Water orchids potted in lava rock

[cantrell]

Hi, all. I'm currently using both lava rock and Seramis as mediums. I like both, but I slightly prefer lava for reasons I won't get into here. The problem is that I'm not sure how to "scale" lava rock.

I currently soak the orchids I have potted in lava which is a great way to hydrate them, but isn't very scalable (I don't have time to soak more than maybe a dozen plants total). Seramis, on the other hand, is easier to scale since I can add water to the top of the media, or to the tray, and let the Seramis do the distribution which means watering dozens of orchids is quick and easy.

Anyone know of a faster, more efficient way to water orchids planted in lava?

Thanks,
Christian
