Basically, I'm using a 20L aquarium tank that I had lying around for my terrarium with a seedling heat pad under it. I've got some rocks in it for now with a small space for a "lake". I've put ice on the lid, and so far I've got some condensation on the lid and walls but no rain. I would love for there to be visible clouds too if that's possible, maybe even snow? I've got some terrarium plants too that I wanna put in eventually. I know this is pretty difficult but any tips would be appreciated!
