the flexwatt is all the heat you need.... you can pick up a heat pad from the pet store but they cost a lot more money... You shouldnt need any heat from above but if you need to get cool side temps up I would go with a ceramic heat emitter... these are a little better than the heat bulbs as they dont suck up AS much humidity but they still kill it... Also make note that they get WICKED hot... like 3rd degree burn melt your skin hot... Id try the set up without the heat from above and see how your temps look.
