Thank you for your response and condolences. My issue wasnt from over heating but under heating. We had a very harsh winter (30 days of temps below freezing which is rare for Mississippi) and I lived in an older home with horriable heating and hard wood foors and could not keep the ambient temps right. As much as I loved the ease of the tubs I would like to have a better display as well as the ability to maintain the temps and humidity. I thinking males for size and from what i've reasearched so far the AP T8 has an accessory divider. But is there a question of housing them seperatly in this fasion? I would think that it would not be as different as the rack i used previously. But if my thinking is worng on this please advise.
