This is a great update, dude. It seems your scare earlier in the year and the renovations to the grow-space that followed have really made an impact. What cultivation changes did you make to your Helis that has them growing so well? That's one genus I'm pretty poor with, but it's more than likely a humidity issue.
The sumatrana is also looking great. I've cranked up the heat on mine and am hoping to see some growth soon. Otherwise it's basically the same size it was earlier in the year (need to stop being so damn lazy with plant accommodation).
Anyway,
on today's update.
