Soon all of our babies will be moving into their new sterilite tubs. That is, as soon as I get the flexwatt installed on the rack I built for them. My question is on the flexwatt....

The tubs we are using are 44 inches long. I have read that 11 inch flexwatt can only be cut in 12 inch intervals. This means if I put a 12 inch strip on each shelf in the rack...just over 1/4 of the tub will be directly over flexwatt. But, if I jump up to 24 inch strips, then over half the tub will have flexwatt under it...which seems a bit much to me...

Will a 12 inch strip of 11 inch flexwatt create a sufficient hot side in a 44 inch sterilite 1996?

Thanks for any input!
