Hey, I just noticed the pumice, fact is I got some from a nursery here in Penang. The nursery owner highly recommended it to me, saying it's way better than perlite, and that the people in Holland stopped using perlite sometime back and they are all using this. He charged me quite a lot though, he scooped what was about 250gm worth into a plastic bag & charged me RM10! Bear in mind it's not as light as perlite!

If I'm not mistaken, I've posted a photo of this asking if anyone knows what it is, but no one seems to know. Now I know it's pumice! Have to start using it.

Shawn, how do you use it? Are those white stuff mixed with the coco cubes in the seedling pots pumice or perlite?

And is it easy to get agricultural grade perlite in Thailand? What I see here in Penang are almost always the contruction grade!
