Just a short update on my cactus seedlings; I had sown mixed seeds in June 2018. Seedlings are now 9 months old. A look at their growth now as we move into the Spring season. Also look at my new plant... Ariocarpus Trigonus, seen at the end briefly. Im no expert but hope you see the beauty of the seedlings.
