hi people, I recently purchased a frailea castanea cactus and I want to know more about it. a few days ago I saw a cactus that had a stunning metallic reddish brown color and I instantly looked at the price but it was soooo expensive so I had to turn away. later I found out that it was a frailea castanea. today I went to a nursery to look for it and I found a seedling that is about 3 cm across that was way cheaper so I bought it. the color was not as shiny but it was acceptable. my question is that will can I make it more metallic by giving it more light and when will it produce seeds? any help is appreciated!
