Orchiata contradicting info??

[greenpassion]

I have some of my phals in a mix of orchiata and spag, and some in straight orchiata. I have thus far had continued success with watering them by checking the roots, and holding off until they are silvery/white-as well as how light the pot feels. My concern was wondering if I'm waiting too long to water the ones in straight orchiata. I use the medium size chunks. I do know that due to being on the heat matt, they all tend to dry faster than if I weren't using heat. I am surprised to hear that the smaller size holds moisture longer. You'd think the larger the chunk, the more water it'd hold. Perhaps it's the density in using the smaller size that is the reason?

And I know I tend to micro manage, as there are absolutely no signs of distress with any of them! I need to remind myself that if it's not broken there's nothing to fix!
