Basella alba growing tips (alugbati, saan choy, pak plang, mồng tơi, malabar spinach)

Spring is a time for planting I'm currently obsessed with trying to grow malabar spinach. I've never tried it before, but it's supposed to be a super vegetable and easy to grow (and tastes like spinach). I'm ridiculously excited about growing it. It's an Asian veg, so I figured to ask you all for tips. Here's my seedlings. I'm assuming these are the first leaves.

- When is the best time to transplant them into a larger container?
- Do I need to stake them right away or will it take them a little while before they grow shoots?

Google only gives basic info and I've tried Youtube, but there's only hippies showing off their already grown plants.
(BTW, it would be really nice if there was a Gardening Club)
