Activated Charcoal source

[drsue]

I'm new and have been playing around with plant tissue culture. I've done node cuttings from phals as well as vanilla stem cuttings with reasonable (sterile) success.

I wanted to add in activated charcoal into some of my tissue culture vessels but mine is not fine enough and sinks to the bottom.

Anyone have sources for this? Caisson doesn't have just charcoal.

Thanks

(edited to clarify looking for ultra fine charcoal for tissue culturing)

Thanks!

I've edited my post to clarify I'm looking for ultrafine activated charcoal for growing orchid seeds in tissue culture.

If you want some good quality activated carbon then try Bulk Reef Supply. I don't use the ultra fine for my reef tank so I don't know if they have it. If not ask them if they know where you could get it. The are very helpful.

Couldn't you use a blender or food processor to make it extra fine?
