It's going to be pretty much the same info as for any large constrictor. Temps will be 80F cool side with a 90F hot spot. Humidity I would guess around 70%.
As for how to tame them, again same as any large constrictor. Give it until it's eaten 4 or 5 meals, then work on slowly earning trust.
I imagine they grow the same rate as retics which is fast as heck. So I would expect the baby to hit 7' in a year. They top out around 13-14' I believe.
And every snake will have it's own personality. Some will be calm and tame easily, some will never like people and some will just tolerate it.
Bottom line is you need a big cage and big food for them. Caesar my SD retic is just over a year old and already pounds jumbo rats every 7-10 days like they are candy. They leave a decent lump for about 2 days. Just remember, you will be dealing with a strong and large constrictor in a couple years that if you decide you don't want it anymore, you will probably have a fairly hard time trying to rehome. Just keep that in mind as something like a retic or burm is going to be a big commitment.
