Great thanks for all the help...I actually have my retic in a tub and in the summer it's great but my room gets ultra cold in the winter and I love cold weather but my little ones don't so I been thinking about going back to tanks and putting some mulch or Eco earth in there with a good light bulb to keep them nice and hot along with the humidity cause I use some aluminum foil on the top of the lid so the humidity stays in and don't escape and I cut a hole on the cool side so it doesn't get too bad and the cool side stays cool...so I might do that first and if its not working I'll try a tub second...thanks for all the info keep it coming
