Build your own rack system mate, its simple and will cost you very little compared to prices you buy racks for. Heres a link to a DIY rack build on this forum. Also search on the forums for racks and you will find loads of threads about building them. YouTube is also good for video builds of racks.
is it not better to have a few more holes just to be on the safe side? i've actually now put holes all round on the sides and a few rows in the lid. i am new to keeping royals and i just thought i'd make sure that the rubs are well ventilated, besides i like checking on them daily and just spray the substrate on the heated side now and again
