a good idea but how much do you think it would cost lol
i would still need to run all the same in tank lighting e.g. basking lamp and uv, as uv does not travel through glass or plastic. because the roof pitch is quite flat it might be hard to weather tight the sky light,
looks like i know what im doing lol thanks but this is my first time building anything structual lol, all ive doe is 1 day a week work experance for a builder for 1.5 years and i am half way through my pre trades building course a wintec
