
