Ugh that looks amazing, I'm so jealous. Looks like you get more light than I do, but I'll try on the "more water" side, as well as fertilizing. Thanks for the tips!
The _ONLY_ thing I can think of after watching your video is that the house gets cold at night, since we only keep the bedroom fully heated, so my current attempt is on my cactus shelf which I keep warmer.
(The link is appreciated regardless, if I ever got one to "stick" I'd love to propagate it)
Unfortunately our house both gets _very little_ light and is often quite cold so that already precludes a lot of options. Some day I'd love to live somewhere that allows the "room full of giant bushy plants indoors" setup.
