I laready gathered most of my materials and prices and it shouldnt ruin my bank even with vet bills. The size matters i know but 5cm off the recommended minimum seems like not that important? Also the mesh, all mesh on the cage will be aluminum one as you said, only the top might be bigger in size to allow more UVB through, less dense one if that would help? All other things i've already figured out, from building it through roach colony, supplements /Calcium only and multivitam with D3 and A occasionaly?/, lights, draning system, plants and decorations.. i don't think i missed anything, you can read my summary of my plans on my other post
here, i would greatly appreciate your quidance if something is off there, or if you answer some of my questions there!

Thank you alot in advance, really appreciate your time, i want to build the best home on budget for the lil guy!
