Hey, just thought I'd throw in my thoughts about temperature----keep this one below 30 celcius as much as possible. Ideally, exclusively 26 C or lower. As was mentioned by the previous growers, they don't have to worry about this too much since they live in pretty cool climates. Since you're in Canada, you should be fairly safe, but you mentioned 30C so I thought I'd chime in...while D. regia can tolerate 30C for a few days, it will likely go dormant if given this for a week or more.
Here's advice from another grower (quogue):
"I've grown my D. regia for over 7 years and it's been from Cali, to Brooklyn to a few places on Long Island and it's flowered... cool temps are important. constant 80F heat will kill em. They seem to love it in the mid 60's....I do not let the media get all water-logged. Bigger ones can get thirsty, soaking up lots of water. I kinda let them soak up their water and then add more...I use florescent lights and they love em, although when they do get sunlight the dew will get much more gobby. The bigger they are, the less they like repotting. They do spring back though. They do well in basements under lights... if your conditions are right, they can be pretty easy. If they are not right, then they will be difficult! Sure they might be able to survive 90F heat for a spell, but for an entire summer they won't."

But if you can keep it cool year-round, it's as easy as a Capensis, for sure. Just make sure it gets fed enough to appease its voracious appetite (or fertilized, as suggested by John)!
