Has anyone had a moonflower bud/s that seem to be a lot larger then normal? I'm posting two photos , One with a pic of a normal sized moonflower bud and one with a larger moonflower bud, I used a ciggaret butt to kind of show the size difference ( It's all I had available to use at the time) Anyways, I was wondering if this difference was a normal thing that happens once in a while or if it's something thats unusual?? .....First photo, Normal size bud...
