I think Doll's most famous hybrid must be Dollgoldii, which is armeniacum X roth. I have a division of a very good one from Orchids Limited, but though it is a multi growth plant, I have not been able to bloom this one.
GS 2 is a size of the "stone" in Growstones. Growstones are more basic. Even after multiple washings, I found that Growstones suspended in RO water will have a pH around 7.0. But, the characteristics of sphagnum moss create a more acid environment, so there is a balancing of the effect. But, I found that I still needed the effect of the lemon juice to end up with a final media pH that was around 6.2.
