So I am using flexwatt in my racks to heat my tubs. My question is, is it safe for me to set my flexwatt to 102 degrees. The only reason I am doing this is because my tubs dont sit right in the flexwatt, because I made the spacing a little too much, I had to put thin pieces of hardboard under the tubs to keep the containers flush against the top, so they are sitting anywhere between 1/8-1/4 inches over the flexwatt. So is keeping it at 102 safe to transfer the heat through the air and still give them a decent amount of warmth?
