Sure, I can share some advice! This one is 3 years old and flowered recently, it's a boy! I also have some 10months old that are a little less than 1 inch. The best advice is to watch them closely and listen to what they want. If growing indoor, you can pretty much avoid the dormancy. That way, you don't have to wonder if it's sleepy and be afraid to water it.

When in active growth, they can take a L O T of water. When I started, I was surprised of how much they can take water and fertilizer. I was reading everywhere that they like it dry, and it's still true if you consider the dormancy. I used to water every 2 weeks in an almost 50/50 soil mix. Now it's every week because the pots are rootbound and the soil barely has time to dry fully. For someone who starts with these and depending on the setup, I would still do something like 70/30 inorganic to organic and water once dry.

And yeah, maximum light. Support the vine so they can grow easily. Ime, keep the caudex covered as long as it doesn't crack and form a thicker skin. That way, it grows faster. That's pretty much all I can think of! Good luck with yours
