Hello everyone,

I am working with cranberry plants, and I grow them with plant growth media containing Gelzan.

Growth media that I am using for my experiments contain different percentages of N, P and K. I must understand what gelzan contains to understand plants growing under different growth media.

I was wondering what does Gelzan contain? Does it have any nitrogen in it?

It would be great if someone can let me know if they know what gelzan contains.

Note: I contacted Sigma people, and they mentioned sugars in Gelzan. I am particularly interested in if gelzan contains any nitrogen in it.

Thank you all in advance!
