I've read on some of the other threads that catts with blind sheaths can fill them with buds at some point - but I have a few that still seem empty after 4 or 5 months. They're still green and healthy looking, but I'm fairly sure there's nothing inside. Is there anything I should be doing to encourage them? A bloom-boosting fertilizer? More light? More water? Less water? (I have a feeling the answer is just to wait and see, but I'd hate to miss an opportunity to learn more about cultivating these monsters.)

Thanks for any help -
