I've read a lot on this forum about this and decided to fix my 20-20% humidity issue... I liked the tinfoil method but knew that if I just did the foil I would eventually tear it up and it would be in a constant state of repair. (I also would like it to be a little bit better looking.) So, here is what I did... Please feel free to comment with your ideas or suggestions! I realize there are a hundred ways to do things, this is just what I did. I took some ridged cardboard and cut it to fit on the inside edge of the screen cover. I then traced out the center where the light fixture goes and a circle where the ceramic heat lamp goes. I then covered the underside with HD foil. On the top I cut and placed black poster-board and sealed the edges with "Gorilla" brand duck-tape. (Only because it's black in color and would look better than silver. IMO) See photos below. It helped raise the humidity from the 20's to 45%. It has been holding right at 45% for the last 2 days since completing this project. Any suggestions on how or, IF I need to bump up the level to 50-55%? Or, just wait for him to shed and decide? One note; I did not use any clear plastic under the center light so I think some humidity might be escaping there, although it does fit tight into the cardboard so I don't think a lot is getting out... The only other uncovered area is where the ceramic lamp is. Do you guys/gals think sealing that center area up with some clear plastic of some sorts will get me that extra 10% I'm needing? TIA!!!
