how do my orchids make more orchids?

[tim_r95]

So, I have a couple different orchids now and I was just wondering. How do they make more orchids? I know my miltassia and oncidium just grow pseudobulbs that are sorta like individual plants. And the tolumnia looks like it's growing baby plants from nowhere. Lol. But what about my phal and mini phal? Will they just start growing a new plant from the base of the original one? The hawkinsara looks like its growing kinda kinda like the miltassia or oncidium with kinda different shaped psuedobulbs. The other thing I was wondering was how often or how fast do new growths usually take?
