bonbon Reviewed by bonbon on . little rice looking things so i go to check on my plants today and there are these strange clusters of tiny rice looking things on some of the leaves of my plant and a little on the side of the container. i check them everyday and they weren't there yesterday. at first i think it's just seeds or something that blew in and stuck (they're growing outdoors) but when i picked some up i could crush them easily and they were watery. i think they might have been bugs or something but they weren't moving even when i touched Rating: 5
