I would suggest more ventilation, but not too much. IMO I think if you are experiencing consistent condensation you could possibly get bacteria build up, etc... The one downside to increasing ventilation and air flow is a decrease in humidity. The decrease could be small or large depending on your ventilation. But you can always compensate the drop in humidity by placing the water bowl near the hot spot or using a humidity box.

I have a 1" DIA ventilation hole, but to control the humidity I use cypress.

I'm not familiar with the cycling of temps and humidity for breeding, but I'm sure someone will be able to help you out. Although I do know a breeder who used a humidity box filled with moss and is also used as the lay box. Good luck and I hope this helps some.
