This last season was my first but I did not change my husbandry at all. I ended up with two healthy clutches. I've already started again for this season and I've not changed a thing. I don't think it really makes a difference.
Not to mention, I don't want to risk a RI because I changed temps. In the winter, my temps fluctuate a little bit (not much) and that's it. still maintain my hotspot and I try to keep my ambient temp as close to what it is now as I can.
