Oops, we were posting at the same time. The heat lamp you will want on your hot side. Are you going to put it on a dimmer? That will help as those lamps can get toasty. Won't take too long to get your temps up once both are set up. Don't rush it, let it gradually increase with the dimmer <provided you use one> on the low side. You aren't too far off on your temps now. Should be an hour or so???? The veteran guys here would know better.
