I was just wondering how you guys, that use Aspen bedding and a UTH in tubs, measure your temps? Do you measure them right on top of the bedding or underneath on top of the plastic? And, if you measure them on the plastic, would it be too cool on top of the bedding? Just to give an example, say you measure the temp at 92 on top of the plastic, right above the UTH. Would the temp on the bedding be too cool then? Or, to get the temp just right on the bedding, could the temp right on the plastic get too hot then? I know they can sometimes push the bedding around, so I wonder what the happy medium would be? Is the sollution just a very thin layer of bedding so that the temps are close between the two? Hope I didn't confuse you guys with all of these questions. Just wondering. Thanks.
