Which Medium for Flasking?
 

I want to try flasking and there are just too much mediums to choose from. Can someone help me pick one to buy? I was looking at the selections from Phyto Technology Labs. I want it to be as simple a process as possible. Thanks.

You need to select the media that is appropriate for the orchid. if you're looking into sowing Platanthera grandiflora from seed, my answer would be, I really don't know.

You may want to pick up the book:

Terrestrial Orchids: From Seed to Mycotrophic Plants by Hanne N. Rasmussen.

What species are you wanting to grow from seed?

Platanthera grandiflora
