PET Method - New Video
 

It's been a few years since I made a PET video. Here is the latest iteration, this time using a seedling purchased from SVO about 7 months ago.

love the video. I'm still using sphagnum since I don't have that many plants yet (that is debatable) but I'm going to pilot PET for my phrags. I think they would do better sitting in water but I don't want to find trays for them...

Too small a pot would dry out too fast. Is there a size pot you would consider too big, or does that matter at all?

I’m curious to see how it goes for other genera!

Interesting question! I’ve grown big plants in very large containers that still have room for more growth after 3 or 4 years. In normal pots, that’s probably considered “too big.” I suspect pot size is less of an issue than other traditionally grown orchid genera. That said, Catasetinae are probably the least finicky of any orchids I’ve grown when it comes to media preference. That may play a role also.

For other genera, a pot that is too big stays too wet in the center, too much water and not enough air suffocates roots. With Catasetinae in their growth phase, I don't think that "too wet" is even possible. They slurp up everything they can get.
