Do you think there would be any issue with cutting a screen piece into the lid? This would be for a heat lamp! I live in Washington and it can get a little too cold in the winter. Do you think the heat lamp would ruminate or melt the plastic? For anyone that has used these tubs do they/you just set your house heat and go by that? Our house is old and has no room/house temp. So I need to monitor the exact temp in the terrarium. Of course, if the lamp will melt the plastic I have to rethink this whole idea. My plan is to pick up a female to go with my male and house them in a tub similar to this.
